Interesting...my sister used to have a little silky terrier who was allergic to everything which started about the age of 3 and more or less accelerated over the years until he had to wear a collar all the time to keep from chewing himself bloody. She fed him a diet of cooked meat, kale and a daily multi vitamin--until he became allergic to the vitamin. (IMO, I think the dog was suffering vaccinosis---this was about 20 years ago before the information about over vaccination was widely available. This is part of the reason that I choose to titer instead of just blindly vaccinate.) That being said, I feed my beagle only Fresh Pet because it seems to agree with her digestion--she has always had an iffy, problematic digestive system. Fiona seems to do just fine on a plain, high quality chow once a day but I intend to move her to Fresh Pet for one meal a day, shortly. We also give a supplement of salmon oil once a day with their meal for joints and coats.
