Royal Canin Veterinary Diet Selected Protein PD (Potato & Duck) Dry Dog Food (formerly Hypoallergenic Selected Protein) just might become your best friend's best food. This veterinary-prescribed duck formula helps treat a variety of dermatological and intestinal problems like itchy skin, inflammatory bowel disease, and gastrointestinal upset. Duck is an easily-digested protein not found in most pet foods, reducing the risk of developed digestive problems and allergic reactions. Loaded with a precise blend of antioxidants to help maintain a healthy immune system as well as amino acids that promote a healthy coat and skin, Royal Canin Veterinary Diet Selected Protein Adult PD Dry Dog Food keeps your dog comfortable and healthy from the inside out! 

Key Benefits

  • Complete and balanced, selected-protein dry food diet formulated for dogs diagnosed with food sensitivities resulting in dermatologic or gastrointestinal issues
  • The protein in the diet is provided by potato, duck and hydrolyzed soy, which rarely cause food sensitivities
  • Optimal amounts of B vitamins and amino acids are added help maintain the skin’s natural barrier effect
  • Contains EPA & DHA, long chain omega-3 fatty acids that promote a healthy skin and coat
  • For dogs with sensitive stomachs or food-related allergies

Transition Instructions

We recommend at least a 7-day transition before you begin feeding the new food exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet’s digestive system to smoothly adapt to the new food.

  • PD dry dog food

    By on

    I hope Royal Canin can get its full menu up and running. The vet recommended venison and potato and shortly after we started on that, Royal Canin struggled and ultimately failed to meet the demand. I did not realize I had entered into the world of popular dog food. I did discover that I had entered into the world of a dog food (whether it be venison or duck...which we are currently using) that allowed my dog to eat and gain weight and survive. Thank you to Chewy.com for making dog food that sustains the health of my 75 pound lab accessible and affordable.

  • Great Food!

    By on

    My dog has some severe skin allergies. My current Vet was no longer getting the Royal Canin Special Diet food. So I came across chewy.com. All i had to do was add the food to my cart, put in my vets information for the prescription for the food, and Im not kidding you that I ordered this on a Monday at 11am and the food was delivered on Tuesday afternoon! I couldn't believe how fast it got here. this dog food helps keep my dogs itchy skin under control. He's been on it now for 5 years. I will def be ordering from Chewy.com again!

  • Awesome food

    My baby loves this food. Love at first bite. He was prescribed this food by his vet for IBD. Thought it would be a “RUFF” transition from his other Food. But he went right for it. Great ingredients.

    Thanks to Royal Canin my German Shepherd has gained weight, he is no longer getting sick after a meal, and it is not a struggle to get him to eat anymore. My dog has been on this prescription dog food for over a year and I can finally feel confident to say that his sensitive stomach is being controlled now because of this product. I am very happy and will continue to feed him the potato and duck.

  • My dog loves it!

    By on

    My dog absolutely loves this food! Having been diagnosed with a severe allergy to most dog goods and treats, we found this food through our vet. The local supply seems to be inconsistent and running out is a real issue for our dog since she can't eat regular foods. Shipped right to my door fast, Chewy saved us!

  • Controlled dog's IBD for a decade!

    By on

    I started my dog on RC Potato Duck when she developed an intolerance to chicken-based foods and IBD. It really helped - stopped her diarrhea and she gained back the 12 pounds she lost. She did well on it for ~10 years. Unfortunately her IBD flared up again and I need to try another protein, but I would still recommend this as a truly limited ingredient food.Taking off a star because Royal Canin itself seems to have had production issues over the years. Shipment delays are stressful when the food is the only thing your dog can eat.

  • great stuff

    By on

    Nikki had terrible ear infections for three years. Specialists, allergy shots and meds didn't help. Finally changed to this food and it has been like a miracle! Last two times I have ordered, it is out of stock! Never happened until Chewy was bought out by Petsmart. They want to know what other food I want. None! I have spend several thousand dollars getting my girl well. I do not want to change a thing!

    My dog ate it well at first so I ordered 25 lbs. Then she quit eating it. Back to cooking for her - wish I had my $ back.
