I have a great dane puppy that is about 5 months old. He has had several skins rashes in the past few months and now he is starting to loose a little hair around his forehead. Our vet suggested an allergy test, but I read that those aren’t always accurate. We have always feed him Purina Pro Plan large breed puppy, but I would like to try to switch his food before we do the test. Do any of you have any suggestions?
