What to do if your dog eats chocolate

Date: 15 Apr 2026
By: Laura Hoskins

Can dogs eat chocolate?

Can my dog eat chocolate? The simple answer is no; dogs can’t eat chocolate. Chocolate is a toxic, poisonous substance for dogs, as it contains a chemical ingredient called theobromine, which dogs can’t digest in the same way humans can. Most chocolate also contains caffeine, which again, dogs can’t digest in the same way humans can and is therefore harmful to our canine friends.

Why can’t dogs eat chocolate?

Chocolate is poisonous to dogs, due to the theobromine chemical found in it, which causes discomfort and in some rare cases, fatality. This is why even a small amount of chocolate can be harmful.

Chocolate mainly causes dogs to suffer issues in their heart, central nervous system, and kidneys. Symptoms usually occur within the first 24 hours after your dog has consumed – vomiting and diarrhea are often the first to occur.

What happens if a dog eats chocolate?

If your dog does eat chocolate, look out for these symptoms:

  • Vomiting or diarrhoea
  • Rapid breathing/increased heartbeat
  • Restlessness or hyperactivity
  • Increased thirst and/or urination
  • Increased panting
  • Tremors/seizures/incoordination

It’s important to be aware that smaller dogs can be more vulnerable to chocolate consumption.

What steps to take if your dog eats chocolate

We understand that accidents happen, so if your four-legged friend does consume chocolate, contact 24 Hour Vetcare straight away and try to have the below information at hand, so we can provide you with guidance to help your dog:

  • Be aware of the type of chocolate: Take note of the type of chocolate consumed (keep the packaging/wrapper if possible). The highest levels of theobromine are found in darker chocolate and cocoa powder (found in cakes etc) and both these types, and baking chocolate, are more dangerous than milk or white varieties. Also, be aware of foods like chocolate ice cream and chocolatey drinks, such as hot chocolate. These are also poisonous to dogs and are also worth avoiding, as most dogs are lactose intolerant.
  • Keep note of the amount of chocolate: Be aware of how much chocolate has been consumed. The weight of your dog will affect how serious the consumption is, so it is important to try to understand how much chocolate your dog ate.
  • Be aware of the time: Keep a note of what time your dog ate the chocolate so we know what symptoms to keep an eye out for.

Don’t try to treat your dog at home by inducing vomiting (this could cause further problems), unless our vets recommend this to you when you speak to them.

How to prevent your dog from eating chocolate

  • Store your chocolate in places your dog can’t get to. High cupboards or locked drawers/cupboards can be good ideas.
  • Don’t leave plates with chocolate in places your dog can reach and warn any guests about this too!
  • Offer alternative, safe treats for your dog.

Safe chocolate alternative treats for dogs

If you want to give your dog a safe and tasty treat, speak to our vets at 24 Hour Vetcare for safe, healthy alternatives. We can recommend products suited to your dog’s health and age, which consider options such as:

  • Dental treats
  • Meaty treats such as freeze-dried liver
  • Whole foods such as chicken pieces or carrots

Avoid anything with toxic ingredients, including chocolate, grapes, raisins, onions, artificial sweetener, macadamia nuts, avocado, alcohol and corn on the cob.

What to expect from 24 Hour Vetcare if your dog has eaten chocolate

During your consultation at 24 Hour Vetcare, one of our vets will assess your pet’s condition using a number of approaches, depending on the nature and severity of the symptoms. This will start with taking information about what type of chocolate your dog ate, how much, the time of consumption, and the symptoms your dog is experiencing. The vet will then carry out a physical examination.

Treatment usually includes safe induced vomiting (if it isn’t long since your dog has consumed the chocolate), activated charcoal may be given to help absorb toxins, IV fluids may be given to flush toxins and support the organs. Our vets will provide medication if needed for heart or nervous system issues.

A 24-hour veterinary practice can provide continuous care, giving pets the best chance of a full recovery, regardless of the time of day.

Our 24-hour veterinary team is always ready to provide expert assessment, care, and emergency advice, giving you peace of mind no matter when an emergency arises.

If you have any doubts about your pet’s health, get in touch with our 24 Hour team at 24 Hour Vetcare. With a group of 24-hour vet practices, we offer emergency pet care to owners across the country.
