FAQs
My dog ate a small amount of chocolate β should I be worried?
It depends on the type and amount. Dark/cooking chocolate is far more toxic than milk chocolate. Even a small amount of dark chocolate in a small dog is an emergency. As a general rule, always contact your vet or the Animal PoisonLine (01202 509 000) β they can calculate toxicity based on the type of chocolate, amount, and your dog’s weight. Never wait for symptoms to appear.
