About Royal Canin Dermatology For Dogs

Worried About Your Dog’s Skin Health?

Skin health concerns are common and can appear anywhere on your dog’s body. Your veterinarian is the expert on your dog’s health, so you should always consult with this trusted advisor to find the best solutions for your pet. This specialized expertise is why Royal Canin works closely with veterinarians to develop formulas that support skin health.

Common Causes of Skin Health Concerns

Environmental Sensitivities

Pollen, plants and dust are environmental factors that can trigger an immune response in some dogs.

Food Sensitivities

Your veterinarian may recommend a diet elimination trial to help determine if your pet has a sensitivity to certain proteins in his current diet.


Your dog can pick up external parasites such as mites, fleas, ticks and lice from contaminated sources, both indoors and out


Puppies, older dogs, and dogs that have recently been ill may be more susceptible to bacterial infections that can lead to skin health concerns.

How Can Nutrition Help?

Your veterinarian may recommend a Royal Canin Dermatology formula for your dog. These special formulations can:

Aid digestive health by regulating movement through the GI tract and supporting balanced digestive flora

Support the skin’s natural protective barrier

Aid cellular health with a complex blend of antioxidants.

Promote healthy skin and coat by providing long chain omega-3 fatty acids in the diet

Find The Perfect Balance

With a dry and wet feeding routine, dry food supports positive oral health while wet food supports healthy hydration.


Keep your pet's feeding on schedule.  Set your order for Autoship to make sure you always have their veterinarian-recommended nutrition on hand.

Good, but with side effects

Luna has severe food and environmental allergies due to an immune disorder. I spent 6mos doing food trials before I finally got her tested (results confirmed why the food trials didn’t work, she was allergic to EVERYTHING.) I tried Ultamino and HP, settling on HP because of the price since both worked fine. No more hives, no more bloody stool. I was able to get her off the steroids, in combo with doing immunotherapy and using an oral allergy medication. That said, she starting loosing an enormous amount of hair, she would shake and clouds of hair would come out, and she starting getting a lot of dandruff. The vet put her on a probiotic and her hair stopped falling out. She also tends to get a bit constipated, so a little pumpkin helps with that slightly. So I found a way to make it work, and there maybe no perfect answer for puppers like her, but she’s healthier and beautiful and happy.

Hungry Dog

Our dog wasn't eating for weeks regularly so after numerous trips to the vet we switched dog food to Royal Canin HP. Our dog loved it and ate two bowls everyday, and was excited for it! We decided to order on Chewy autoship to make sure we would have his food always on hand since we finally found a food he loved. Our first bag he wouldn't touch, so we had to buy another from our vet. Same thing happened two more times. We would get our chewy order and then our dog wouldn't eat it so had to purchase another bag from our vet. Have spent almost $400 on dog food our dog won't touch. I don't know if it is stored improperly or if coming from third party something is not right with the order. We have since had to order from our vets pharmacy because the chewy, even though same exact food, our dog will not touch.

My 5 month old shih tzu has been struggling with an allergy for 2 months. We have tried all types of food. She will walk up to a bowl, sniff it and walk away. We just got Royal Canin HP delivered yesterday and I have never seen her eat a bowl of food so fast! She loves it! I never thought we would find something she likes and is good for her allergy! This stuff is great and apparently tastes good! Highly recommend. Definitely worth trying.

My vet prescribed this food for you English springer spaniel after battling skin allergies for two years. Sure enough he was right, she was allergic to her dog food/treats. After being on this food for about 4 weeks her redness was fading and hair growing back where she had lost it. Definitely recommend trying a hydrolyzed diet if you are battling skin issues

Chewy is an Awesome Company

I wanted to thanks Chewy for their generosity. I had just purchased a large bag of dog food and 24 case of canned food for my Sampson and sadly had to put him to sleep due to cancer before we could open the the food. Not only did they refund the food which was close to $300 but they asked me to donate it to a shelter. It made me cry. I thought that was so nice. But it didn’t end there. Then I came home from work the next day and they sent me a bouquet of flowers to put a smile on my face. Wow! I am so impressed with this company. Thank you Chewy and Alaira. You made my day during this sad time.

Liked Royal Canin

My dog was having some GI issues and my vet recommended that I changed dog foods. Royal Canin was one of the ones she recommended. I was concerned that my dog wouldn't like it. It has a different smell which I find just nasty but I don't have to eat it. My dog really seems to like it and the symptoms have disappeared.

not working

My vet recommended this for our dog to try to find out if they had food allergies. this dog food is rediculously expensive and it did not help her allergies. furthermore, chewy took a week to verify my vet's prescription. My vet ended up having to call customer service so that they would ship us the food. Waste of money.

Really helps!

This dog food on line is a real help for me, because our store here never has any, and to Dawg because he no longer had a bright red belly! He likes it and since he’s been on it he has not had nearly the itching and chronic redness he had before. The home delivery is easy and I only have to get it from the front door to the food bin instead of out of the car and up the ramp and into the house!

Works for my dog's allergies

My dog is allergic to corn, so this food saved his life since it's soy-based (last I checked). I have no idea why this type of food needs to be a prescription. There are no medications on the ingredient label. The protein is just broken down into much smaller "pieces" which don't trigger the immune system as easily. The price of this food is absolutely insane, and it's increased a tremendous amount since he started on it. Surely, a good company could provide a competitive product at a fairer price. Chewy has the lowest price I can find for it. So if your dog needs it, you'll know it, and this is probably the easiest cheap(est) place to get it. If your dog doesn't need it, save your money and look for a traditional great quality research-backed kibble (I'd suggest avoiding grain-free)

No longer likes food

This food did help immensely with my dogs digestion issues and severe diarrhea. She used to eat the dry food down no problem. I don't know what has changed now she does not like this food she will only eat when she is so hungry that she has to her stomach is completely empty and growling then she will eat this dog food. There have been times where she went almost 2 days without eating because all she was getting was her recommended amount of her prescription dog food. It's a shame it is so expensive and they just raised their price again.
