Quantity
Even a single small clove of garlic could cause measurable red blood cell damage in a rabbit. Garlic powder is far more concentrated — a fraction of a teaspoon could be dangerous.
Notes
Garlic bread, garlic butter on vegetables, and seasoned leftovers are the most common accidental exposures. Some rabbit owners unknowingly expose their buns through garlic-containing "natural" supplements marketed for small animals. Always check ingredient lists on anything you offer your rabbit.

FAQ
Q: I saw a website recommending garlic for rabbit health. Is that safe?
A: No. This is a persistent and dangerous myth. Garlic is toxic to rabbits at any dose. Veterinary toxicology data is unambiguous on this. Do not use garlic supplements for your rabbit.
Alternatives
Fresh herbs are the way to go. Cilantro, parsley, mint, basil, and dill are all rabbit-safe and provide the kind of aromatic variety your rabbit actually enjoys.
Risks & Disclaimer
Contact your vet if your rabbit ate garlic in any amount. Do not attempt to use garlic as a supplement, dewormer, or health aid for your rabbit — despite what some online sources claim, veterinary science is clear that garlic is toxic to rabbits at any dose.
