If your furbaby is constantly itching, vomiting, and/or having diarrhea, then they may have a food allergy. A food allergy happens when a dog’s immune system overreacts to an ingredient that isn’t actually harmful. The most common food allergies in dogs are beef, chicken, dairy, eggs, soy, and wheat gluten.
The most accurate and most affordable way to find out which foods your pup is allergic to is through an elimination trial, wherein a particular ingredient is removed from their diet for 8 to 12 weeks. If your dog’s allergy symptoms go away during the trial, then you’ve found the culprit. If they don’t, repeat the process with another ingredient.
Once you know what your dog shouldn’t be eating, the next step is to choose a hypoallergenic dog food so that their symptoms don’t come back. A hypoallergenic diet can be:
- A hydrolyzed protein diet, where the protein molecules are broken down to a size so small it becomes invisible to your dog’s immune system.
- A novel protein diet, which includes an uncommon protein source that your dog hasn’t consumed before, such as duck, rabbit, or bison.
- A limited ingredient diet, which contains a minimal number of ingredients and often a novel protein.
Let’s take a look at some of the best hypoallergenic dog foods on the market. Some of the foods featured in this guide have been personally recommended by Dr. Georgia Jeremiah, pet nutrition expert and one of Wag!’s veterinary consultants!

What pet parents say about Canidae PURE
"What I love most is he barely sheds now. I am happy with this product. The only reason why I didn't give it 5 stars is because I do have to top the kibble with a tasty treat, like salmon skin that we don't eat when [making] our salmon in order for him to eat it. He won't eat the kibble on its own."
