Can dogs eat chocolate?
No, dogs should not eat chocolate, including milk chocolate, dark chocolate, baking chocolate, and cocoa powder. Theobromine and caffeine can cause vomiting, a racing heart, tremors, or seizures, so call a poison hotline the same hour and bring the wrapper.
Portion and preparation
None. Baking chocolate and cocoa powder are more dangerous than milk chocolate because they contain more theobromine; there is no safe home portion in ounces (grams), and a smaller pet can be harmed by less than a larger one. Powder, broth, and baked goods count the same as the plain ingredient.
Why this matters chemically
Theobromine and caffeine are methylxanthines that dogs, cats, birds, and small pets clear slowly. Baking chocolate and cocoa powder contain more theobromine per ounce (per gram) than milk chocolate, so a small missing piece is more dangerous in a small animal.
What clinical signs can appear?
Signs vary with the amount eaten, the animal's weight in pounds (kilograms), and how much time has passed. The list below is what clinics commonly ask about. It is not a checklist that rules disease in or out for one animal.
- Vomiting
- Restlessness and a fast heart rate
- Tremors
- Seizures in severe cases
What if this was eaten?
Call a poison hotline or emergency clinic with the chocolate type, the amount missing, the dog's weight, and the time eaten. Remove leftovers and wrappers. Do not induce vomiting, and do not give milk, oil, salt, or hydrogen peroxide unless a veterinarian tells you to; bring the package to the clinic.
Which agencies regulate this advice?
