Frequently asked

How much chocolate is dangerous for a dog?

It depends on the type and your dog's weight — darker chocolate is far more toxic. Because the safe threshold is low and hard to judge, treat any meaningful ingestion as an emergency and call your vet or a pet poison line immediately.

What are the signs of chocolate poisoning?

Vomiting, diarrhea, restlessness, increased thirst, racing heart, muscle tremors, and in severe cases seizures. Signs can take hours to appear — don't wait for them.
