How to Get Rid of Growths on Dogs for Under Five Dollars

I am a dog owner who has naturally removed benign bumps from my pet. I like sharing tips how to do this with others.

I removed a benign tumor from my dog's nose using castor oil. Read on to learn how.

Growth on Dog's Eyelid

As most of you probably know, there are many different kinds of warts, bumps, and growths that can develop on an animal. When you find one on your pet, the first step is to identify the growth.

I'm not a vet. I'm just a pet owner with years of experience with dog issues. Personally, I keep my dogs on a natural diet and give them lots of love and attention. When I found a weird-looking bump on the bridge of my dog's nose, I went into panic mode. The growth was very solid and about 1/8" high. It looked just like the rest of his nose, but it was obviously a growth.

The growth on my dog looked like this one, but was on his nose. Imagine how scared I was when I noticed it!

Monitoring Your Dog's Growths

After I calmed down, I began to realize that my dog was older and that bumps will occur as time goes by. It happens to most dogs. So I just put it out of my mind, as it didn't seem to change even after many months.

I can't remember how long it was until I noticed it again. We'd just moved into a new house and he was all excited and running around the kitchen. When I finally looked at him, I noticed that he was trying to look over the bridge of his nose but he couldn't.

I knelt down to see what was bothering him and saw that the original growth was four times as big and had turned blue and blood-red! If you're a pet owner, then I don't have to explain the fear that ran through me. I decided to search for a way to treat the growth myself. I got on the computer and found an answer.

I found information about people whose tumors and other growths were reduced with castor oil treatments. The results sounded promising and non-invasive, so I decided to try it on my dog's growth.

Necessary Materials (Under $5!)

  • Cotton balls
  • Castor oil (be sure it's safe for internal use)
  • A small bowl
  • Very warm water

My Castor Oil Regimen for Removing Bumps

I gave my dog this treatment and his bump shrank until it was gone.

  1. Pour some hot water into a bowl. The water should be very warm, but not burning hot. Heat plays a major role in this treatment.
  2. Sit the dog on your lap. Dunk a couple of cotton balls into the water. Squeeze out the excess and lay them on the growth. Hold until the cotton begins to cool. If your dog does not like this, be gentle and talk to him as you're doing it.
  3. Dip more cotton balls into the water. Squeeze out the excess and pour some castor oil onto the warm cotton. Apply to growth. Leave in place until it begins to cool.
  4. I repeated this treatment three times a day for one week. By the end of the fourth day, the growth began to shrink. By the end of the week, it was completely gone.

Notes About This Remedy

  • Depending on what kind of growth it is, sometimes it goes away in a few days, and other times it may take a few weeks.
  • It's perfectly safe to use castor oil on the eyelid. Just know that if it gets into the eye, the animal's vision might be blurred for a while, but it will clear up.
  • If the growth is inside the dog's nose or mouth, it's a little more difficult to get rid of, but the castor oil should still work.
  • The growth doesn't usually get bigger before it gets smaller. If your dog's bump gets bigger even after a few days of this treatment, I suggest taking your dog to a vet to see what's in the bump.

Castor oil is just one of several at-home wart remedies for dogs. Remember—if you don't have any luck reducing your dog's skin growths at home, or you are concerned the growth is causing your dog pain or discomfort, be sure to take him or her in to the vet.

It doesn't matter what brand it is but it must say "edible" on the bottle. If you can take it by mouth, it's edible.

Keri on September 03, 2020:

Can someone give me the make or what type of castor oil please as theres so many varieties to choose from. Thanks x

Keri on September 02, 2020:

Does anybody have before and after photos of lumps on eyelid please?

Peggasuse (author) from Indiana, USA on May 24, 2020:

To reddoggie: Keep doing what you're doing and don't worry about squeezing out more water. That's not important. What is important is that you apply a very warm and wet piece of cotton to the bump for about a minutes, and then take that same piece of cotton, pour some castor oil on it and apply it to the bump, holding it in position for another minute. Then repeat over and over, until the water gets cold.

Do that 3 to 4 times per day...

Peggasuse (author) from Indiana, USA on May 24, 2020:

To Lori: It's hard to say how long it will take. If it's a major bump, one week is not that long. Are you sure you're doing it right? Go back to the article and check. I would continue to apply the castor oil and warm water for at least a few more weeks to see if there is any change. With some bumps, it just seems to take longer, according to other people who have tried this...

Lori Gregory on May 13, 2020:

I have been doing this 3 times a day for a week now with no change in the wart. How long do you do this? Are there some warts it does not work for? Thanks!

reddoggie on May 06, 2020:


My dog is 15 years old and is in good health. she has something that started out small about the size of a bean on the side of her head. and in the the last year its has grown to 2 inch by 2 inch. it started bleeding because she was rubbing it all the time, and that seemed to make it bigger. i found your site and thought, with a dog this old i want to try it.

But when i read it my brain got things mixed up and i was only doing it 3 warm and 3 warm with oil, and only twice a day.

when i didn't seem to be doing much a light went off in my head that i must be doing something wrong, so i came back and started reading once again and realized WOW i was way off. so for the last three days i have been doing it the right way. today is the 4 day and i'm starting to do it 4 times a day.

She is way to old to take her to the vet and have surgery, and Anastasia is so hard on any dog exp the old ones. i'm going to dedicate my time to her with this.yes its time consuming but i get lots of one on one time with her.

She is great i get the stuff ready call her up on her bed and she just stay's there knowing that at the end she get's a treat.(at this rate she is going to get fat) better fat than lumpy

I have no idea what this lump is only that it started off small and her rubbing it and making it bleed all the time seemed to make it grow bigger. its red and bumpy and looks like warts. now its not bleeding as much as before and it's seems to be staying the same. but it's only been 4 days. so we will see.

My question is. i know its dunk and place. and that its the heat that helps to absorb the oil. now your to squeeze out as much of the water as you can. so if it just warm and moist it still should works?

To Lupita: I'm so happy for you and your dog! :) And I know how you feel about it being a relief. I felt the same way when it happened to my dog and I finally found the answer.

Thank you for posting it here. It will give encouragement to other pet owners who experience the same issues. Have a great day. :)

Lupita the Senior and Beautiful Pug on October 28, 2019:

I want to take the time to thank you for these great tips!! Lupita is 14 years now, and she started having this awful bump growing on her nose week by week. I was so worried thinking that it would need surgical removal and at her age this would be definitely a very dangerous procedure! And then I found your article, and within 3 weeks the bump was completely gone!!! AMAZING!! I wish I could send you pictures for you to see the shrinkage process of the bump, it was just incredible! Thank you again for sharing!! You definitely saved us and her a LOT of unnecessary worries!!!

Peggasuse (author) from Indiana, USA on October 25, 2019:

To Ashlee barrella: I'm always so happy to hear the positive results that castor oil can have. Thank you for posting it here. It helps give others the confidence to try it and succeed. :)

To Jessica: If this was my dog, I would definitely try the castor oil treatment first, before anything else. I would try it for a week and see if there were any positive results. Whatever tests your vet suggests can be done in the near future if the castor oil doesn't work. But if you read all the testimonials that have been posted here, you can see how well this treatment works without vet intervention.

So the bottom line in my mind, would be to first try the easiest solution and see what happens.

Jessica on October 24, 2019:

We adopted our retriever mix over a year ago. Her medical record said that she has a cyst on her left ear. The color was pink and small. It never bothered her. She has seen the same vet since her adoption and they never felt concerned.

About 2 weeks ago, we were rough-housing and it must of gotten pressed or scratched and it bled. I placed pressure on it and applied neopsorin. It formed a scab an looked as if it was drying up. The scab fell off, don't know how, and it then formed a larger raised reddish "cyst".

We took her to the vet and she said it could be a histiocytoma or mast cell tumor. She prescribed her Panalog and Benadryl 50 mg twice per day. She gaves us options to aspirate and see if the pathologist could diagnose it, or to have part of her ear removed. That would ensure that there were clear margins and no chance of leaving any "bad" tissue behind.

We took her for a second opinion, this vet said it would be best to cut it out and send it for pathology for diagnosis. If it came back as mast cell, then return for a second surgery to cut more of her ear tissue to make sure it was all gone. He said that Panalog would do nothing for it.

In your opinion, would you aspirate to see what the mass is? At the same time, start castor oil treatment as you have stated?

Thank you.

Ashlee barrella on October 22, 2019:

So I read this post because my dog is 13 and he’s been getting those growths He has lumps all over and he’s too old to go through surgery but I use the Castor oil the last four nights and they are almost gone this is a miracle

Peggasuse (author) from Indiana, USA on August 01, 2019:

I don't know much about mastitis in dogs but my search on the internet came up with some information. Apparently, it's an infection of the mammary gland and can be treated with antibiotics. Here's the link to that article:

If I were you, I'd take my dog to a vet and let him administer antibiotics as soon as possible. I can imagine that you dogs' condition must be painful, as I myself had the same problem after I gave birth to my daughter. My doctor gave me some medication in pill form and the problem was gone quickly.

I don't know if castor oil can help this, but it would seem to me that it would be easier and faster if you took your dog to the vet and let him treat her...

goodluckiswithme on August 01, 2019:

HI Peggasuse

I am not too sure if castor oil and be use for dogs mastitis?

Yes anyone tried before?

If yes, how should I apply it. thank you

Peggasuse (author) from Indiana, USA on June 27, 2019:

To Lexi: I'm so happy that the castor oil treatment is working so well for you. And yes, in the future, if something like this ever happens again, do go directly to the person who may have caused it. Like you said, if nothing else, you'll make the vet aware of what he/she may have caused.

I had a situation like this once, where I took one of my two dogs to the vet to have her spayed. When she got home, she started getting diarrhea. The day after, my other dog came down with the same thing.

I was upset about my second dog because he was older and his symptoms seemed to be much worse than the female dog. Anyway, I called the vet because being in his office would have been the only way my female could have contracted the virus.

He gave me some advice about what to give them (free, of course) and said that if it didn't help in 24 hours, to bring them both in (again,free, of course.) Fortunately, the symptoms disappeared before I had to take both of them to the vet. But if I had had to, you can be darned sure that I wasn't going to be the one to pay for that visit.

Everyone assumes that doctors (vets) included, know exactly what they're doing. I'm sure there must be a few, at least. But for the most part, I believe in having the responsible party do the right thing. But if they don't see it my way, I point out how bad their attitude is for business, making sure that I tell everyone I know, what happened.

I think this might sound like I'm a little angry at the medical profession and that wouldn't be wrong. That's the whole reason I wrote this article. Glad it's helping :)

Lexi on June 27, 2019:

Just saw your response and wanted to give a quick update. I never contacted the vet as I felt that it would be hard for me to prove the cause of the bump. However, looking back I wish I would’ve if for nothing more than to make them aware of such incidents. Nonetheless, I’ve been doing the castor oil treatment since my first post and I saw results immediately. After the first day, the redness had gone down significantly and it seemed to be bleeding less. Now, the bump has almost completely flattened out. It just looks like a black scab, which I’m hoping means it will be falling off in the near future.

Peggasuse (author) from Indiana, USA on June 19, 2019:

If I were you, I would first call the vet that gave him that vaccination. If it was the vet's fault then he should be the one to fix the problem without you paying him additional money. Check that option out first.

Next option (if #1 doesn't work), go ahead the use the castor oil treatment. Castor oil is good for infections and may clear up the whole problem.

But again, call the vet first and don't let him get away with faulty service. If it's his fault, you shouldn't have to pay for it.

Let me know how it turns out...

Lexi on June 17, 2019:

Hi. Thank you for all the info. My 1 year old Shih Tzu has a raised, very red bump about 1 cm long. The bump seemed to occur after he was vaccinated about 2 weeks ago and has since been consistently bleeding and then scabbing over. I have put a little neosporin on it as I am worried about infections but it doesn’t seem to be improving. I can’t afford a costly vet bill at the moment. I have purchased the castor oil and am hopeful it will help.

HerbiAR from USA on April 04, 2019:

Take care of your pet animals like dogs and keep them free from infections and skin causing diseases with regular application of castor oil for dogs.

Castor oil is applied on dogs skin to treat skin infections. It helps to reduce itching on the dogs skin. The oil is an effective treatment for tumors in dog.

Peggasuse (author) from Indiana, USA on December 29, 2018:

It can be any brand but it should say "edible" on the label, or suggest that it can be taken orally.

Renee on December 29, 2018:

What kind of castor oil is safe?

Peggasuse (author) from Indiana, USA on October 12, 2018:

To EileenKL: Yes, it's normal for the growth to go through all kinds of stages before it goes away. Just keep on doing the treatment as directed and see what it looks like in about a week...

EileenKL on October 12, 2018:

Hi. Thanks so much for all this info. I thought my little dog had a wart in the middle of his back between "shoulders", coz that's what my FORMER vet said. I clipped the hair (which she didn't do) after it began growing. It appears to be a fatty lipoma, similar to ones I've seen on previous dog babies....RIP. I have done 2 treatments and the lump now has red spots on it. Is this normal? Thanks!

Peggasuse (author) from Indiana, USA on October 09, 2018:

To Tammy: I'm assuming that you're talking about giving your dog castor oil internally. If that's the case then no, castor oil isn't good for liver or kidney issues in dogs, according to what I've read when doing research about it. Apparently it works differently in dogs than it does in people...

Tammy on October 08, 2018:

How is castor oil on liver/kidneys? I have to watch what I use for Sadie, she's going on 12, has insulin dependent diabetes, autoimmune platelet disorder, kidney stones..... a boarding place lost her in real country 15 min after I left her, she was 5. I missed my nieces first bday party and Sadie was in the woods for a month! Weighed 16lbs when I left her, 8 when I got her back, she looked like a different dog.... poor girl, all these issues probably from organ damage. There was a drought that year, she was spoiled rotten so not used to being Moreno than 10' away from me......

Peggasuse (author) from Indiana, USA on October 05, 2018:

To Percyshuman: Sounds like you're doing all the right things. I can't honestly speak to the bloodroot/turmeric/lecithin treatment because I have no experience with those. I only know about the castor oil treatment because my dog had a major growth and the castor oil got rid of it.

Let me ask you a few questions though. You said the vet gave you antibiotics for the infection. Was the bump infected? Did it seem to hinder the dog’s ability to walk? Did the vet take a biopsy or aspirate the growth? Before you can treat something, it’s best to know exactly what it is. Did the vet tell you exactly what it is?

If I were you, I would go back to your vet (or to a different vet) and ask him/her to at least aspirate the growth to find out what’s in there. That might lead to a different answer as to how to treat it.

I spent a couple of hours on the internet, trying to find an answer for you but until you know exactly what you're dealing with, it's hard to decide how to fix it. I think you need more information before you can decide what to do...

Percyshuman on October 04, 2018:

I’ve obsessively reviewed all your comments. We are using VERY warm water, almost too hot, so sometimes I need to wait a few seconds before applying to Percy’s paw. I purchased the same brand of castor oil that you use to be sure no issues with that. If anything, I’m using TOO much oil cause I am making a bit of a mess. I am trying my best to rule out human error as an issue. Some days, I’ve only done 2x per day because of my work schedule. Weekends 4x per day. We began the treatment Sept 20th, so today is our 14th day.

I also read in your readers comments notes regarding bloodroot as well as turmeric/lecithin concoction. I purchased but was hoping to get your thoughts on whether I should add this to his treatment. His growth is definitely growing. I have a feeling that it would be even worse without the c/o treatments!

Thank you so much again. Percy is the most precious animal I have ever met. I refuse to allow a couple of bumps to take him out of this world. He has a brand new baby sister that he adores.

Percyshuman on October 03, 2018:

Hi! Thank you for your response

Percyshuman on October 03, 2018:

Hi! Thank you for your response

Peggasuse (author) from Indiana, USA on October 03, 2018:

To Zoey: Yes, it's safe to treat the growth in her ear with castor oil. But because it's in the ear canal, you might have to use a thick Q-tip instead of a ball of cotton. Just do it the exact same way, but with the Q-tip and when you're finished, dab off any excess.

To Percyshuman: Are you sure that you're using really warm water? I'm not talking "hot" just very, very warm. The heat of the water should make the skin more absorbent and softer. I've said this before in other posts, but these growths seem to heal in different ways. Usually the situation looks worse before it gets better. The fact that it bled out is a good sign. So just keep using the treatment with very warm water and see what it looks like in a couple of weeks. It would have to totally drain and then close up before it starts to go down. Let me know what happens.

Percyshuman on October 01, 2018:

Percy is a 13 year old schnoodle with congestive heart failure. Given his condition, he is doing quite well. 3 weeks ago, I found a tiny, teeny tiny, bump on the pad of the 2nd toe of his back right foot. Our doctor (actually 2) and I agreed that surgery was not a good option given his heart situation. He is taking an antibiotic to prevent a secondary infection but otherwise no suggestions from the doctors.

I found and began your treatment almost immediately. The bump has evolved from 1 to 3 bumps that have kind of merged. It’s now the size of a macadamia nut. For many days it was soft and bright red with a lot of bleeding. Now, the bleeding has mostly stopped. The bump is bigger and harder, less bright red.

I am going to enthusiastically continue the castor oil treatment because I literally have no other options.

Any thoughts are greatly appreciated!

Thank you again for this article and giving us all so much hope!

Percyshuman on October 01, 2018:

THANK YOU for this article

Peggasuse (author) from Indiana, USA on October 01, 2018:

To Carolyn: A lot of times, the growth has to drain before it will disappear. That's probably why you notice the bleeding. So I'd just let it bleed out and keep using the treatment until you see results...

Carolyn from Los Angeles on October 01, 2018:

Hi Peggasuse,

I don't put the cone on her until we go to bed..the other times i just watch her as she likes to rub her head. The warm compress causes it to start bleed, however I'll keep doing the treatment.

zoey on September 30, 2018:

Is it safe to use the castor oil ( or is there something else that you would recommend ) on a small growth that is visible just inside the ear canal?...the growth is a greyish color & bleeds on occasion when we clean her ears? I have been giving her a turmeric supplement powder on her food for the last 6 months, also.

Peggasuse (author) from Indiana, USA on September 29, 2018:

To Carolyn: If you keep doing the treatment, chances are good that it will disappear eventually. I know sometimes, with these growths, they will hang on for a while, and at other times, they just disappear in a week.

If you feel bad about keeping the cone on her, then take it off when you're with her and can watch her, but put it on when you're gone. That way, she's won't be living in that cone 24/7.

I would keep with the treatment until everything is gone. And keep a positive attitude. So far, the treatment is working. The lump is gone and things are better. That's how I would handle it...

Carolyn from Los Angeles on September 28, 2018:

Thank you...I usually put the castor oil on and then the poor Lucy has been wearing the cone on and off for 2 months...The lump has gone down..but now it's at a standstill..I just wish it would burst and be done. Thanks.

Peggasuse (author) from Indiana, USA on September 28, 2018:

To Carolyn: Well, castor oil can cause diarrhea if the animal ingests too much of it. But you can avoid that if, after each treatment, you sop up the excess from the growth. Castor oil, especially when applied with heat, is absorbed deeply into the body. So I'd wait a few minutes after the treatment to allow the oil to penetrate the skin and then sop up the extra castor oil. It should be fine...

Carolyn on September 26, 2018:


My little dog licks Lucy’s lump on her head too. I was worried about her injesting the castor oil. So it’s ok for Isabelle to lick Lucy’s lump even with the castor oil?

Peggasuse (author) from Indiana, USA on September 25, 2018:

To claudette: Dog saliva does have antibacterial properties such as the enzyme lysozyme, which breaks the chemical bonds in bacterial cell walls, and the antibody, immunoglobulin A, which directly attacks bacteria.

Castor oil also has antibacterial properties which, coupled with heat, helps to disinfect and shrink growths on animals as well as people.

It contains a large amount of ricinoleic acid which is used as a antibacterial and helps the whole process.

Sometimes, when the animal licks the effected area, the saliva, by itself, will cure the issue. But if that doesn't happen, then you have to go to the next step.

I personally like the castor oil treatment because it works so well. It's easy to do, it's noninvasive and it's a better cure than surgery because after the castor oil has done it's work, the growths don't usually comes back in different parts of the body the way they do after surgically removing one.

claudette on September 24, 2018:

my boxer's litter mate has been licking the growth for over a week now...could not stop her and now the growth (looked like i cut off my thumb and glued it on his ear) is getting so small and looks like it is drying up! it must be the saliva, does castor oil combined with heat have any of the same properties as saliva? my neighbor is using your castor oil instructions and she says it is working on her boxer. we have one half of the original litter between us, but her other dogs pay no attention to each other's litter medical needs. my two boxers have been like one...connected to each other's needs. thanks for your advice and hope other people out there, will let their dogs heal one i have found out, they do know what they are doing. Great article with great results. on September 09, 2018:

Yes Peggasuse! Thank you and I know you are right regarding persistence. His bump looked so much better this morning! The warm compresses do seem to make the bump larger but overall the result is that it looks better and is smaller by the end of the day. It is reassuring to hear that it won't make matters worse. I would max out my credit card to get rid of this thing! Unfortunately I don't think surgery would work for a variety of reasons, primarily the location. @Carolyn, I use Immunity Tree but recently discovered that it may be constipating so am skipping a few days to see if that clears up. Your little white pup in your picture looks like my pup with the bump a Bichon. I have a soft cone on him some of the time. When he scratches his bump it seems to be accidental since it doesn't seem to itch or be aggravating to him. I cook for my dogs but am thinking of switching to raw. I have read of so many benefits from a raw diet.

Carolyn from Los Angeles on September 09, 2018:

Thank you Peggasuse...persistence is what I need to do.

Peggasuse (author) from Indiana, USA on September 08, 2018:

To the last few people who worry about castor oil making things worse: Castor oil will not cause cancer. I don't know where you read that but in all the research I've done, castor oil in some cases, actually helps to reduce cancer growths. It never causes it. Don't believe everything you read on the internet and check to see who wrote it.

When I was originally doing research on this, I searched the internet for two days straight, to try to find an answer. When I finally did, I tried the most logical application and it worked.

I notice, from all the comments I've gotten here, that sometimes, the growth does get larger and then bursts. Sometimes it just shrinks. It all depends, I think, on what sort of growth it is. Sometimes it takes months for the growth to disappear and sometimes it takes a week.

The key, I think, is to keep doing the treatment and not give up. Seems like, these days, we expect situations to take care of themselves in record time. Sure, you can go to a vet and have the growth removed, but most people won't or can't afford to do that. But castor oil and warm compresses (and YES, DO use warm compresses), is non invasive, not painful and a lot less expensive and it works!

I'm not a vet. But I can't ignore the many cases (and that includes my own), where the castor oil treatment has eliminated a growth. The trick seems to be: castor oil, heat and persistence. I would suggest doing the treatment, just like I did, and don't give up.

Carolyn from Los Angeles on September 08, 2018:

So kind of Colostrum did you use. My dog's bump has gone down with the castor oil treatment, but it's 6 weeks and seems to have stopped doing anything and yet if / when she rubs it, it starts to bleed again. I would LOVE to have her stop wearing the cone. Any info you can me would be helpful.

Christine on September 07, 2018:

I don't know whether the large growth on my dog is cancerous or not. It is round with an overhang at the bottom, like a ledge.I can slip the tip of my finger under it. I have been applying the castor oil for the last 24 hours with heat and it seems larger. I just read that castor oil will make a cancerous growth worse. Is this true? A needle aspiration was done that was inconclusive. I have been to 3 vets all insist on surgery which seems senseless since they also acknowledge that it is too close to his eye (less than 1/4 inch) to get anywhere close to an adequate margin. I'm desperate to resolve this for him. It doesn't seem to bother him. He lays on it and does try to scratch it but I know it must be bothersome. It is so big! Please advise as to whether I should keep putting on castor oil or is it true it will make a cancer worse. on September 06, 2018:

Thank you for your informative article. It is one of the few things giving me hope at this point. I have an older dog with a large bump by his eye. I have tried and am trying a variety of things (improved diet, working with a vet homeopath) to get rid of it. I put colostrum on it after he had scratched the bump open a few days ago. That seemed like the miracle cure however it was initially drying things out but has now sealed the bump which has swelled. I put warm compresses and castor oil on it then read in purported Edgar Casey info that heat should not be used on an open wound. Have you been able to determine in what you have researched whether using warm water and castor oil on a scab would be ok? Just double checking :-). Hope to hear from you and thanks again for providing this service!

Peggasuse (author) from Indiana, USA on August 23, 2018:

To Carolyn: Number one, don't use aloe vera...just he castor oil Secondly, don't set a time limit. When something is that large and irritated, sometimes it take awhile. Keep at at until it is gone. I can see why you couldn't bandage it. it's not necessary though. But do keep the cone on her if you think it will prevent her from touching it. The shrinking is a great sign! It means it's healing :)

To Williamd48: If he keeps licking it then yes, it will give him diarrhea. After you do the treatment, be sure you pat off the excess castor oil. You could wrap it and see if that works. But the best idea is to give him less to lick by not leaving a lot of oil on there. Even if you remove the excess, the oil will penetrate the skin anyway.

I would pat off as much as possible and see if what he licks gives him diarrhea. It might not. If it doesn't, then just do the treatments. If it does, then resort to wrapping it.

My 13 yr old has these warty bleeding and ozzing yulky stuff coming out of them. More than one Vet says Older dogs get these . They've also said they could remove them but would come right back. So I keep him bathed well and I'm going to try the caster oil treatment..

Also, look up Vet Dr Becker she has a post on these warts and growths and talks about over vaccinations as a cause as well. I will never vaccinate my elderly guys again. I just wish I had been more educated before the past 5 years. I purchase numerous products from Dr Becker and Dr Mercola as they work together. Great products for different issues with our Fur Babies..

williamd48 on August 01, 2018:

My dog is 14 years old and his lipoma is located on his front right foot I know he will lick the castor oil off and my question is, will this cause him diarrhea? Is so what do you recommend.

Lori Gregory on July 30, 2018:

I did this almost 1 year ago and the growth by my dogs nose never came back....took almost a month to go away. Castor oil is SO amazing!

Carolyn from Los Angeles on July 29, 2018:


It's bleeding because the top is cracked. I don't know if it's a sebaceous cyst or bleeding wart. None of the vets tell me what it is, except to say "well we'll remove it and then give to the lab. UGH....Anyway...since the other's "shrinking"'s going down from being a high lump to now a more flattened lump..It's bleeding a bit less and I keep the cone on her. I just wish I could keep the bandage on it to get it to heal faster. But it's in such a weird position that each time I wrap her head it move backwards in a short time and I don't want to wrap it hard on her head. She breaks my heart but is a great trooper when it comes to meds and such. Just long should I do this before I "give up"...a month or two???? Also some recommended pure aloe vera ...have you tried that?

Peggasuse (author) from Indiana, USA on July 28, 2018:

To Carolyn: So maybe it's only bleeding because she keeps rubbing and irritating it, and not because it's an unusual bump. Use the treatment and see if you can figure out some way to stop her from rubbing it. Maybe between the castor oil treatment and her, not irritating it, it might start to shrink and heal.

Castor oil is a natural antibacterial so using it might start to kill the infection and thus, stop her from rubbing it. She might be rubbing it because it's itchy. The castor oil might stop the itch.

I can relate to how you feel about the vet situation. Been there, done that. And this is why I try to find alternative methods to healing something...

Carolyn from Los Angeles on July 25, 2018:


Thanks for your reply. It's bleeding because once it stops she'll rub it on the floor and bam, opens up again. It's not bleeding a lot. I've been to 9 vets since moving back here 6 years ago and I still don't have one I love. They are all so expensive, surgery happy or dismissive. It's quite frustrating. No one has clearly told me if it's a bloody wart or a sebaceous cyst or something else. She has many other pink fatty lumps..but this is the only one that contains blood. I've started the castor oil treatment last night. Thank you again. I'll keep you posted.

Peggasuse (author) from Indiana, USA on July 25, 2018:

To Carolyn: Yes, I would try the castor oil treatment. Just follow the directions in the article and watch it carefully for the next couple of weeks. I wouldn't try to stop the bleeding. Just wipe off the blood before you do the castor oil treatment and then continue, as directed in the article.

Maybe it's bleeding so much because it's irritated or possibly because there's something inside the lump that's trying to drain out. I'm surprised that the vet can't diagnosis it. Sounds like money is the factor.

Anyway, I'd try the castor oil for awhile. If you don't see any improvement in a couple of weeks, I would go look for another vet who believes more in holistic medicine than money.

Let me know how it's going after awhile...

Carolyn from Los Angeles on July 24, 2018:

My 12 year old beagle has a lump on her head. It's the second time it's been there. Vets want 700-3000 to remove and after 3 vets I still don't have a diagnosis for exactly what it is. Now it's bleeding...I've tried Iodine, cortizone spray, peroxide, Afrin spray and nothing is working to stop the bleeding. She's been wearing a cone for 3 weeks now. I'm running out the drug store to get the castor oil and PRAYING this will work. I don't want to put her under for surgery.

Peggasuse (author) from Indiana, USA on July 24, 2018:

It's normal for the growth to sometimes bleed. It generally means that it's breaking up, and that's a good thing. If I were you, I'd wait for at least another week before I took him to the vet. I'd keep doing the castor oil treatment and see if the growth begins to heal. It's up to you of course, but usually, these kinds of growth always look worse before they get better. The fact that it's bleeding is a sign that the castor oil is doing it's job. I would be patient for a little while longer. You can always take him to the vet but I'd give the castor oil a chance to do it's job first...

Melissa on July 23, 2018:

Hi. I don't know what kind of cauliflower looking growth he has on his lip. Vet says some kind of papilloma. So I've been doing this for a week and has been bleeding a lot lately. Is this good? He bled a lot today and im scared when I'm at work and he's bleeding alone. Is this what's supposed to be happening from this warm water and castor oil? He has a vet appt Friday and I don't know what to do regarding surgical emoval being it's in a bad spot on his lip as well. He's 13 years old and I really don't want him going under anestesia.

Peggasuse (author) from Indiana, USA on May 18, 2018:

To Romeo05: If it doesn't say "edible castor oil," then read the back of the bottle. If it tells you how many teaspoons or tablespoons to take, then that means it's safe to put into the body. That's what's meant by "edible." You can eat it. If it says "for external use only" then that's NOT edible and you shouldn't use it.

It can be any brand. It just depends on what's available in your area. Personally, the brand "Humco" is the one I use. You should be able to get it at any Walmart (that's where I get mine) or at a drug store or health food store.

And yes, the treatment is exactly as you described. Make sure the water is very, very warm but not hot...

Romeo05 on May 17, 2018:

What is edible castor oil as none of the products say that. The oils I've found say organic, cold-pressed hexane free. Can you provide several names of edible castor oil.

I have a question regarding repeating it 10 times. Do you soak the cotton ball in water, apply, soak again and add castor oil, apply and do this with the water and castor oil 10 times 3 times a day?

Peggasuse (author) from Indiana, USA on May 07, 2018:

To Cira: It has to be edible castor oil because it's being absorbed into the body through the skin. Since it's edible and made to be taken internally, only the edible kind is perfectly safe.

To zeke118: I'm so glad this is working for you :) I have heard that sometimes, it also works without heat. Maybe it depends on what type of growth it is. I'm not sure. What I do know is that if it works, do it!

zeke118 on May 07, 2018:

There is a TON of improvement. I would say it has been reduced to half its size already, this by just dropping drops of castor oil to the tumor, not even with the warm water. The tumor is usually black, it looks like scabbing. When I apply the castor oil, the scabbing falls off and it is bright red underneath. It looks awful at that point, but within a day, a new scab has formed and the growth is smaller. Thank you for this help!

Cira on May 07, 2018:

Hello and thank you soooo much for you replies. Yes I am using the edible one (laxative)...why does it have to be that one?

Peggasuse (author) from Indiana, USA on May 06, 2018:

To Cira: If it's turning colors, then the treatment IS doing something. From the reports I've gotten, sometimes the growth does turn black and then it may bleed or it may just dry up and fall off. I would continue the treatment because something positive really is happening. Just because it's being stubborn, doesn't mean it won't disappear. Just keep at it.

I hope you're using the laxative (edible) type of castor oil and not the kind that you can't ingest. The other kind isn't meant to be taken internally. So you MUST use the edible kind....

Cira on May 06, 2018:

Hi me is Sunday and it will be a month on Wednesday and I don't see any difference in size. Would it be possible that it may take longer? The only difference I see is that it went from a reddish color to an almost blackish color in the past 2 weeks. Also why does it have to be the laxative kind of castor oil?

Peggasuse (author) from Indiana, USA on May 02, 2018:

To John: I'm so happy to hear that the castor oil treatment worked for your dog. About treating cancer tumors with it, I have read that castor oil can help that too. I know that if I had a dog with cancer, I would try it first, rather than have a vet remove it because from what I've heard, it's hard to get rid of cancer altogether. Usually it reoccurs somewhere else on the body, even after the original growth has been surgically removed.

That's one good thing about the castor oil treatment: Once the growth is gone, it doesn't come back in a different area of the body. I've seen and heard some amazing reports about this treatment and personally, I would use it first, before I would try anything else.

Thanks for posting your results. It may help some people decide to try it first...

John on May 02, 2018:

I was amazed at how well this worked! My lab had a growth on the lower part of her ear about the size of a Brazil nut. The vet said removal was major surgery in excess of $500.

I did not think that was money well spent for a 12 year old dog. Due to the size of the growth I did not expect caster oil to work but decided to try it anyway. I bought a 1 inch paint brush and caster oil at Walmart and painted the growth twice a day. After about a week the growth turned black and in about another week it fell off! Has anyone thought of trying this on cancer tumors!!

Peggasuse (author) from Indiana, USA on April 27, 2018:

To ChardiesMom: I'm so happy for you! Thanks for posting the results here. It will help others with the same problem, and show that the castor oil treatment really does work :)

ChardiesMom on April 27, 2018:

I posted 3 weeks ago that my dog had a red bump on her eyelid. I started this treatment immediately and within a few weeks it was gone. Thank you so much for this at home treatment that was easy to do and didn’t cost a lot of money!! And I appreciate it so much that you still respond to questions and concerns after all these years.

Peggasuse (author) from Indiana, USA on April 24, 2018:

To Cira: I'm sorry to hear that the treatment doesn't seem to be working. All I can suggest is what I would do if it was my dog. I would continue the treatment for another week and see if there were any positive changes. It is odd that the growth looks bigger. Usually, that doesn't happen. It sometimes begins to flatten or it will bleed and start to break up.

About the warm water, initially, you should start out with very warm the temperature of water that you would take a bath in. After applying the cotton over and over again, the water will turn cooler and that's when you should finish the treatment.

The whole point of using very warm water is to open the pours so that the castor oil can get in more easily. So when the water is no longer warm, then end the application until the next time.

Keep in mind that, depending on what type of growth it is and how large it is, seems to determine how long it takes to disappear. From my own experience, it can take a few days, up to a month.

The way I look at it, using the castor oil treatment can't do any harm to your dog. So before you have to resort to taking her to the vet, I'd just continue with the castor oil a little longer and see if it gets any better. Sometimes, after you've done it for awhile, it just suddenly begins to shrink. I would keep at it for awhile longer and see what happens...

Cira on April 24, 2018:

Hi, I found your article last week and thought this could bring a miracle instead of putting my dog through surgery and the vet said it would cost about $1200. I started the procedure on my terrier mix on Wednesday so tomorrow will be a week. She has a small round tumor the size of a chickpea on the outer corner of her left eye near the nose, it is a dark reddish color. I have not seen any changes yet (maybe a little bigger) even though I am consistent at 3x a day. How do you keep the water warm after 10x of soaking? Is getting slightly larger normal? Should I continue this treatment?

Peggasuse (author) from Indiana, USA on April 21, 2018:

To zeke118: Well, if applying castor oil with a dropper is the best you can do, then I would still give it a try. The heat from warm water helps the growth shrink faster, but it may still help without the heat...just might take a lot longer. Do it for a month and see if there is any improvement...

zeke118 on April 20, 2018:

My dog is not very placid and growls if I go near his growth (it is on his snout near his eye). There is no way he will let me do this treatment. The best I can do is to drop some castor oil on it with an eye dropper. His growth is about 1" X 1.5", so somewhat large. Am I wasting my time but not holding the cloth over it with warm water? Will it help at all to just use the castor oil as I described?

Peggasuse (author) from Indiana, USA on April 19, 2018:

To Berniesmom: Thank you for confirming what happens sometimes, when the castor oil treatment is used. Some people get alarmed when they see changes in the growth like color or even bleeding. But the fact is, those changes usually mean that the growth is breaking down. Thank you for your comment. I'm sure it will make some people feel better...

Berniesmom on April 18, 2018:

I notes that the color of the wart changed as well and was initially alarmed! But I kept at it- using a cotton ball and it worked like a charm! I also found that soaking the cotton ball in the oil was most effective!

Peggasuse (author) from Indiana, USA on April 18, 2018:

To parksark: When it starts to bleed, it generally means that the growth is breaking up and that's a good sign. And yes, this does happen a lot. My suggestion is that you keep up the treatment and let the growth bleed out. Also, you should be using a cotton ball, not a Q-tip because the cotton will cover more of the effected area.

Naturally, you can do what you feel is best but in my experience, as well as many who have left comments on this page, there's no reason for alarm. It's just what happens some times, when the growth begins to break down. If you see blood coming of there, just blot it up with a damp cotton ball and continue treatment...

parksark on April 17, 2018:

I just attempted the procedure on her eye. I used a Q -Tip soaked in warm water and then in the castor oil. By the second time there was blood on the Q tip, by the 3rd there was more. I stopped with that.

Anyone have such reactions?

Peggasuse (author) from Indiana, USA on April 16, 2018:

To Jodi: That's fantastic! Thank you so much for describing exactly what happened and what you did to make it happen. It will help others who come to this site, to see how successful this treatment is.

Again, that's for your feedback :)

Jodi on April 16, 2018:

Thank you! This worked! My 2 year old yellow lab got one of these bumps on the edge of his ear. I took him to the vet and he confirmed it was histiocytoma. My vet said it may resolve itself in 2-3 months or if it got too big or bothersome we could have it removed. Well it was getting bigger by the day. I saw this post and gave it a try. I did it 3 times a day for 3 weeks and now it is completely gone! The warm water with the castor oil would make it scab up then the scab would fall off. Every time the scab would fall off the bump would get smaller until it was gone.

parksark on April 15, 2018:

I will let you know how it works!!!

Peggasuse (author) from Indiana, USA on April 14, 2018:

To parksark: It very well might. Just be aware that the treatment causes blurriness for a little while after you do it but it's harmless and it clears up quickly. It's a lot like when you put drops in your own eye. For awhile, your vision is blurred but then it clears up. Just follow the directions in the article and see if you see any changes within a week or less. If the growth is small, it shouldn't take long than that...

parksark on April 14, 2018:

My 5 year old Vizsla has an eyelid neoplasia. I have been looking for a "natural" treatment as I am not crazy about surgery and knocking her out.

Would this treatment work for her?

Peggasuse (author) from Indiana, USA on April 11, 2018:

To Peppers Mommy: None of them have returned. I know that a lot of times, when people have growths surgically removed from their pets, the same growth comes back in another part of the body. Fortunately, this doesn't seem to happen after using the castor oil treatment. After I used it on my own dog, I never saw another growth, anywhere on him...

Peppers' Mommy on April 11, 2018:

Have any of the warts you treated with Castor Oil returned?

Peggasuse (author) from Indiana, USA on April 10, 2018:

To Marilyn: Do whatever works. And yes, the water does get cold fast. That's why each treatment only lasts about 10 minutes. But, that's enough. If you do it three times each day, it should be enough to take down the growth...

Marilyn on April 10, 2018:

My Rotti does not like it! So then I got the idea to fasten the cotton balls to her head and upper leg with knee high panty hose ~ problem solved! And she looks adorable! Now I just need patience. I find the water gets cold very fast.

Peggasuse (author) from Indiana, USA on April 07, 2018:

To ChardiesMom: Yes. It's: warm cotton ball, then warm cotton ball with castor oil on it, then warm cotton ball again, then warm cotton ball with castor oil on it, etc. Just repeat the same action over and over, about 10 times in one sitting, and do this three times each day.

The reason I suggest that you do it 10 times per sitting is because that's how long it usually takes for the water to get cold. Once it's cold, it's not as effective. I noticed that it's the very warm water plus the castor oil, that makes it work...

ChardiesMom on April 07, 2018:

Have a question. I just read your instructions again. You said you did this 10 times. Do you mean that you did warm cotton ball then warm cotton ball with castor oil 10 times in one sitting? Then repeat this 3 times a day? Thanks

Peggasuse (author) from Indiana, USA on April 06, 2018:

To ChardiesMom: I notice that sometimes, the growths that look really bad (red and irritated), seem to be the easiest to get rid of. Just do the castor oil treatment the way I described it in the article and see if you notice any positive changes within a few days. What you described sounds like something that castor oil can fix in a short time.

And yes, I keep up with the comments that I get because answering them is important. I know how I felt when I saw the growth on my dogs nose and didn't have anyone to turn to.

Just so you know, I check for comments twice each day, and answer them right away. Feel free to write to me, anytime. :)

ChardiesMom on April 05, 2018:

So glad that I found this article. And amazed that you’re still answering questions all these years later. My Golden retriever developed a reddish bump on her upper eyelid. Alittle bit smaller than what is shown in the picture above. I did some research online and saw this article. Went out and bought castor oil today. I’ve done 2 treatments already. My dog is so sweet and doesn’t mind the cotton balls being pressed on her eye. I’m hoping this works and we can avoid the costly vet visits. Thank you so much for posting this article and I’ll keep you updated.

Peggasuse (author) from Indiana, USA on April 04, 2018:

To BernardDavid: I am SO happy for you! I know how happy you must feel because I felt the same way when the growth on my dogs nose began to shrink. Castor oil is my hero too. :)

BernardDavid on April 03, 2018:

Thank you so much!! We have been using the castle oil and the wart is almost completely gone!! Disappeared before my eyes:) This saved me (a very worried Dog Mom) lots of $$ On Vet bills!!!

Peggasuse (author) from Indiana, USA on March 30, 2018:

To BernardDavid: Yes, it seems to be a common result of the effect of the castor oil on the growth. I would just keep doing what you're doing until the growth is gone.

I would suggest though, that if you see that it's swelling or looks infected, take the dog to the vet because it might be a tooth problem, like an abscess. In which case the vet would have to give antibiotics to kill the infection and then possibly pull the tooth that's causing the problem.

In either case, the problem is fixable. Just keep an eye on it...

BernardDavid on March 28, 2018:

I just started using this for a wart on my dog's gum line. I have only done a few treatments and it's turning the surface of the wart a darker color. Is this something others have seen? It is not painful or interfering with his eating! Thank you in advance- Bernie's Mom:)

Peggasuse (author) from Indiana, USA on March 07, 2018:

Sorry, I haven't tried the treatment with baking soda, and I really haven't heard anything about it. I can't recommend it cause I haven't tried it.

Personally, I wouldn't use peroxide because peroxide has a tendency to close a wound and that's not what you want. If you're using the castor oil treatment and the growth breaks and begins to ooze, then you need to let it so that the infection can drains. When it does, the wound will close, all by itself.

SMLeader on March 06, 2018:

Can you explain the addition of baking soda and if you recommend doing that? I read about it and peroxide somewhere in the thread but couldn't find any other information on it.

Peggasuse (author) from Indiana, USA on February 24, 2018:

To Roger Franks: My understanding is that topical castor oil and edible castor oil have different ingredients. The ingredients of edible castor oil are what makes it work on shrinking growths. So you need to get and use only edible castor oil. It should say that on the label.

I'm sure that there must be several companies that make this, but the brand name of the one I used is "Humco." I usually get it from Walmart, but I'm sure that you could pick it up in a drug store or a health food store as well.

Sometimes it doesn't say "edible" but it will say something that refers to taking it internally like "all natural laxative" or "odorless and tasteless" etc. Hope this helps...

Roger Franks on February 23, 2018:

Hi! You say use castor oil that is safe for internal use only, I have some Aura Cacia brand that is organic but says for external use only. Do you have a brand you recommend and what is the reason for it having to be safe for internal use of its being applied topically?

Peggasuse (author) from Indiana, USA on February 23, 2018:

To Steve: I'm so happy that it worked for you. Castor oil really is a miracle drug. :)

To Kenneth Vaughan: I'm pretty sure it will work. So many people have tired it, as you can tell by the number posts here, and those who got back to me, couldn't praise castor oil enough. Just follow the instructions and see what it looks like in a week....

Kenneth Vaughan on February 22, 2018:

I've just got through reading this article about how to remove the small bump on my beagle's nose, and I am very anxious to proceed with this remedy.

I certainly hope it works!
