Garlic is toxic to dogs — more potent than onion

Garlic belongs to the Allium family (along with onions, leeks, and chives) and contains thiosulfate compounds that damage dogs' red blood cells. Garlic is actually considered 3-5 times more toxic than onion on a per-weight basis. All forms — raw, cooked, powdered, and dehydrated — are dangerous. Garlic powder is especially concentrated.

Common Questions

How much garlic is toxic to dogs?
Studies suggest toxicity can occur at around 15-30 grams of garlic per kilogram of body weight. However, toxicity is cumulative — repeated small doses over days can also cause problems. A single clove of garlic weighs about 3-7 grams. As a rule, no garlic should be intentionally given to dogs.
Is garlic powder more dangerous than fresh garlic?
Yes, garlic powder is more concentrated than fresh garlic — a small amount of powder contains the equivalent of multiple fresh cloves. This makes garlic powder, garlic salt, and dehydrated garlic particularly dangerous. Check ingredient labels on food before sharing with your dog.
Some dog supplements contain garlic — is that safe?
Some pet products include very small amounts of garlic, claiming flea-repellent or health benefits. The evidence for these benefits is weak, and most veterinary organizations advise against giving garlic to dogs in any form. Consult your vet before using any garlic-containing pet product.
