Can dogs eat chocolate?
While dogs might love the delicious sweet taste of chocolate as much as humans, it’s important to remember that chocolate is poisonous to dogs and could make them very unwell. So no matter how much your dog begs for a piece of chocolate, remember dogs and chocolate don’t mix.
Here are the reasons why chocolate is bad for dogs:
- Chocolate contains an ingredient called theobromine (a bit like caffeine), which is toxic to dogs. Dogs aren’t able to break down, or metabolise, theobromine like humans can.
- Theobromine mainly affects a dog’s guts, heart, central nervous system and kidneys.
- Darker, purer varieties of chocolate tend to have the highest levels of theobromine but it’s also found in milk chocolate.
- Symptoms of dog chocolate poisoning include vomiting (which may include blood), diarrhoea, restlessness and hyperactivity, rapid breathing, muscle tension, incoordination, increased heart rate and seizures.
- The effect and signs of chocolate poisoning in dogs depend on the amount eaten and the size of the breed.

How much chocolate can a dog eat?
Our advice is not to give chocolate to your dog as even a small quantity can be dangerous, depending on the weight of your dog.
Theobromine doses in the region of 100-150 milligrams per kilogram of bodyweight are toxic to dogs.
For example, if you have a Labrador weighing 30kg, as little as 3000mg of theobromine could be fatal.
You’ll find 3000mg of theobromine in one 500 gram bar of dark or 170 grams of baking chocolate, which is often less than a single bar.
However, for West Highland Terriers weighing just 10kg these amounts should be reduced by two-thirds.

Chocolate and dogs treatment
There is no antidote to theobromine. In most cases, your vet will make your dog vomit. They may wash out the stomach and feed activated charcoal which will absorb any theobromine left in the intestine. Other treatments will depend on the signs your dog is showing.
They may also need intravenous fluids (a drip), medication to control heart rate, blood pressure and seizure activity. With prompt intervention and treatment, the prognosis for a poisoned dog is usually good — even in those who have eaten large amounts.
