Is Eating Chocolate Dangerous for My Dog?
Everybody loves chocolate, so it comes as no surprise that Lassie wants some, too. If your dog ate some brownies or stole an unattended bag of Oreo cookies, you have a reason to be concerned, as chocolate can be harmful to dogs. Around Christmas time, Valentine's Day, and Easter, the veterinary hospital I worked for was bombarded by frantic phone calls about their dogs eating chocolate. At the vet clinic, we used to take these phone calls very seriously.
The ingredient in chocolate that's dangerous for dogs is called theobromine. The level of toxicity is determined by...
- the amount ingested,
- the concentration of theobromine,
- the overall health of the dog, and
- the size and weight of the dog.
The effects may range from a mild stomach upset, excitability, to even a potentially fatal cardiac arrest.
But how much is too much? How can an owner know when it is time to rush their beloved pet to the vet, or simply keep a watchful eye on him/her?
How Much Chocolate Is Too Much for a Dog?
It is really difficult to determine exact levels of toxicity, as there are different factors to keep in mind and sometimes the effects may vary on an in individual basis (just like in humans, where one alcoholic drink may cause one to feel dizzy while another may still feel sober on his third).
According to PetPlace veterinarians, as a general rule of thumb, the toxic levels of chocolate for dogs are as follows. (Note that the lower range is likely to cause mild signs whereas the higher range is likely to cause severe toxicity.)
- White chocolate: 45 ounces to 90 ounces per pound of body weight. A 20 pound dog would need to ingest 55 pounds to exhibit nervous system signs.
- Milk chocolate: 0.7 ounces to 2 ounces per pound of body weight. A 20 pound dog would have to ingest a little less than one pound to exhibit nervous system signs.
- Semi-sweet chocolate: 1/3 ounce to 1 ounce per body weight. A 20 pound dog would have to ingest only 6 ounces to exhibit nervous system signs.
- Baking chocolate: 0.1 ounce to 0.3 ounces per body weight. A 20 pound dog would have to ingest 2 ounces to exhibit nervous system signs. All it takes for a 10 pound dog to exhibit nervous system signs is one ounce!
Generally, the darker and more bitter the chocolate, the higher its theobromine contents. It is very important to determine, therefore, the type of chocolate ingested and the amount. This information is often found on the candy wrapper. At the same time, it is also important to know the dog's weight.
Confused by all these numbers? Use this cool tool, a virtual dog chocolate toxicity calculator crafted by veterinarian Dr. Marie by visiting this link: Dog Chocolate Calculator. No guarantees of accuracy can be made.
What to Do If Your Dog Eats Chocolate
1. Keep Track of All the Details
Once you realize your dog has ingested a toxic dose, the best thing to do is to contact your veterinarian and follow their instructions. They will need to know:
- the amount of chocolate ingested
- how long ago it was ingested
- and the weight of your dog.
He/she may also ask you to induce vomiting if your dog ingested less than two hours ago. This is the time when it is still in the stomach.
2. Induce Vomiting
Always keep on hand 3% hydrogen peroxide which will help the dog induce vomiting. Your vet will instruct you on how much to give. Unfortunately vomiting alone may not be sufficient, since some of the theobromine may still be absorbed. Your dog may require further treatment at the vet's hospital. Keep in mind that there is no antidote for chocolate poisoning, therefore, treatment is mostly supportive!
3. Look for Symptoms of Toxicity
Symptoms suggesting chocolate toxicity include the following: Vomiting
- increased urination
- high blood pressure
- high heart rate
4. Go to the Vet
Don't wait for these to happen! the sooner you see your vet the better chances of recovery and the cheaper on your wallet!) Note: chocolate mulch can also cause toxicity in dogs!
These symptoms may only develop after 12 hours post ingestion. Therefore, don't assume that just because your dog is doing fine that he will not get sick. See your vet immediately instead!
- Always keep chocolate and candy bars away from your furry friend.
- Always keep on hand 3% hydrogen peroxide and activated charcoal.
- The quicker you act, the better the prognosis. Generally, dogs treated within four hours have the highest chance of survival. Time is of the essence, so do not delay treatment. Call your vet for advice and follow it carefully.
- If your vet is closed, seek help from a 24 hour animal emergency center immediately or call the ASPCA Poison Control at (888) 426-4435.
Note: I am not a vet and I am not qualified to determine if your dog will get sick or not from eating chocolate. Remember to always call your vet for advice!

Questions & Answers
Question: I am very confused. My pet terrier ate chocolate regularly for her entire life. She died when she was fifteen-years-old. She never had any problems. Now I see warnings everywhere. Why did my dog not have any issues?
Answer: It could be the chocolate wasn't eaten in toxic amounts and/or it was the type that is less toxic (milk, white chocolate).

My dog Went off her food on Tuesday went to the vet Friday and still not eating she had a chocolate brownie.tuesday had injections and medication been hand feeding her will go to vet tomorrow as is long weekend any advice would be muchly appreciated
Leslie on March 02, 2019:
I would not recommend telling people to use peroxide to make their dog vomit. That is how mine died. She ate something rancid, and i tried to make her vomit the item. In the process, the small amount of peroxide was just enough to make her contiue to have an upset stomach for 20 min. Throwing up can cause heart problems for dogs. By the time I realized I had made her worse, I rushed to vet. (Too late) if they eat chocolate just call vet.

My dog ate a few chocolate lambs (aero kind from easter) he won't stop whining and making strange noises and he's being really hyper and drinking a lot of water. His name is Max, he's a miniature dachshund and weighs just about 14 pounds and we don't know what to do. We don't know if we should induce vomiting. He's being very hyperactive. His stomach is also making strange noises. Please help.

My dog got ahold of 6 ounces of chocolate. He is about 55 pounds. I love him so much. Will he be ok?
Adrienne Farricelli (author) on December 22, 2016:
Milk chocolate is fortunately not as toxic to dogs as dark chocolate. More concerning may be the foils if she/he ingested them with the foil. Keep an eye on your dog for any symptoms of trouble and report to your vet if you notice any. Here's a dog who at 20 pounds ate 2 dozen! .http://www.justanswer.com/pet-dog/1zsa9-dog-just-a...

sarah on March 08, 2016:
Our 52 lb mixed breed ate about 1/2 a tray (approx. 10 brownies) which were made with semi-sweet chocolate and 2 oz. of cacao. ALL of the chocolate was of the dark kind. I don't think she vomited and it was at least 7 hours ago since I just came back from work and see that it's gone. She seems fine and is not acting hyperactive or with an irregular heart beat. It is 7:30pm and our vet is closed and also, I think too late to induce vomiting. Any ideas? Freaking out!!!
Shemp on January 22, 2016:
Oh no!!!! My dog is a Chocolate Lab! Will it die!?!??
Sarah gibbs on August 17, 2015:
Hello my dog ate chocolate almost 24 hrs ago we feel and the vets closed any suggestions
Adrienne Farricelli (author) on December 29, 2014:
My article has a link that brings you to the chocolate toxicity calculator, you would put the weight of the dog, the type of chocolate ingested and how many ounces was ingested. Is crackle the miniature chocolate of the larger bar? is it milk or dark chocolate? how many ounces is it? that's the info you would put there. However, I cannot grant how accurate it is ,so a call to your vet to confirm is a good idea.
faith on December 28, 2014:
My 30 pound beagle just ate half of a extra large sized krackle bar. Is she going to be alright?? She seems to be breathing normally...
Jennifer Beckers from Palm Beach County on September 21, 2014:
I knew chocolate was bad but I had no idea so many factors went into it. Thankfully that's never happened to my dogs but thanks now I know what to do if they somehow get into my stash!
Adrienne Farricelli (author) on December 27, 2012:
Animalloverr, my page has been attacked by spammers as you can see, I am working at removing them. As my article disclaimer announces, you should see your vet anytime your dog is sick and especially if he ate chocolate. Please call your vet and tell him how much he ingested, how long ago, the type of chocolate and the weight of your dog. Best wishes!

My dog ate chocolate he want eat he's laying around looks sick please help
Adrienne Farricelli (author) on September 15, 2012:
Your best bet is to call a vet or any emergency vet and tell them the exact ingredients in the chocolate (dark chocolate is worse) along with the weight of your dog; the smaller the more likely they are to get sick from it. best wishes!
Antonio on September 15, 2012:
My dog ate a bailey's ( they are those things with a mix of chocolate and alcohol in the middle and solid chocolate on the outside) and I gave her milk and she drank it all. So I gave her another bowl but she didn't finish it. She was trembling a lot a while a go but she stopped more or less. I don't know what to do! I'm only 10!!!!!

my 50 pound goldendoodle just ate a box of double stuff oreos. Do I need to induce vomiting with hydrogen peroxide?
Adrienne Farricelli (author) on June 03, 2012:
Great, I am happy the dog ate chocolate video was helpful to you, Best wishes!
Worried sick on May 18, 2012:
Awesome! the video from the vet really reassured me, thank you for posting this; it helped me feel better, if felt almost as if having a vet in my living room talking to me.
Adrienne Farricelli (author) on May 17, 2012:
Janet, generally with chocolate toxicity you should see within 5 hours an irregular heart rate, tremors, seizures, hyperactivity. If your dog seems fine, most likely he vomited most of it. The fact he is a lab and vomited should make this unlikely. Keep an eye on him for the rest of the day, best wishes!
Janet on May 16, 2012:
My chocolate lab ate a tray of chocolate brownies about 12 hours ago. I induced vomiting with peroxide about an hour after she ate them. She seems fine, but I'm still worried. It's 1:25 a.m. & I can't sleep cause I'm looking for signs. She's sleeping soundly & I'm wide awake! How long after ingestion should I look for signs?
cristhol on May 13, 2012:
My dog ate a milk chocolate bar and was fine afterward, no diarrhea, no vomiting, not hyper. I guess the dose was not enough to create problems?
Adrienne Farricelli (author) on May 11, 2012:
Well, yes, you should know by now how well the hydrogen peroxide works!
melissa on May 11, 2012:
I just induced vomiting in my lab because he ate a few hershey kisses, only now I saw it probably was not necessary! because he is big and it was milk chocolate, oh well. Sorry Rover! Well... now at least now I know what to do if he really eats a toxic amount!
Adrienne Farricelli (author) on May 09, 2012:
If he vomited withing 2 hours of ingesting it, technically yes, if you think he vomited the whole amount he ate.
brenda on May 09, 2012:
My dog ate chocolate and got sick but was ok afterwards, would vomiting it make him out of the woods?
melissa on May 06, 2012:
Thank, thank you thank you. my dog ate white chocolate and I was getting sick over this, so happy it is not that bad as other types of chocolate.
Adrienne Farricelli (author) on February 17, 2012:
Awww, thank you! These posts make me feel happy and helpful...what and how much chocolate did she eat? Keep an eye on her and if you are not sure about something please consult with your vet.Kind regards!

Hannah, it depends on your dog's weight and the type of chocolate used in the bar, here is a guide for you:
If in doubt, call an animal hospital and they will tell you over the phone what to do.

We have a minature poodle/ bishon that is 18 months old & weighs 20-21 lbs. He ate 2 pieces of dark chocolate (about .5-.6 oz. ). What should we do?
Kat Snack on February 12, 2011:
Hello! I have a miniature poodle puppy who weighs about 5 pounds. A few months ago she got into a half bag of semi-sweet chocolate chips. She ate the ENTIRE remainder of the bag (about 6 oz.) I had no idea she had even eaten it until she started vomiting chocolate. Immediately, I called an after-hour emergency vet. I gave her hydrogen peroxide to induce vomiting. She had vomited at least 5 or 6 HUGE piles of melted chocolate. After about an hour and a half after ingestion, regardless of all the vomiting, she started showing some strange behavior. Her limbs were twitching sporadically and she wouldn't sit still. I decided to take her to the emergency vet. They had recommended a few things - EKG monitoring, activated charcoal, medication to get her heart rate down... I didn't have much money, so I decided on the activated charcoal. Luckily, she had vomited most of the chocolate up now the charcoal could absorb toxins in the stuff that was still in her system. When I took her home, she wouldn't sit still. She reminded me of someone who had had too much coffee. Finally, she got to sleep.
The point is when your dog eats chocolate, it's important to take action. The vet told me if I had not done anything, my dog would have died without question. Depending on the size of your dog, the type of chocolate it eats, and the amount of chocolate it eats, your dog could be in danger. If you are unsure of the amount your dog ate, it's still a good idea to use hydrogen peroxide to induce vomiting if you know the ingestion wasn't long ago. The appropriate dose of hydrogen peroxide is one teaspoon per 10 pounds of body weight.
Hope my experience helps!
Adrienne Farricelli (author) on July 20, 2010:
Greetings, sorry for the delay in answering your question. We are on different time zones as I am vacationing in Europe at this time. Hope your dog is feeling better by now. Just one reeses piece should not be sufficient to cause chocolate toxicity. If your dog weighed 5 pounds it would take 4 ounces of milk chocolate to cause toxicity. A reeses pieces therefore may contain a very small amount (check the label as it may even not contain chocolate at all!)
However, your dog appears to be eating stuff from everywhere? What do you mean by that? Is your dog sort of acting panickly, licking off the floor, walls and eating anything in sight? This may be a sign of nausea or something stuck in the throat such as a foxtail.
For future reference here is a table about chocolate toxicity:

My dog ate a resis pieces then now won't stop eattin stuff from everywhere what should I do?????!!!!!????? =(
Brittany on March 30, 2010:
You should never give your dog chocolate,it is harmful to them. I'm a Veterinary Assistant, I'm always careful with chocolate and I keep it away from my dog.
Adrienne Farricelli (author) on December 01, 2009:
It really depends on the type of chocolate and how much your dog weighs. I would not have given the milk because if the Hershey kisses were the milk chocolate ones, too much milk may cause diarrhea.
If they were the milk chocolate ones the good news is that milk chocolate, is much more "safe" compared to baking chocolate or cocoa. You need to do some math on how many ounces each kiss weighs and how many pounds your dog weighs. Here is a link to a good table for these type of calculations:http://www.veterinarypartner.com/Content.plx?P=A&a...
If she ate just four or five she should be fine especially is she is on the larger side. At worse, a bit of upset tummy and diarrhea may pay a visit.
Rebeca on December 01, 2009:
My dog ate three kisses maybe 4 or 5 kisses i gave him aglass of warm milk but i am still worried.
