Rated 4.6 out of 5 by 16 reviewers.
Rated 5 out of 5 by Great prescription diet for sensitive skin My dog has been diagnosed with a few autoimmune diseases, food allergies and environmental allergies and this food (along with weekly medicated baths) has greatly improved his skin and reactions. I was currently getting it from our animal dermatologist but found it here on chewy for 20 dollars cheaper and free 2 day shipping! August 3, 2016
Rated 4 out of 5 by Great alternative to other meat protein based foods My little Yorkie has been suffering with skin and coat issues for a couple of years. Then she began having frequent gastrointestinal problems with severe bloody diarrhea. Vets were treating her symptoms but never found the underlying cause. Finally, through my own research, I found another vet who was more proactive and we changed her diet to this RC Soy based dry food. She is also on Budesonide to treat her bowels for a month or so. I eliminated all chicken based food and snacks. The result is my baby Gabi is free of scratching constantly, no oily coat, no swollen feet pads and no IBS! My only reason for not giving 5 stars is that this particular formula does not come in smaller bites for toy breeds. I am hopeful after we wean her off the Budesonide she will continue to eat this food and stay on track. Keeping my fingers crossed! March 29, 2016
Rated 5 out of 5 by My dog LOVES it!! I have a senior citizen dog - he's 15 and has a number of medical conditions including skin allergies and digestion problems. He used to get Hill's Z/D Low Allergen but Hill's stopped manufacturing that (and he isn't able to digest their ultra-high allergen). My vet prescribed Royal Canin Veterinary Diet Hypoallergenic Hydrolyzed Protein PS for him - I was a bit concerned as he is picky with dry food and I knew he liked the Z/D. So it turns out he likes the Royal Canin PS even better! Normally he would eat everyday after midnight (after he would make sure he wasn't getting anything better from me during the day) but now he takes a bit from the PS throughout the day and he ate it immediately when I put it in his bawl. He also reacts to it really well digestion wise. I don't know what Royal Canin puts in it but it works! April 21, 2013
Rated 5 out of 5 by Working great for my food sensitive Boxer My Boxer has severe food allergies and we have tried nearly every brand and type of food. He tolerated the Hydrolized Protein HP formula better than most foods but was still very itchy. His Dermatologist recommended the Hydrolized PS formula in case his sensitivity was to rice. Though we are not quite through the first 25 lb bag, he is doing much better. The itching and chewing has decreased considerably and his feet are clearing up. If you have tried the HP formula and still having itchiness, I'd highly recommend trying the PS formula! It made a huge difference for my dog. March 17, 2016
Rated 5 out of 5 by This food was prescribed by my vet and she has just started it so not sure of results. I think Chewy is one of the most reputable companies that I have dealt with in years. Their customer service is beyond wonderful. I do not buy a great deal on the internet but I would never hesitate to deal with them. I would give them more than 5 stars if I could. Sorry, do not know how to upload photos of my two older greyhounds but they are beautiful :-) December 12, 2015
Rated 5 out of 5 by My dog had a serious itching problem! I have a 16 month old beagle and for several months she had a severe itching problem. She was scratching so badly, she would make her self bleed. The vetenerian told me about change her diet, but I refused to because I couldn't believe she was allergic to all the protein based products. We switched her from chicken, beef, duck, salmon....none worked. This product is soy based, and after feeding it to her 3 days, the itching stopped & her coat began to heal itself! All I gotta say is wow! Pricey, but worth it! My beagle is now enjoying her life without the ITCH! March 1, 2014
Rated 5 out of 5 by Royal Canin PS My dog absolutely loves this product. My allergist changed my girl from HP to PS and there was no transition problem. I have to add Fortiflora to one meal per day as my girl has been known to have very soft melted ice cream like stools. Right now everything seems to be ok as she has been on this since 1/14/15. I have noticed she has a couple extra bowel movements then she had before. Love Chewy's service as well as Royal Canin who has expedited my order within 2 days from my verbal order. January 27, 2015
Rated 5 out of 5 by Great for Digestive Problems This food is absolutely amazing. It was a miracle for my dog! My doberman had chronic diarrhea and bloating for four years. I tried every grain-free food available. She was on several medicines to just manage the condition. My vet suggested we try this as a final effort since nothing else had consistently worked and after one feeding her diarrhea is gone. October 13, 2014
