What food is best for a dog with chicken allergy and sensitive stomach?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 2 years and 6 months old

My Border Collie-Pit mix, Walker, is allergic to chicken, and I unknowingly fed him dental sticks with natural chicken in them for about a week. We’ve been to the vet to stop the vomiting, stuck to a bland diet and he gets Prilosec every day. Now that that regiment is nearing an end and Walker feels much better, what food should I feed him? Should I look for sensitive stomach blends? What brands are the best? What should I stay away from (OBVIOUSLY chicken)?

Hi there. For dogs with food allergies, I always recommend feeding a prescription hypoallergenic diet such as Hills z/d or Purina HA if possible. With over-the-counter diets, cross contamination with other ingredients is common - so any of these foods may contain small amounts of chicken, even if this isn't listed as an ingredient. So depending on how sensitive Walker is, he could potentially react to almost any OTC food. A prescription hypoallergenic diet eliminates this risk, so you can be sure that he won't have a reaction :)
