The idea that dogs should not eat garlic is relatively recent and, in my fairly extensive experience, quite false. Garlic is a common ingredient in show ring "bait," and, believe me, if breeders had any indication that it was harmful, they would avoid it like the plague. It may be that ingesting extremely high levels of garlic is harmful to dogs, but that would hold true for almost anything.
