Can Dogs Eat Chocolate?
The short answer · Chocolate for dogs
No. Chocolate is toxic to dogs because it contains methylxanthines (theobromine and caffeine). The darker the chocolate, the more dangerous: cocoa powder and baking chocolate are the worst, white chocolate the least. Use our calculator to estimate the dose, then call your vet or a pet poison line.

My dog ate chocolate. What do I do?
- Stay calm and move your dog away from any remaining chocolate. Keep the packaging if there is one.
- Call your veterinarian, an emergency vet, or a pet poison line right away — before signs appear. ASPCA Animal Poison Control: (888) 426-4435. Pet Poison Helpline: (855) 764-7661. A consultation fee may apply.
- Have ready: your dog's weight, roughly how much was eaten, and when.
- Do not make your pet vomit unless a veterinarian or poison control tells you to.
- Follow the vet's instructions. Early care by the veterinary team can make poisoning less severe.

What it could cost
Treating chocolate poisoning in dogs
Poisoning care usually means an urgent exam, decontamination by the vet team, and sometimes days of monitoring. We publish a price range only after it is checked against named sources — our poisoning treatment and emergency vet visit guide is in verification. A vet bill for this kind of visit is usually built from these line items:
- Exam or emergency consultation fee
- Tests: bloodwork, urine tests or imaging
- Treatment, such as decontamination or medication
- Hospital stay and monitoring, if needed
- Follow-up visits and recheck tests

Frequently asked questions
How much chocolate is toxic to a dog?
It depends on the type and your dog's weight. Merck lists mild signs at about 20 mg/kg of methylxanthines, heart effects at 40–50 mg/kg and seizures at 60 mg/kg or more. A small amount of baking chocolate can be far more dangerous than the same amount of milk chocolate.
Is white chocolate safe for dogs?
White chocolate is a negligible source of methylxanthines (Merck), but it is still fatty and sugary and can upset the stomach or contribute to pancreatitis. It isn't a treat.
How long after eating chocolate will a dog get sick?
Signs usually appear within 6–12 hours and can last up to 72 hours in severe cases (Merck). Call before signs start.
What will the vet do?
If your dog is still well and it's early, the vet team may decontaminate (for example, induce vomiting under supervision) and give supportive care such as fluids, heart monitoring and medication for tremors.
