A small percentage of the pet population suffers from allergies, most of which are not related to diet. However, a small number of pets have sensitivities to food. It's important to know that pet foods do not cause allergies. The risk of developing an allergy is based on the pet's genetic profile, not related to diet. If you believe your dog has a food allergy, it is best to discuss this with your veterinarian to help you choose the right diet for your pet.
