How to Care for a Dog in Heat

Personality-wise, female dogs and male dogs really aren't all that different. There are dominant and aggressive female dogs just like certain male dogs. There are submissive and calm female dogs just like certain males. So when deciding if you want a male or female dog, your main concern will typically be the dog's size. Females are generally smaller than males (not always but generally), and you'll want to decide whether or not you want to get the female spayed.

I personally think that unless you have the intent of breeding, you should get your dog spayed or neutered because it is healthier for the dog and you prevent unwanted pregnancies. However, it is always up to you, the pet owner, as to what you want to do. If you have decided upon a female dog, you'll probably want to brush up on some information about dogs coming into heat and what a spay involves.

Commonly Asked Questions About a Female Dog's Heat Cycle

Here are some frequently asked questions about a female dog's heat cycle.

When will my female dog have her first heat cycle?

Generally, a female dog will come into her first heat sometime between the age of 6 months and 24 months.

When your female dog comes into her first heat will depend on the dog's breed. Typically, small dog breeds come into their first heat sooner than larger dog breeds.

How long will my dog's heat last?

Typically, heat will last an average of 18 to 24 days.

How often will my dog go into heat?

Dogs typically go into heat once every five to eight months, so about twice a year. Although, this will vary per dog. Smaller dogs can go into heat sooner than larger dogs.

What are the first signs of my dog going into heat?

The first sign of your dog starting her heat cycle is a swollen vulva and bloody discharge from the vulva. For the first week or so, the female dog will attract the attention of male dogs, but she usually won't allow them to mount her.

After the first week or so, she will actively court male dogs and will allow them to mount her. At this stage, the vulva may become slightly smaller and she may not have as much discharge or have a clear discharge instead of bloody, but she'll still be in heat and can still become pregnant.

Why is my dog having bloody discharge again after her heat cycle?

Typically, when your dog has her first heat, it will be a "split heat" in which she will develop a swollen vulva and have bloody discharge but she won't actually ovulate (release eggs) or let male dogs mount her. But about two to six weeks later, you'll probably notice that she's in heat again; this is your dog's first real full heat cycle.

Will my elderly dog go into heat?

Older female dogs do not go through menopause, but after seven years, your dog's heat cycles will get further and further apart.

Dealing With a Female Dog in Heat

First off, if your female dog is an indoor dog, you'll probably want to purchase a dog diaper, whether that be the dog diapers with disposable liners or washable dog diapers. Otherwise, you'll have blood spots all over your carpet, tiles, or wood floors. You can find the dog diapers in sizes from extra small to large, and sometimes extra large.

Keep Your Female Away From Males

Next, you want to make sure that you keep your female away from male dogs, which means that if your female dog is an outdoor dog, you want to make sure that she is properly pinned and no dog can get in or out of your yard. I would actually recommend bringing the dog in the house or in an enclosed outdoor patio until her heat cycle is complete.

Seal Up the House

For indoor dogs, you want to make sure that all doors and windows are shut all the time and you keep any unneutered male dogs that you may have away from the female.

Disguise the Scent

You can consider applying a little dab of menthol rub under the female's tail to disguise the heat just a little and to stop potential suitors. You can also use the menthol rub on your male dogs by putting a dab on the male's nose to make the female's scent—make sure whatever you use is dog-safe and in a location where it can't be ingested.

Chlorophyll Tablets

Sometimes you can mask the smell by giving your female chlorophyll tablets. Just remember to ask your vet for the exact dosage before you give your dog any medicines.

Avoid Activity

Try to keep her as calm as you can, which means avoiding overly strenuous play, but make sure that you still dote attention tofo her in a more calming manner such as brushes and massages.

Why You Should Spay Your Dog

Consider spaying your female dog. Know and understand when you should spay your dog, why you should spay your dog, the process of spaying your dog, and the risks of spaying your dog.

Remember that spaying your dog will reduce the risk of breast cancer in the future. You want to aim for before her first heat, but since you're reading this, I'm assuming your dog is already experiencing her heat cycle. Shoot for after her first heat and before her second, otherwise, the risks of breast cancer are the same as a dog who was never spayed at all.

Ages to Spay

If the dog is older than two, you can still reduce severe health risks, as long as the dog is less than five years old. After five, an unspayed dog has greatly increased odds of developing a uterine infection, which can be fatal if not caught early. The treatment is surgery to remove the uterus.

She urinated and opened her bowels as normal but still is acting strange. Hasn't been in contact with any males either. Is this normal and is she just being abit of a baby ?? I try to give her cuddles but she just shy's away from me which Is most unlike her ?? Help!!

nina smith on May 28, 2013:

t on October 26, 2012:

This was very helpful except she did swell about three times her usual size, is that too much ?

robyn on April 14, 2012:

I have a poodle cross who is 6 months old and she has just come into heat, when can i get he spayed?????

Holly Mackenzie Cupp from United States on April 05, 2012:

Hey Stacey - I just saw your comment on here and I think you should take your dog to see your vet. That sounds like Parvo. Has she had her shots? Parvo is very serious and you need to get her in to the vet right away.

stacey on March 30, 2012:

I have a female dog and im just wondering why is she brining blood up in her sick????? she was on heat about 3 weeks ago and both the dogs done the deed!!!! so can anyone tell me why she is bringing blood up in her sick???

can someone tell me when a female German shepherd is on heat. and how old will she be when she doe's go on heat .and is there any sings of the female on heat with out you knowing about it . doe's the females bleed right away when they are on heat.

Hope on January 14, 2012:

So after the female dog gets spayed she will not have her period correct.

Holly Mackenzie Cupp from United States on December 18, 2011:

thank you so much for this hub! I was freaking out as I was told my dog just finished her first heat and I realized today she's definitely in heat again. Now I get that it's a split heat. Off to get some doggy diapers and making her a future spay appt tomorrow!

ESPELLZ on December 14, 2011:

I have an Italian Mastiff. And she 9mo. And she in heat. And she lay down a lot on her bed. Is that OK.

Maggy on December 04, 2011:

emma on August 13, 2011:

my puppy is on her first cycle and she has started going to the toilet in the house only when we are out or through the night. this is not like her and always is very good for that. could this be due to her being on heat?

jimmy yamuna vihar on July 23, 2011:

what should be the better time for the crossing of german shepherd female during her second heat????

Char on July 23, 2011:

How long does the bleeding last for in the first full cycle (second half of split) in a small dog (poodle mix)?

sumandorji on June 14, 2011:


after i read this i am sure that my puppy is in heat, and i would so much love to have puppies, but, i feel that she might not mate with a breed of our choice, is there any way to make it happen?

Rena on May 08, 2011:

It is perfectly all right to spay or neuter a puppy at 8 weeks, as long as the puppy is healthy and weighs at least two pounds. This is recommended by the American Veterinary Association and the ASPCA. Waiting until after the first heat is an old wives' tale. Spaying a puppy before the first heat reduces her chances of getting breast cancer by 99% and from having an unwanted litter by 100%. Neutering a healthy puppy at 8 weeks or below seven months of age reduces aggressiveness, wandering off, urine marking and humping just about anything in the room.

chrissy :-) on May 02, 2011:

any ideas on how to get a male off the female heat scent or even masking it with something else ??

Amanda on April 19, 2011:

4t-5t pulls up work better for German Shepherds and just cut a hole for the tail. XL doggie diapers are to small. I think next time we will get adult diapers and cut hole for her tail. Our dog doesnt mind the diaper, but we take it off when she goes outside.

Danii on January 22, 2011:

I was wondering, do they have other symptoms like diarriah and drowsiness??

Whitney (author) from Georgia on January 11, 2011:

When the discharge is a straw or clear color, she will be able to conceive.

DeeNeeCee on January 10, 2011:

My pug female was/is in heat my question is how long after she stops bleeding is she still able to conceive. Also, I use human diapers with a hole cut out for her tail and it works wonderfully and much cheaper... She's actually gotten use to them and rather do her business in them... Ummm, not happy about that one but better that anywhere but outside.

Whitney (author) from Georgia on January 04, 2011:

Without veterinary training, it is hard to tell especially very early on. SEE A VET!

tinker on January 03, 2011:

and like in between the 2 bumps there's a thin line and the 2 bumps are kind of hard

tinker on January 03, 2011:

i touched her stomach and she has like 2 bumps by her vulva

Whitney (author) from Georgia on January 03, 2011:

It is possible. Again check the link that I provided above. Also, see a vet to see if they can tell you for sure. If it is early, the pregnancy can easily be terminated.

tinker on January 02, 2011:

could my female dog be pregnant because the dog got her more than one time.

Whitney (author) from Georgia on January 01, 2011:

Unfortunately, she's probably pregnant. It is probably still early to terminate and spay her. Otherwise, you may want to start preparing now. I've not heard of a swollen vulva being a sign so early on, but a vet could better give you more information. She may not have taken, which would be good as well.

Tinker on January 01, 2011:

I've seen her with another dog

Whitney (author) from Georgia on December 31, 2010:

Have you had the female around a male? If so, then it's highly likely, but I'd say otherwise, no. It's hard to say yes or no without any other specifics.

Tinker on December 30, 2010:

what if my female dog's vulva is swollen for almost three weeks? Does that mean that she is pregnant? Because she is not bleeding anymore.

sam on December 30, 2010:

my 3year old female has been in heat for about 2 weeks now and are male dog has mounted and got into her once. how often should i let him do that to have puppys? she wants it all the time. But its weird she wont breed with the dog upstairs only are male

Whitney (author) from Georgia on December 26, 2010:

I wouldn't recommend breeding her.

tushar on December 26, 2010:

dear i hav some problem i hav 5 years old pomerian female n i didnt cross her yet bcoz my mom was against this thing now i want to cross my female pomerian but she is 5 years old so now its goood for her if she birth dogs.......

Bliss on December 21, 2010:

Ok, thank you :D

she is about 1kg at the moment :)

Whitney (author) from Georgia on December 21, 2010:

Many vets will spay at 8 weeks of age. For small dogs heat comes earlier than larger dogs, which means spay a littler earlier. You want to spay before first heat. You can get it done at 3-4 months or so, and still be before first heat. This way, the pup is a little older and has a little more weight, making surgery safer.

Bliss on December 21, 2010:

Hi :)

A few days ago we got a little girl puppy, she is only 8 weeks old but my mum is talking about getting her spayed already. (we are definantly getting it done... we dont want any puppies)would a vet be likely to spay her now? and if they did would it be bad for her? her dad is a Bichon Frise and her mum is a Malitese/Shih Tzu so she is only a small puppy and will probably be a small dog...

Thank you

Adopt a dog if you want a pal for her. You won't find a stud dog without papers and champion lines and titles to your dog's name.

Just adopt!!!

Liv on December 17, 2010:

I was just wondering because, I would love to have another dog. I also know that my poodle would love someone to play with, while I am gone during the day. I have already checked around for a stud poodle or yorkie but i haven't found one in my area that is willing to breed for "pick of the litter". I also don't have her papers because, I was given this dog from someone (who used to be my neighbor)who did not take care of her properly. Which makes it even harder to find a stud dog.

Whitney (author) from Georgia on December 16, 2010:

Backyard dog breeder!

No need to make mix breed puppies when there are plenty that need homes at the shelter.

To purposely breed mix breed dogs just because is ignorant.

Liv on December 16, 2010:

idk if this will help...but i forgot to tell you that he is part pug.

Liv on December 15, 2010:

My toy poodel is in heat and i want her to be able to have puppies...My sisters boy dog is going to stay a couple of days at our house. I wanted them to mate but he is younger and weights like 18 pound...and my poodle only weights 8. We are keeping him outside for now and watching them very carefully but they seem to be VERY interested in each other!

could they mate?

He is a mix and has lots of fur and on the other hand she dosen't shed ....

would the puppies shed alot?

Whitney (author) from Georgia on December 13, 2010:

Some females don't like the male you've chosen. Some females just won't breed. If she's not comfortable or doesn't like the male, she won't breed.

trpldc99 on December 12, 2010:

i have a female pitbull. this is her 4 heat that she has gone through. but she refuses to allow the male dog to do anything. why ?

Whitney (author) from Georgia on December 08, 2010:

18-24 days is average, but it can be shorter or longer, depending on the do.

Maria on December 08, 2010:

Hi! My 6 month old JRT has been in heat the past 19 days. She still has a light colour discharge and I am wondering how long more will it last for? I'm suppose to leave her with a friend that has a few dogs at the end of December so I'm getting worried that she might still have her heat! In the other hand I read that it normally lasts up to 21 days, so is this true? or could it last longer? Thanks

kenia on November 25, 2010:

nvm i saw the link sorry about that.

kenia on November 25, 2010:

hi i have a dog that just went into heat today. i'm scared of spaying her but we DON'T want to breed her. what is the spaying process? surgery? if so can anything go wrong?

Megan on November 21, 2010:

Hi Whitney!

I have a 6 month old mix puppy (lhasa/pom/poodle) who just went into heat 4 days ago. We were in the vet having her pre-op done before being spayed when they told us she was in heat! So now we have to wait.

We currently live at my boyfriend's parents house. They have a 8 year old black lab who has never been fixed. He has been around female dogs who hadn't been spayed and he did not try to mount. But this is my question:

Is it possible for him to try and mount her or get her pregnant being that he is so old?

She has been in her heat cycle for 4 days. We are planning on being away from the male when she is near the time of possibly getting pregnant, just in case. Around what time should we leave to avoid her getting pregnant at all cost.

Also, when she is done with her cycle will the swelling of her vulva decrease back to the size before she went into heat?

Thank you!

Whitney (author) from Georgia on October 31, 2010:

I've not heard of loosing hair as a symptom of going into heat. I'm quite surprised that the shelter didn't have the dog spayed before you adopted or right after.

laurie on October 29, 2010:

We adopted a dog 2 months ago with the agreement that she was spayed, well she just came into heat. We are keeping her indoors and waiting for it to be over so she can be spayed. My question is she seems to be also loosing hair, either that or incredible shedding--any possible relationship?? thanks

Whitney (author) from Georgia on October 27, 2010:

Some males become overly aggressive. I've seen and heard of many that become so aggressive they have to be put down after pups are born. These are dogs who should NOT be bred.

You have backyard breeder dogs. I wouldn't recommend breeding them.

Keep the two dogs separate. The female is not ready to go into heat. I actually suggest spaying her, as you're increasing cancer risks by not.

slimania on October 26, 2010:

first of all great page... alot of info n very helping

my question

i have a home bred english springer spanial (3 yrs), i got a female for it 5 months ago(for breeding). the female recently came into heat... and my male is going crazy ... he wont let her at peace.. hes being aggressive.. fights with her (mounted too ofcourse) and even barks n growls at me when i try to stop him fighting her.. he is super violent and the poor bitch is helpless. he wont let the bitch get close to me or any1 in my house.

im just concerned abt the bitch .. he might get her injured because of the frequent fights

Carol on October 12, 2010:

Very helpful site! My 6 month mini-schnauzer just started her first heat cycle 3 days ago. I was adamant from the start and discussed with my vet that I did not want her to go into her first heat cycle and I wanted her to be spayed as soon as it was safe. However the vet said that I should wait closer to when she was 10 months. I am locked into a one year pet plan with this clinic but after this I will be changing over to a different vet!

Whitney (author) from Georgia on October 11, 2010:

It is possible. Hard to decide 100%, but it's possible. Behavior change can occur because of stress, pain, illness, changes in environment, etc.

Caitlin on October 11, 2010:

This page has been very helpful. Thank you! My 10-month-old pug has just gone into heat for the first time (I've had her about 1 month), and while she is still very calm and almost timid, she has started (rarely so far, thank goodness) getting quite fierce in trying to get to other dogs, and even some people. She is never aggressive with other dogs, but this is new behaviour, and she has even started snarling at some people (she'll pick out random people walking down the street, while others are fine). I'm hoping this is all just while she's in heat and getting used to things, but could this be a sign of a behavioural change as a result of her first heat?

Thank you,


Jordan Lovelck on October 08, 2010:

My Puppy come into heat at 8 months old she wont finsh it till about 17 -18 oct its so anoying i have had 3 males come up to her all unerterd i thik all male dogs should be neuterd unless used for breeding . She is geing spayed after this heat .

Don Simkovich from Pasadena, CA on October 04, 2010:

I take it female dogs in heat should not walk into singles bars. Uh, kidding. Good article. I think dogs make the best pets yet so many people seem not to know as much as they can about behaviors and reproduction.

Whitney (author) from Georgia on October 04, 2010:

I would contact a vet to see if she is pregnant. Some vets can tell as early as 4 weeks.

It can be quite hard on her to have puppies at this age. I would be leery. Although, some do it just fine, but complications can arise with older dogs.

The pregnancy is still early and can be terminated if that is what you choose for safety concerns.

richiellfc on October 04, 2010:

i have a small cross lab she about 6 now i have also a pain in the arse lovely male american bull dog about 2 and a half i do keep them away whilst in heat but you never no but as she is older i read that she could have complications only had the male for about year and half so never had intenetion of gettin another dog but hes so lovely with the baby and my other dog there proper boyfriend and girl friend but even though hes bigger she lets him know his place but im not nieve as that know what he could do if ever snaps as we stop them straight away but they are really really good together so now we get to the point moved house and been workin in it as wasnt finished when we moved in now cause everythink has been up the wall he has got to mount her at least twice nieve i can hear you say not at all everythink was just mad been sorted now separte bits but she only just finished her cycle thank god but now the female wont let the male go no were near her and being aggresive towards him which is just not like her thge first time if mounted would of been about 4 weeks but no signs and the other time maybe 2 weeks ago if she is pregnat is this why or end of cycle i would of got her done but as i say she told old now what i read abit neive i no but not normaly ant hepl or views but nice ones as i see some of the answers

Luisa on October 03, 2010:

My puppy just went into her first heat, and with all the precautions that I have taken, I think that one of my other dogs mught have gotten to her. I've read many different things on the internet, I've read how it is dangerous if she is pregnant, and I've read how its not too. How is it dangerous if she is pregnant on her first heat cycle?

BigDaddy on October 03, 2010:

I have a female Saint Bercollie Mix who is one years old. I think her heat is over, but how to be sure. I take her to off leash parks all the time, as she loves to play and run there, but have not been since she first started spotting, month ago. Do tell when is a good time!

Shannon on September 29, 2010:

My girl is in heat right now. She is acting pretty out of sorts and has been sick to her tummy. She's having very loose/ watery poops and has been throwing up a bit.She's also been spending a lot of her time in bed. I'm just wondering if this could be part of her being in heat or if it sounds more like something else. Just wondering if I should take her to see the vet. Thanks!

Carrie2010 on September 29, 2010:

Sorry if my question has already been ansered above... So many to read through! Anyway, My dog is in heat and I am using the doggie diapers. My problem is she continually takes them off or chews them off...any ideas how to keep them on??

Bluecollarbelle on September 28, 2010:

I agree wholeheartedly with the advice you have given about spaying, not breeding young females, and not being a backyard breeder! Thank you for being an educated voice in an uneducated world! I did want to add a comment for the people with the Danes. Giant breeds are generally recommended to go through one heat cycle before spaying to help ensure equal closure of the growth plates. Spaying or neutering should really never be done before 10 months in a Dane. However, this exception only applies to giant breeds such as Danes and English mastiffs. For all other breeds, females can be spayed at 4 months and this WILL prevent several types of cancer and other health issues. Thanks again for your informative article.

Whitney (author) from Georgia on September 09, 2010:

Until she's out of heat, which can be up to 3 weeks.

Amy on September 08, 2010:

My Female Am Staff has just gone on heat she is just over 7 months and we have a 15 month Male, we have sent him off to stay with his "grandparents" as we know she is way to young for puppies.

I was just wondering how long exactly do I have to keep him away from her as she is not liking it one bit and its breaking my heart.

Diana D on August 22, 2010:

My female is in her first heat, and her brother won't leave her alone. I crate them as much as I can, but I have to let the poor things out now and again! I'm going to try menthol on her diaper (thou outside).

How much blood should there be? I'm kind of shocked at the amount, yet she's perky and happy as one could expect. But, wow, that's more than I thought.

Whitney (author) from Georgia on August 22, 2010:

It could be somethign else. Since the dog has been spayed, she should not go into heat. The drainage is more than likely not from being in heat. I would consult a vet.

Amber B on August 21, 2010:

My dog is a 5 year old Queensland/Pit. We had her spayed back in 2006 but I have started to notice that she is musking. We always assumed that it was our older male dog but we don't smell anything until she wanders over. As my dog is currently living with my parents, they have also mentioned finding dark discharge on the floor when she sits down. What is going on here? I thought all of this was supposed to stop after the dog got spayed?

Paige Marie on August 20, 2010:

Hi im paige, Loved the article. It was really helpful. I own a 2 1/2 year old Doberman, Ripley, and what i found helpful to keeping all the males on our street ( 2 doors down from us a family owns 2 mastifs and boxer, all males and NONE of the nutered :\ that just made it harder on us ) Was when im outside with her and shes in heat is right after she goes to the bathroom is to hose down the area with water so that way the scent isnt that stong, also she is a big dog so she needs a lot of running time and i live out by a jogging trail so every morning or late night when not many people are out is to take her out on a quick 20 minute jog then back home for a nice rest. We're considering on breeding her either her next heat or the one after that with a friend we've made at the dog park. He breeds show quality dobermans and is trying to improve the breds health and get rid of those "Z factor" dobermans with all the heath issues and says she could make a real good show and heathly pup. Shes made quite the friends with one of his males, Striker. They're just adorable to watch when they run around and tease eatchother at the dogpark. If we do plan on breeding her its one litter and done! I dont wanna where the poor girl out :P But i dont know yet with reading all the health benefits I just might have her spayed. Best of luck to all the first timers with dealin with the dreadful heat! Haha, Thanks so much -Paige Marie

A vet can tell as early as 3 weeks by performing an ultrasound. You would be able to tell as early as 6 weeks without a vet. Knowing earlier than later is good in this case, as the pups would be way too big for her to have safely.

You could have the pregnancy terminated, and have her spayed

So how will I know if he has injected himself into my chiuauah??? Can dogs have abortions like us??? What do I do??? I do not want pups!

Whitney (author) from Georgia on August 10, 2010:

He would attempt, but it is not safe for your dog to get impregnanted by him, as it would kill her, the pups being larger than she is.

I have a small chuahua whom is in heat. She has attracted a dog from somewhere now he does not want to leave. This dog is a big black lab. Is it possible for him to get her pregnant since she is way too small for him???

Found this very helpful having never had a female dog before. You may want to consider posting something about the trials and tribulations of having a male dog in the same house when you have a female in heat. I have never seen anything like it. He, being a boxer/bulldog cross and she being a rotti/shepherd mix. For a few days of her third week he literally was beside himself, he whined, he trembled, he didn't eat for three days, not even a treat. It was crazy.

I also found Tea Tree Oil as a good deterrent at least for a bit to mask the smell.

Yes, the swelling should go down. Give it a week, so that it's been two weeks since surgery, and have your vet check her out to make sure everything is ok. Typically, vets will want to see the dog back within 10-14 days after surgery.

I'm not sure if you can help me, but I figured it was worth a try! I adopted a Chihuahua from the humane society a week ago, and they spayed her while she was in heat. Her vulva still appears to be swollen to me, but since I didn't get to see her before she went into heat I don't know for sure. Is it possible that it is still swollen and the swelling will go down in the next few weeks?

thank you soo much. i am now definitely going to get my dog spayed/nuetered!!! you saved me from alot of trouble and money for doggie diapers!!!

Most dog day cares, won't watch if the dog is in heat. Ask your vet. I know a few people who have had their dog kenneled for the extent of the heat at the vet.

We have recently just got a rescue puopy and the shelter were unable to tell us if she had been spayed. The vet said to wait and see if she came into heat and if so he would do it after that. She started bleeding yesterday. She has separation anxiety and can not be left alone and we HAVE to be away for the whole day a week from today. We did have her planned for doggy day care but as she is now in heat they wont risk taking her. Do any day care places take dogs in heat? Are there any other options we havent thought of which will allow her to be cared for during the day?

Whitney (author) from Georgia on July 31, 2010:

It's hard to tell, and not true definite way to determine when the dog will come into heat. Most little dogs will come into heat sooner than older dogs, but again it's hard to estimate. I've heard smaller dogs going into heat as early as 6 months to a year, but it's really hard to tell.

Good job on her first best in show, as well as future competitions.

I have a longcoat Chihuahua who was a present for my 21st birthday - She is 6 and a half months old and took reserve best puppy in breed at her first show!

I have another show coming up in 6 weeks time, and I was wondering if there is any way of telling when she will come into season for the first time? Obviously I dont want to waste money on show fees if she will be unable to be shown.

Also, do you know the rough age that tiny dogs come into season for the first time?


Whitney (author) from Georgia on July 28, 2010:

Some dogs don't go into their first heat until a year to a year and a half.

Rick on July 27, 2010:

Hi, I have a female maltese and she's about to go 1 year old but she haven't undergone her first heat yet. should I be alarmed?

Whitney (author) from Georgia on July 15, 2010:

It is NOT safe to breed an 8 month old dog. Even though females may come to season early, that doesn't mean that they should be bred. Typically females should be at least a year and a half to two years old before breeding.

To potentially reduce risks of cancer, you should have her spayed before she goes into heat. You will have the greater chance at risk reduction. Do keep in mind, though, that about 1 in every 4 dogs develop cancer.
