Product Reviews
Royal Canin Veterinary Diet ® Canine Multifunction Urinary + Hydrolyzed Protein dry dog food is rated 4.8 out of 5 by 53.
Rated 4 out of 5 by from Helpful food My dog has major food allergies and started on the HP a few years ago. He started to produce urinary stones and had a cystotomy so my vet researched and found this food and I immediately changed him. He is still building urinary crystals and stones but at a slower pace. I have tried to cycle him back to just SO but his allergies get really bad. For pet parents who are in a similar situation as i was, this food is a gift from god. My only complaint is it is hard to get in the Florida Keys. I wish that sites like foster and smith, pet meds or any other rx sources would also sell this multifunction. i

Rated 5 out of 5 by from Hooray. Finally a dry food our dog can eat! Our 9 year old Bichon has a long history of food allergies as well as calcium oxylate crystals and stones. He has had bladder surgery twice. Following his last surgery, Max was on a strict diet of canned Royal Canin Urinary SO. I was concerned about how a diet of "wet" food only would affect his teeth, but we had no choice. When our vet told us about Royal Canin's multifunction urinary plus hydrolyzed dog food, we jumped at the chance to try it. So far, no increased allergy problems and he really likes it. I alternate one meal of canned and one meal of dry food daily. Thanks Royal Canin for giving Max a little variety and giving us some peace of mind. P.S. He had his teeth cleaned recently and other than a minimal amount of plaque, his teeth are fine.

Rated 5 out of 5 by from The BEST Hypoallergenic food that helped my dog! I worked for a vet and our dog was diagnosed with Inflammatory Bowel Disease, which is normally caused by a food allergy. We tried another prescription diet and while she no longer vomited, she was still losing weight like crazy. After lots of research, Royal Canin Hypo HP was recommended. She's been on this food for over 5 years now with minimal flare-ups, healthy coat, and maintained a perfect weight. HIGHLY recommend!

Rated 5 out of 5 by from One of a kind My dog has had food allergies for her whole life. She was diagnosed with chronic crystals in her urine that we’re not clearing up with antibiotics. The doctor recommended switching her to this food and it took care of the crystals and she has not had any more urinary tract infections or developed any stones. This is the only food on the market that is for urinary care for dogs with food allergies. Awesome product and my dog loves it! So thankful I found this food.

Rated 5 out of 5 by from Perfect for our little guy We’ve used the HP food for a few years & then switched to this one after our precious pooch had bladder stones. He loves royal canin food. We fed him canned Royal canin food after surgery & he loved that too! This food is actually cheaper than normal pet store food when you price it per day. Ive recommended it to several friends and family. Compared to other foods i love the smell of this stuff, no weird meaty fishy smell. When we visit friends, his “girlfriend” tries to gobble up his food instead of her own, so everyone loves it. Diego gives it 2 paws up!

Rated 5 out of 5 by from Great for skin & crystals in urine My dog needed to go on the S/O diet due to crystals in her urine. After several years , the crystals were gone , but her weight & coat started to decline. We switched over to the urinary + HP and within months, she gained her weight back , and her skin looks great. As I am a vet tech , this is one of my first go to foods now for my clients that have pets exhibiting the same symptoms my dog did. I'm very happy to have found this food !
