I haven't been giving him raw food...he's only eaten the purina pro plan puppy chow and then the chicken and rice I've been cooking. I have looked at special diet kibble and it's expensive which is why I decided to cook his food...although that is pretty expensive as well, so kibble might be the way to go. I'm working with my vet right now to see what he thinks. I faxed him a copy of everything we give my puppy as well as his general condition. I think they may be thinking about putting him on a special diet to see if that helps. I'll have to look at my options and see which one is the most cost effective and health consious one. I know there are several brands to choose from that are holistic and hypoallergenic. Thanks for your post :)
