Dog owners, what do you feed your dog? My friend adopted a 5 year old puggle a couple months back and has been feeding him science diet, but everyone is telling her to switch because science diet is crap. She's looking for a healthy dry food, but nothing she has to go to a special store for (I suppose this means she'll go to petco, but not a health food store or something). My dogs eat canidae but she doesn't want that because not many stores carry that around here. So, what is a good healthier brand of dog food at petco, in your opinion? Please share any experiences about certain foods.
