are all cavaliers so picky when it comes to food? My puppy Charlie who's five months won't eat anything that "dog" on the lable! I have to mix his food with gravy from dinner. He will sometimes eat it if I hand feed him. I tried to mix his dry food with all different kinds of canned food too like benefit or purina. He has beneful, purina one, wellness and iams dry food and won't eat it! What did you guys feed your puppies?? Thanks
