I have a 10 month old Cavalier Kasey. We got Kasey 6 months after loosing our Sheltie and thinking we could never find one as close and good as she was. Tess was 14 and had become so muchone of our kids. Kasey has fit right in to our family, has been so easy to train, is a pure joy I don't know what we would have done with out him. We currently have Kasey on Eagle premium puppy food. At what age do we change from puppy food to adult food? I have read that corn in food is not good for our Cavaliers. Any thoughts on this? What effect does the corn have? I appreciate any and all feed back.
