Chocolate harmful for Dogs
Chocolate contains an alkaloid called “theobromine” which is in the same family as caffeine and is a type of stimulant.
Dogs and certain other animals, such as horses and cats, cannot metabolize theobromine as quickly as humans can. Some of symptoms of chocolate consumption such as a rapid heart rate, can ultimately be fatal for a dog.
So how much chocolate is too much for a dog?
That depends on the size and age of the dog, as well as what type of chocolate was consumed. The larger the dog, the more theobromine they can handle without dying.
