The 10 Best Dog Foods for Skin Allergies

1. Royal Canin Ultamino – Best Overall

Royal Canin Ultamino is the best overall dog food for skin allergies. The food is a hydrolyzed protein diet, so the molecules are much smaller than what normally triggers a food allergy. Ultamino also features a blend of fiber to help promote gut health, promoting a healthy immune system. This food only comes in the chicken recipe, so if your dog is allergic to chicken, this will not be the right choice for them. This food is also a bit on the pricey side.

2. Purina ProPlan Sensitive Skin and Stomach Salmon & Rice Formula – Best Value

Looking for a non-prescription dog food to get your dog's skin allergies back under control? Our pick for the best non-prescription food is Purina ProPlan Sensitive Skin and Stomach. This food comes with one of several protein sources, so if your dog has a food sensitivity, you can try to avoid it without going the route of hydrolyzed diets. Some reviewers of this food noted the recipes might have changed, and their dogs have had some digestive issues with the revised recipe.

3. Royal Canin Selected Protein PR – Premium Choice

The prescription Royal Canin Selected Protein PR is an excellent choice. It is one of the best novel protein diets available. It features a skin support formula, including EPA and DHA omega-3 fatty acids, to promote a strong skin barrier. This is also a limited-ingredient recipe, which is another reason why it is a good choice for dogs with sensitive stomachs. Some people who have used this recipe for a few years noted that the formula changed recently, which impacted their pup’s digestive health a bit.

4. Purina Pro Plan Puppy Sensitive Skin & Stomach Salmon & Rice Dry Dog Food – Best for Puppies

Puppies are not immune to skin issues, so selecting the right food for them is important. Purina Pro Plan Puppy Sensitive Skin & Stomach has salmon as the first ingredient, which is essential for growing puppies. Rice is a more easily digestible grain, and barley adds needed fiber to their diet to help maintain a healthy digestive system. A few people noted that their pups developed minor digestive issues after eating this food for a few days.

5. Purina ProPlan Veterinary Diet HA

Purina ProPlan Veterinary Diet HA is a typically more budget-friendly hydrolyzed protein diet. It ranks as our runner-up for Best Overall Dog Food for Skin Allergies. It has three formulations: a chicken, salmon, and vegetarian recipe. As a hydrolyzed diet, it tends to be readily digestible. The inclusion of coconut oil is beneficial because it promotes mental sharpness for older adults and seniors. Some people noted that this was a bit of a pricey option.

6. Hill's z/d for Food Sensitivities

If you need a canned food for your dog, Hill's z/d is where you need to look, and it is the best option for Canned Dog Food for Skin Allergies. While there is the newer low-fat formula, the "OG" z/d is a terrific option for dogs that don't like or can't eat hard kibble. This formula has just one carbohydrate source and has chicken liver as one of the star ingredients. A few people noted the consistency was not always consistent.

7. Hill's i/d Low Fat Digestive Care

The newest diet in this list, Hill's i/d Low Fat Digestive Care, is a beautiful option for dogs with both food allergies and gastrointestinal issues like pancreatitis, so much so that it's considered our Best Overall Dog Food for Skin Allergies for Dogs With Gastrointestinal Problems. It also features a proprietary blend to help reduce the risk of certain bladder stones. This food is a little on the expensive side.

8. Blue Buffalo NP Alligator

Many dogs worldwide choose alligator as a novel protein source, so Blue Buffalo NP Alligator makes our list of high-quality foods for dogs with skin allergies. This prescription diet helps control skin allergies when your dog is sensitive to many proteins that can cross-react. Some people felt this food was a bit expensive. However, this is often the case

9. Royal Canin Skintopic

Royal Canin Skintopic is unlike many of the foods on this list designed to combat skin issues related to food allergies. This food is designed to help alleviate your dog's signs of environmental allergies or atopic dermatitis. It is recommended for dogs suffering from environmental allergies.

10. Hill's Derm Complete

Hill's Derm Complete offers two benefits: it helps support the skin against environmental allergens while also helping with food allergies. This recipe is designed to improve night scratching, helping with their sleep quality. This is not the best recipe for dogs who are overweight or are prone to weight gain

Buyer's Guide: Choosing the Right Dog Food for Skin Allergies

Finding the right food for your dog is challenging at the best of times, but it's especially tough when your dog has allergies. How do you know which to try? For starters, a veterinarian is a great tool to help you pick the right food for your dog, but the most challenging part will be the food trial.

If you are concerned about the health and well-being of your pet, seek veterinary advice for the best course of action.

What Is a Food Trial?

Food trials can be more complicated than finding the right food. Your dog will be eating one food—with nothing else—for at least 8 to 12 weeks in most cases. For the most part, treats count in this. That means unless your vet prescribes a treat for you to offer, you can't even add an egg to your pup's food bowl. You're paying a premium for these foods, so sticking out the diet trial is worth it. At the conclusion of your dog’s food trial, your veterinarian will likely have you "challenge" your dog with their old food to see if signs of allergies return. You may not need to do a traditional food trial with foods like Skintopic and Derm Complete, but you'll want to stick mainly with the prescription food, at least in the beginning. You and your vet must choose between a novel protein and a hydrolyzed protein diet. A novel protein diet is one in which the protein source differs from what your dog has ever had. This feature is the most important because dogs are usually sensitive to the protein source, not the carbohydrate source.

You must list everything your dog has eaten so your vet can suggest an ideal novel protein diet. With hydrolyzed diets, the protein is broken down into incredibly tiny molecules, so your dog shouldn't react to them. Typically, the actual protein source doesn't matter for these, so even if your dog is allergic to chicken, a chicken-based protein should be fine. Hydrolyzed protein diets are usually more expensive than novel protein diets. They are usually less palatable, so your picky pup might do better with a novel protein like venison, kangaroo, alligator, or rabbit. Unfortunately, numerous diets now utilize proteins that used to be reserved for prescription diets, so you might have trouble finding a novel one.
