I have a black lab that will be 10 years old. He gets very serious allergies in the fall and winter and I have to be careful of what I feed him. Wheat gluten and like products are the worst. At first I thought this food was going to work, but the dog has gas so bad after every meal that it makes family life miserable. His buddie, the beagle is gaining too much weight also. They really like the taste though.
