Best dry dog food for allergies

Purina Pro Plan Veterinary Diets HA

Available for $50.99

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 Ivana Crnec, DVM, a veterinarian at veterinarians.org. 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 Whitney Miller, DVM, chief veterinarian at Petco. The food comes in 6-, 16.5- and 25-pound bags, and in salmon, chicken and vegetarian varieties.

Pros

• Known throughout the industry as the best dog food for allergies
• Easily digestible, even for senior dogs

Con

• Requires vet authorization

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.

What to consider when buying dog food for allergies

You have several things to consider when selecting the best dog food for allergies, according to Dr. Crnec. In particular, look for:

• A limited number of ingredients
• High-quality (preferably organic) ingredients
• Hydrolyzed or novel proteins
• AAFCO-approved formulas
• No cheap fillers and artificial additives
• No unspecified ingredients
• Brand reputability and trustworthiness
• Positive feedback from other customers

Plus, the FDA is investigating the potential link between canine dilated cardiomyopathy (DCM) and certain grain-free dog foods. “If your dog is currently on a grain-free diet and has no history of heart issues, your veterinarian may recommend monitoring your dog’s heart health closely and considering a diet change if any concerns arise, ” says Lindsay Butzer, DVM, a small-animal veterinarian and PetMeds partner. “If your dog has already been diagnosed with DCM or another heart condition, your veterinarian will likely recommend a diet change and appropriate treatment.” While the FDA alert should be taken seriously, Dr. Butzer also recommends working closely with your veterinarian to ensure your dog’s diet is meeting their individual needs and promoting optimal health.

FAQ

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 Dr. 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 Amber Karwacki, DVM, of Heart + Paw pet-care 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,” Dr. 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 Dr. 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.
