Can cats eat garlic?The details
Garlic is often recommended online as a natural flea remedy or health supplement for dogs. There is no good evidence it repels fleas, and the dose that might be “safe” varies too much between animals to recommend it.
A clove accidentally eaten by a large dog is unlikely to cause serious harm, but regular small amounts — in table scraps, for example — can build up. Talk to your vet about proven flea prevention instead.
