Feeding a Dog with Food AllergiesMy dog can't have beef, milk, kelp, white potatoes, or brewer's yeast. He is also sensitive to salmon, bison, chicken, peas, lamb, turkey, and eggs. I had him on kangaroo on advice from the vet, but he doesn't care for it and it's 75.00 a bag. I have two other dogs so I need them all to be on the same thing. He is all red and itchy and is also sensitive to some outdoor things I can't control.
