Many dogs with allergies benefit from a diet change to help relieve their symptoms. But with so many dog foods on the market that claim to be good for allergies, how do you know what will work for your dog? We’ve researched dozens of the top dog foods for allergies and give you our top picks.

What’s Causing Your Dog’s Allergies?

The best dog food for dogs with allergies depends on what’s causing your dog’s allergies — food, environmental factors, and fleas are all common triggers for dog allergies. Food allergies can cause gastrointestinal (GI) problems and/or itchy skin. In contrast, environmental and flea allergies typically cause skin problems rather than GI issues. But a healthy diet can help regardless of the cause.

If you’re unsure what’s causing your dog’s allergies, you can give your pup an at-home dog allergy test. These kits test for sensitivity or intolerance to food and environmental factors that develop over time. You send a saliva or hair sample to the company’s lab and get results within a few weeks. You can then share these results with your vet to help further narrow down possible causes.

Best Dog Food For Allergies

We’ve chosen our top picks for prescription options, food allergies, skin-care diets, limited-ingredient dog food, and more. We based our decision on several factors, including the quality and type of ingredients, customer feedback, and the pet food company’s reputation.

Best Hypoallergenic Dog Food (Prescription): Hill’s Prescription Diet z/d Dog Food

Hill's Prescription Diet z/d Dog Food

View on Amazon

Hill’s Prescription Diet z/d is a special chicken-flavored kibble for dogs with skin and/or food sensitivities. This food, which requires a vet’s prescription, is formulated by nutritionists and veterinarians and clinically tested to help dogs avoid skin and digestive symptoms from adverse food reactions. It includes hydrolyzed animal protein and a single purified carbohydrate.

What is hydrolyzed protein? Hydrolysation is a process that breaks a protein structure down into basic amino acids. In this form, the protein is small enough that it’s unlikely to cause an adverse immune reaction.

While it’s not cheap, many customers say Hill’s z/d worked wonders for their dogs’ symptoms and is worth the cost. If you’ve tried out several non-prescription hypoallergenic foods with no improvement, you may want to discuss this diet with your veterinarian.

Best Dog Food For Food Allergies: Open Farm Grain-Free Dry Dog Food

Introducing a novel protein (one that your pup has never had before) to your dog’s diet may help ease food allergies. If you’ve already tried out the common proteins (chicken, beef, pork, lamb), you may want to introduce venison, salmon, duck, or another novel protein into your dog’s diet. These less-common protein sources may not trigger food allergies as much as the usual suspects.

This grain-free dry dog food formula from Open Farm contains pasture-raised venison as its primary ingredient, a mix of nutritious non-GMO fruits and vegetables, and essential vitamins and minerals — all without any artificial preservatives or flavors. It also doesn’t contain grain, corn, or soy that could also cause food allergies.

Open Farm is also a popular choice for pet parents who are devoted to eco-friendly and cruelty-free practices. This company has extremely high standards for humanely and sustainably sourced ingredients. They also offer salmon, whitefish, and many other varieties, as well as dry food with grains, freeze-dried raw dog food, wet food, and treats.


  • Pricing varies by the formula, but to give you a general idea, the beef recipe for a 24-pound bag is $94.99.

Best Limited-Ingredient Dog Food: Canidae Pure Salmon & Sweet Potato

Canidae Pure Salmon & Sweet Potato

View on Amazon

Many pet parents choose limited-ingredient dog foods to help with food sensitivities. Canidae’s pure salmon and sweet potato formula only contains eight key ingredients, with no wheat, grain, soy, or artificial preservatives. It’s fortified with vitamins, minerals, taurine, and a probiotic mix. This is also one of the best grain-free dog foods for skin allergies. Salmon-based dog foods can also be a double blessing for pups with allergies because salmon is less likely to trigger food allergies, and it also contains omega-6 and 3 fatty acids to help ease dry, itchy skin.
