What I don't understand about this discussion is why you wouldn't feed your dog meat.
I haven't seen anyone on here asked to justify their decision to feed their dogs meat, however plenty of people have asked why you wouldn't.
So, can the vegetarian feeding people tell me why they don't actually feed meat? Other than the usual I don't like it response, because this isn't about you, it's about your dog and what they would prefer.
Cavalier - I feel very sorry for your dog, my cavalier loves nothing more than getting a juicy marrow bone and spending a few hours attacking it. I don't particularly like getting it out of the bag, granted, however I also don't like picking up dog poo on our daily walks - it's just something that has to happen if I want to own a dog.
