Does a raw diet help with weight gain? I have a pitty too that I can't get to gain weight. She did fill out pretty good but we got a new dog and now she stays pretty skinny. I have been feeding her can food now to help but it is not. Also she gets pretty bored with food but I have her on chicken soup and I like it for the price and food, so I don't want to keep changing her food to keep her happy because I can't aford better food but I don't want to give her what petstores sell. Is it a lot more to feed raw? I have 3 about 50 pounds each dogs.
