Customer Ratings & Reviews

Rated 4.6 out of 5 by 75 reviewers.
Rated 5 out of 5 by Thank you Purina for making this dog food Our 2 Shih Tzus have terrible allergies. Thanks to our vet for recommending this dog food. Have gone thru just about every expensive dog food on the market to help my babies not scratch themselves to death. The medication has helped, but with this right dog food, I have not had to give them their medication as often and they do have to see their vet as often. Thanks so much, if you have any animals with skins allergies, I highly recommend this dog food, you wont be sorry. August 6, 2013
Rated 4 out of 5 by Seems to help! My Maggie has food allergies and this food is one that she will eat and it seems to help somewhat. Have always been exceptionally annoyed that it required a prescription (it is DOG FOOD! I don't even get prescriptions for people food!)but had that issue resolved here so I will definitely reorder.

Rated 4 out of 5 by Balanced formula for sensitive digestion My dog has lymphangiectasia and I had a hard time getting him stable. With the help of his vet and the Purina Pro Plan Veterinary Diet HA hydrolyzed formula, his stool is now solid and he has gained back some of the weight he lost. May 2, 2015
Rated 5 out of 5 by a great product for some, but not, all dogs I remember when my 2 year old Shih Tzu became extremely ill. I rushed her to our vet, and he gently told me that Lily was extremely ill, and that it would take both of us to get her well, but that I should not get my hopes up. He explained about the new type of food that she must start eating. Thankfully I had never fed her any other food except Science Diet - in other words, no table scraps and no human food or treats. It was touch and go for the next week or so - many times I thought that Lily had died, as did my then 8 year old Lhasa Apso Sophie. The 2 dogs had become very close - and I knew that the loss of either of them would be a big blow to the survivor of them. Finally Lily started pulling out - I'm a widow and was living alone at the time. She was fed many times during the day at night - enough to keep her alive but not too much. Had it not been for Purina's Veterinary Diet HS Hypoallergenic Canine Formula, Lily would not be here with us tonight. She's a cute and highly intelligent little dog, and I'm so glad that she is well and is able to stay well. I don't feed her any food at all except the above mentioned food, and Purina, thank you so much. January 26, 2014
Rated 5 out of 5 by Fabulous food for a dog with IBD Our 7 year old Cooper loves this food so much that We can use it as a treat as well. As important - it has been great for his digestive system. April 26, 2015
Rated 5 out of 5 by Perfect Solution We have an 9 year old mix breed that we rescued several years a ago. We discovered he had digestive problems and was not metabolizing proteins well. Until our vet recommended Purina HA, he would have days of vomiting and diarrhea weekly. Purina HA has been the only diet that has kept him stable & well for 8 years. February 25, 2015
Rated 5 out of 5 by The one that works! We've tried a dozen dog foods and this one works. It keeps our Havanese from being itchy. Thank you Purina and Chewy for making the transaction so easy! June 25, 2013
Rated 4 out of 5 by Helped her skin and snoring The HA really helped our Shih Tzu's flakey skin and snoring. At first, we resisted giving her white kibble, but after 4 years, she still likes it and it helps her. Probiotics and Reiki treatments are helping, too. Thanks to Chewy for letting us order directly, instead of through a vet. March 14, 2014
