Can dogs eat chocolate?
No — chocolate is toxic to dogs. Dark and baking chocolate are the most dangerous because of their theobromine content; milk chocolate is less potent but still risky. Call your vet or the ASPCA Animal Poison Control ((888) 426-4435) immediately if any amount is eaten.
Chocolate contains theobromine, which dogs metabolize too slowly to safely process. Even small amounts can cause vomiting, heart issues, or seizures. This page covers what to do right now — use our chocolate-toxicity calculator for dose-specific risk.
Watch out for
- Theobromine is the main toxin — dogs process it 3× slower than humans.
- Dark and baking chocolate are most dangerous (roughly 5× more theobromine than milk chocolate per gram).
- Milk chocolate is still toxic at higher doses — a 10kg dog can react to ~60g.
- White chocolate is low in theobromine but high in fat/sugar — not "safe", just less acutely toxic.
- Symptoms can take 6–12 hours to appear — by the time a dog looks sick, theobromine levels are peaking.
Frequently asked
My dog just ate chocolate — what should I do?
Call your vet or the ASPCA Animal Poison Control ((888) 426-4435, 24/7) immediately. Have your dog's weight, type of chocolate, and amount eaten ready. Our chocolate-toxicity calculator gives a quick dose estimate while you dial.
How much chocolate is dangerous for dogs?
Mild toxicity starts around 20mg of theobromine per kg bodyweight; severe above 40–50mg/kg; potentially fatal above 60mg/kg. A 10kg dog can show signs from ~20g of dark chocolate or ~60g of milk chocolate. Baking chocolate is worst.
What are the symptoms of chocolate poisoning in dogs?
Early (6–12h): vomiting, diarrhea, restlessness, excessive thirst. Moderate: rapid heart rate, tremors, agitation. Severe: seizures, collapse, heart arrhythmia. Symptoms can last 24–72 hours.
Is white chocolate safe for dogs?
Less dangerous than dark or milk because of low theobromine content, but not safe — high fat and sugar can trigger pancreatitis, especially in susceptible breeds. Skip it.
Can dogs eat cocoa powder?
Cocoa powder has the highest theobromine concentration of any chocolate product. Treat any ingestion as an emergency — even a teaspoon is a meaningful dose for a small dog.
