Why
Garlic belongs to the Allium family and is more toxic than onion. It damages red blood cells, and the signs can show up days later.
What to do instead
- Do not feed garlic in any form: raw, cooked, powder or in sauces.
Warning signs
- Symptoms can be delayed, so watch your dog for several days and call a vet if it ate garlic.
If your dog ate garlic
- 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 seasonings and drinks: quick answers
| Food | Verdict | Short answer |
|---|---|---|
| Cinnamon | Avoid | Best avoided. Cinnamon is not toxic in small amounts but can irritate the mouth and stomach. |
| Alcohol | Toxic | No. Alcohol is absorbed fast and can be deadly for dogs. |
| Coffee and caffeine | Toxic | No. Caffeine is toxic to 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.
