Chocolate contains a substance called ‘theobromine’ which is toxic to dogs and cats. It’s similar to caffeine and can cause problems with the nervous system, bowels, kidneys and heart.
The darker the chocolate, the more dangerous it is:
- Dark chocolate, cocoa powder, cocoa butter and cocoa beans contain the most theobromine and are very toxic.
- Milk chocolate contains a moderate amount of theobromine so the danger level depends on how much your dog eats.
- White chocolate contains very little theobromine and is a lot less toxic.
Call your vet immediately if you suspect that your dog or cat has eaten chocolate, regardless of the type. Keep the packaging at hand so the ingredients can be checked.
