Dogs can be allergic to certain foods, just like people. Though some breeds (like golden retrievers and boxers) are more prone to allergic reactions, all breeds are susceptible. Fortunately, many pet food brands have developed dog foods for allergies. They typically fall into one of two categories:

  • Hypoallergenic: Formulated with hydrolyzed proteins (which means the protein is chemically broken down into minuscule parts) to make it harder for the immune system to identify and react to the potential allergen. It sometimes takes a vet visit and a prescription to obtain hypoallergenic foods.

  • Limited ingredient: Contains far fewer ingredients than traditional dog food, so it’s easier to figure out which ingredients cause your dog’s allergies. This is where most pet owners start, especially if the allergy is a new development.

How do I know if my dog has allergies?

According to VCA Ark Animal Hospitals, the most common sign your dog suffers from allergies is itchy skin. Some dogs will scratch one spot to death; others itch all over, all the time. It’s also important to watch for cold-like symptoms, diarrhea and vomiting. The tricky part is identifying the cause of the allergic reaction.

What causes food allergies?

In canines, food allergies usually stem from proteins and carbohydrates in recipes. So, anything from meat to soy to eggs to wheat can cause a reaction. This is why limited ingredient diets are popular. By feeding your pup fewer ingredients, it’s easier to figure out which one is causing the allergic reaction.

One major piece of advice before embarking on this journey and choosing a dog food for allergies: Go all in. If you’re switching to a limited ingredient or hypoallergenic diet, everything you feed your pup needs to meet the diet guidelines. Treats, table scraps, supplements—everything. If your dog ingests anything other than his specific diet, it’ll be impossible to identify the allergen and make him feel better.
