Garlic and onion can break down a dog's red blood cells, yet so many people continue to feed it to their pets. Don't get me started on the chocolate! I told a friend not to feed her dog grapes; she does it anyway. The vet told her to quit feeding her dog Del Taco French fries (or any fries); she does it anyway. Thank you for posting this list. There are plenty of people who actually love their dogs and will appreciate this information.
in large quantities they can both be toxic to dogs. I have fed our dogs a small dose of garlic with no visible effects other than the lack of parasites, mosquitoes and flies. I guess moderation is the key.
