We are asked this question a lot, what food can I give my dog if my dog is allergic to chicken. Very often dog food is sprayed with poultry fat to make it tastier, this is fine if your dog is not allergic to chicken. You may be buying a dog food that you think has no chicken in it, but not realising that its possibly got chicken fat sprayed on it. Also, take a look at the treats you are giving them, is chicken mentioned somewhere in the ingredients?
Our Happy Nose Lamb and Rice recipe from our Naturals range does not contain chicken, its composition is 34% Lamb made up of 25% dried lamb, 4% freshly prepared lamb, 3% lamb fat and 2% lamb gravy.
