Like humans, dogs have allergies, too. One of the most common culprits? The food you feed them. But before changing your dog’s diet or investing in some healthy dog treats, you must determine exactly what your dog is allergic to. This is best left to a vet—in fact, many of the best dog foods for allergies require vet authorization as a stopgap to ensure your pet gets the proper nutrition.

But once you figure out why your fur baby is suffering, you must take swift action. “If dealing with a potential food allergy, an immediate diet change is mandatory,” says Ivana Crnec, DVM at veterinarians.org. We consulted with her and several other vets to select these picks.

Purina Pro Plan Veterinary Diets HA

Purina Pro Plan HA received votes from two of the vets we interviewed as their top pick. “This dog food features a single hydrolyzed protein source and a single carbohydrate source,” says Crnec. The process of “hydrolyzing” the protein breaks it down using enzymes to the basic components of amino acids and peptides. This means that the food is easily digestible and promotes healthy nutrient absorption, she says.

You may feed Purina Pro HA to dogs of any size—small, medium and large breed dogs—as well as senior dogs, because the hydrolyzed protein suits any dog that has trouble with digestion, says Dr. Whitney Miller, DVM, MBA, DACVPM, chief veterinarian at Petco. The food comes in 6-, 16.5- and 25-pound bags, and in salmon, chicken and vegetarian varieties.

It contains only nine ingredients, including salmon, oatmeal and wholesome grains—all human foods that are great for dogs—and leave out corn, wheat, soy, artificial flavors, colors or preservatives.

“It’s enriched with healthy fats, antioxidants and probiotics to strengthen the immune system, boost digestion, and promote skin and coat health while supporting growth and development,” Crnec says. It comes in 4-, 12- and 22-pound bags.

The food also contains fish oil and flaxseed, both “healthy omega fatty acids that are vital for skin and coat health,” she says. Plus, the food is grain-free and reviewers report their dogs enjoy the taste. It comes in 6- and 22-pound bags—once you get your vet’s authorization.

As shopping experts, our only job is to help you find a winning product.

Then we research the features that speak to the product’s quality, taking advice from industry insiders and subject matter experts on what makes a product a smart value (or worthy of a splurge). Finally, we do the work of combing through user reviews to see how real people interact with the product, and if it stands up to the test.


What are common allergies for dogs?

Beef, wheat and chicken are common food allergens for dogs, explains Miller. “However, many times, allergic dogs have multiple factors contributing to their allergies, not just food,” she says.

Environmental irritants like grass, pollen and plants can cause similar allergy symptoms in dogs as those that humans experience. Within the home, your dog may be sensitive to dust, mold or dander. Environmental allergies can also manifest as ear infections or gastrointestinal symptoms in dogs.

“Finally, if your dog has a flea allergy you may see increased skin irritation around bites, so keeping your pet on pest prevention is critical,” she says.

What are common symptoms of allergies in dogs?

The number one most common symptom of allergies in dogs is itchiness. “It can be localized to one area of the body or generalized (affecting the entire body),” says Crnec. Other allergy symptoms in dogs are obsessive paw licking/chewing, hives, red and inflamed skin, diarrhea, vomiting, sneezing and frequent ear infections.

The most common symptoms of food allergies to look out for are itching and GI upset, according to veterinarian Dr. Amber Karwacki, DVM, of Heart + Paw petcare centers. Other symptoms to look out for: irritated eyes, a runny nose hair loss and ear infections.

“If food allergies are suspected, your veterinarian will either recommend an elimination food trial to determine what your dog can eat or a food allergy [blood] test,” Karwacki says. She warns against relying on seemingly convenient “at-home” tests and panels using hair and saliva samples. “Studies have shown that commercially available tests marketed for environmental and food allergies are inaccurate,” she says.

What foods are best for dogs with allergies?

There is no universally best dog food for allergies. But generally speaking, dogs with allergies need formulas with a small number of high-quality and carefully selected ingredients.

“It all depends on the type of allergy and the dog’s nutritional needs, including age and lifestyle,” says Crnec. “For some dogs, the best food features hydrolyzed protein, and for others, novel proteins from animals the dog has never tasted before, like venison, rabbit, bison, kangaroo or duck.”

Is wet or dry food better for dogs with allergies?

Neither one is better than the other for allergies. “The key is the ingredients present in the food,” says Karwacki. However, if you have a picky eater or a senior dog with sensitive or missing teeth, your pup may find wet food more palatable.
