Thanks everyone for the concern that I might be killing my dogs. Dogs are omnivores, which easily allows them to eat all sorts of stuff. I've talked to my vet (who is a hunter and omnivore himself) and he is confident that a vegan diet is healthy. He said that Westies (Darby) are prone to skin allergies and a vegan diet is BETTER for him.
Look at him!! Tell me he doesn't look happy!!!!!
