Is garlic bad for dogs?
Garlic is a member of the same family as onion, but there are significant differences between garlic and onion. Onions can trigger hemolytic or “Heinz factor” anemia (where circulating red blood cells burst) through its high concentration of thiosulphate. With onions, a single generous serving can cause this reaction. Garlic simply DOES NOT CONTAIN THE SAME CONCENTRATION of this compound! In fact, it is barely traceable and readily excreted (not stored in the body). One source says that for garlic to be dangerous to your dog, you would for garlic to be dangerous to your dog you would have to feed them a couple of whole bulbs a day on an ongoing basis.
