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.

The prescription Royal Canin Selected Protein PR is an excellent choice. It is one of the best novel protein diets available.

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.
