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.

About Royal Canin

What sets Royal Canin apart is their close collaboration with veterinarians. Through these professional partnerships, they strive to learn everything they can about pet health, including how different formulas perform for different breeds, sizes, lifestyles and therapeutic conditions.

my boy loves it

My guy has an autoimmune disease so requires a Hydrolyzed diet. He did not like the Purina Pro Plan Hydrolyzed so we switched to this and he LOVES it. scarfs it down.

Approved by my picky eater

My dog has been suffering with GI issues for months and we’ve been taking him to the ER and vet appointments to find out what it’s going on. His vet suspects he might have either IBD or food allergies. He does not like kibble and we tried every type of dry food before without success. His vet prescribed the Royal Canin hydrolyzed food as a food trial and he ate it like if it was a piece of chicken! He loved the food and I am so relieved! Hopefully this food will help him getting his mucousy diarrhea and stomach issues under control! Win win!

She loves it!

I was afraid she wouldn’t like it bcz the vet stated that it doesn’t have much flavor and had originally said to choose a meat she hadn’t had before like venison, rabbit or alligator but Royal Canin isn’t making the wet food in those flavors right now and when I emailed them they stated they were not currently making it and wasn’t sure when they would start making it again. She has a thickening in her intestines so she doesn’t break down protein in her intestines. She was so so sick I thought I was going to lose my baby. I got this one, wet and dry and she loves both and I believe it saved her life. She now wants me to throw her squeaky toys again! I’m so happy she’s doing better.

Good choice

Our vet recommended this for our Boston who has a lot of allergies. Expensive but seems to help with digestive and skin issues.

Only as good as it can be

What's the point of having autoship when the customer has to keep tabs on why it has never been shipped

answer to my prayers !

My 10 year old dog had been suffering from stomach issues for years… after multiple vet visits(ultrasounds, labs, medications and several diet changes) we landed on this food and it has worked wonders! Maya used to pant, pace and crawl all over us when her stomach issues were flaring up but ever since we switched to this food her stomach flare ups and behavioral issues have all cleared up! I was even able to eliminate half of the medication she was on for stomach and anxiety!

Not as good as the Hydrolized HP

My mastiff mix Buddy has been on the RC Hydrolized HP for probably 5+ years and has done really well after getting inflammatory bowel and Cutaneous Histiocytoma skin flare ups starting around age 4 (he's now 9.) In fact my boxer dog has also been on it with him and both of them rarely get any problems, gas, etc. Buddy seemed to have an attack of pancreatitis or something similar about 6 months ago and now we have to be really careful. Doesn't seem like he can tolerate much red meat anymore which he used to love! :/ We ordered the PS version by accident when they were having a lot of supply chain issues with the food - FRUSTRATING!!! We had relocated during mid 2020. Driving all over trying to locate his HP food - sooo difficult. Chewy's shipping is great as we get the 25 lb bags. So...I mixed in the PS food. It's a totally lighter different color. He will eat it but I don't think it's agreeing with him as well. Just checked all the ingredients. HP version is a bit higher in protein and fat it looks like. HP has brewer's rice, chicken fat and beet pulp. the PS has Potato and coconut oil (no rice or chicken as far as I can see) so those are the differences. I have not had an allergy panel since he's always done so well on the HP but maybe we will as I'm curious as to whats' causing his discomfort lately.

Dog didn't like

My pup is on a food trial to figure out what is triggering his lupus. He hated this food. Wouldn't touch it. Not saying it's a bad product...but my pup hated it
