Common Questions

How much chocolate is dangerous for a dog?
It depends on the type of chocolate and your dog's size. As a rough guide, 1 ounce of dark chocolate per pound of body weight is potentially lethal. For milk chocolate, it takes a larger amount. Even sub-lethal doses can cause vomiting, diarrhea, and discomfort. When in doubt, call your vet.
Is white chocolate toxic to dogs?
White chocolate contains very little theobromine, so it's rarely dangerous from a toxicity standpoint. However, its high fat and sugar content can still cause pancreatitis or stomach upset, especially in smaller dogs.
My dog ate chocolate 12 hours ago and seems fine — should I still worry?
Most symptoms appear within 2-4 hours, but theobromine is absorbed slowly and effects can be delayed up to 12 hours. If it's been 12+ hours with no symptoms and the amount was small, your dog is likely okay. Call your vet for peace of mind.
