How much chocolate is poisonous to dogs?

If a dog has eaten a full bar of 70% chocolate, that could be serious. But a dog would have to eat a lot more milk or white chocolate to have the same impact.

If you’re worried, call your vet immediately. If your pet can be treated within an hour, they should be fine. Ideally within half an hour.

Ask for an emergency appointment and get them to the vets as soon as possible.

Whatever you do, DON’T try to make the dog sick yourself. This can be extremely dangerous and can waste precious time.

Your vet can assess and treat them quickly and effectively.

The severity of the poisoning is influenced by the amount of chocolate eaten as well as the type of chocolate.

Theobromine and chocolate toxicity in dogs

Cocoa powder and dark chocolate are the biggest dangers to dogs as they contain more theobromine. Theobromine is a stimulant (a bit like caffeine) that is poisonous to dogs.

Dogs that eat a few smarties or a couple of bites of a chocolate chip cookie are unlikely to develop chocolate poisoning. But baker’s or cooking chocolate is highly toxic and any amount could be dangerous.

For milk chocolate, eating more than half an ounce per pound of body weight may put your dog at risk for chocolate poisoning.

For dark or semi-sweet chocolate, eating more than 0.13 ounces per pound of body weight may cause chocolate poisoning in dogs.

Age and general health are also factors that can affect chocolate toxicity in dogs.

Very young and very old dogs or dogs with underlying health conditions or diseases should be treated as higher risk than healthy adult animals.

Due to the large amount of fat in chocolate, some pets may develop pancreatitis (or inflammation of the pancreas) after eating chocolate or baked goods containing chocolate.

We always recommend giving your vet a call for advice or an emergency appointment. This is because it is hard to tell exactly how much your dog may have eaten, and there are so many variables to consider in relation to chocolate toxicity in dogs.

If we are closed, White Cross Vets has an out of hours service run by Vets Now. You can find your nearest Vets Now clinic here.
