Dog ate chocolate
If your dog has eaten chocolate, call a veterinarian or animal poison control line with the type of chocolate, the amount, and your dog's weight — the risk depends on all three. Chocolate contains theobromine and caffeine, which dogs clear slowly. Dark and baking chocolate and cocoa powder are far more dangerous than milk chocolate; white chocolate has little theobromine. Acting early, before signs appear, gives the best outcome, so don't wait to see whether your dog becomes unwell.
Go to a vet now if
- Ingestion of dark, baking or cooking chocolate, or cocoa powder
- A large amount relative to your dog's size, or any amount in a small dog
- Vomiting, restlessness, fast heart rate, tremors or seizures
- Any uncertainty about the amount or type
Call a vet today if
- A lick of milk-chocolate or a tiny amount in a large dog — still call your vet to confirm the risk
What to tell the vet
- Type of chocolate (dark, milk, baking, cocoa, white)
- How much was eaten
- When it happened
- Your dog's weight
- Any signs so far
- Other conditions or medicines
What not to do
- Do not make your dog vomit unless a vet tells you to
- Do not assume milk chocolate is harmless in small dogs
- Do not wait for symptoms before calling
What your vet may check
Using the type, amount and your dog's weight, your vet will estimate the theobromine dose and advise. They may induce vomiting if appropriate, give activated charcoal, and monitor the heart, providing fluids and supportive care as needed.
Recovery support after veterinary assessment
Most dogs recover well with prompt care. After the toxic risk has passed, your vet will advise on reintroducing food; any digestive support during recovery is supportive only and used on veterinary advice.
Frequently asked questions
How much chocolate is toxic to a dog?
It depends on the type and your dog's weight. Dark, baking chocolate and cocoa powder are most dangerous because they contain the most theobromine. Provide these details when you call your vet.
What are the signs of chocolate poisoning in dogs?
Vomiting, restlessness, increased thirst, a fast or irregular heartbeat, tremors and, in severe cases, seizures. Signs can take hours to appear, so call early rather than waiting.
My dog ate a small piece of milk chocolate — what should I do?
Call your vet or a poison line with your dog's weight and the amount. Small amounts of milk chocolate may be low risk in a large dog, but it is always safest to confirm.
