Why
Chocolate's methylxanthines affect the heart and nervous system. The darker the chocolate, the more toxic: cocoa powder and baking chocolate are the worst, white chocolate the least.
What to do instead
- Never share chocolate. Use the chocolate toxicity calculator if your dog got into some.
Warning signs
- Signs usually start within 6 to 12 hours: vomiting, diarrhea, thirst, restlessness, a racing heart, tremors and seizures.
- Call your vet or a poison line right away.
If your dog ate chocolate
- Note how much your dog ate and when, and keep any packaging.
- Call your vet, an emergency clinic, ASPCA Animal Poison Control ((888) 426-4435) or the Pet Poison Helpline (855-764-7661).
- Don't make your dog vomit unless a vet tells you to.
Other sweets: quick answers
| Food | Verdict | Short answer |
|---|---|---|
| Ice cream | Avoid | No. Ice cream is sugary dairy, and some flavors are toxic. |
| Honey | Small amounts | Yes, a tiny amount. Honey is mostly sugar. |
| Xylitol (sugar-free sweetener) | Toxic | No. Xylitol is extremely dangerous for dogs. |
Rules for any new food
- Plain is the rule: no salt, butter, oil, onion, garlic, sugar or sweeteners. Most of the danger in human food comes from what is added to it.
- Keep all treats under 10% of your dog's daily calories (WSAVA). The rest should come from a complete dog food.
- Check labels for xylitol, raisins, chocolate and macadamia nuts, which turn up in baked goods, snacks and spreads.
- If your dog has a health condition, such as diabetes, pancreatitis or kidney disease, ask your vet before adding any new food.
