Can Dogs Eat Garlic Powder?

Garlic powder is worth taking even more seriously than fresh garlic, because drying and grinding it concentrates the toxic thiosulphate compounds into a much smaller volume. It's an easy ingredient to overlook, since it's used in all kinds of seasoning blends, marinades, and even some homemade dog treat recipes that mistakenly assume a small amount is harmless. The damage it causes to red blood cells builds up gradually, so a dog can seem completely normal for a day or two before weakness or pale gums start to show, which makes it easy to miss the connection to something eaten days earlier. If you know your dog has eaten food seasoned with garlic powder, it's worth calling your vet proactively rather than waiting to see if symptoms appear.
