Hill's® Prescription Diet®
u/d® Canine

Bladder Health

Bladder stones are collections of mineral crystals that combine together in the urinary tract. They can cause discomfort and lead to more serious problems that require the care of a veterinarian.

Because the food your dog eats plays an important role in his or her overall health and well-being, Hill's nutritionists and veterinarians have developed clinical nutrition especially formulated to help support your dog's bladder health.

Dogs need the right balance of minerals to maintain good bladder health. Excess minerals can encourage the formation of crystals in the urine, which can lead to the creation of bladder stones.

Rated 4.4 out of 5 by 28 reviewers.
Rated 4 out of 5 by overall great product! Our dog Bently loves the taste and would eat all day if we let him. It's nice to see him healthy once again. Since using this product he has had far less urinary tract infection. I highly recommend this product. It would be helpful if cost was a bit lower or you made more coupons available. Love love the product! September 16, 2015
Rated 5 out of 5 by This product keeps our dog healthy. Thank you for making this product. Our bulldog Sherman will have to be on prescription dog food for the rest of his life but....because of it, he's alive and healthy! Nothing can replace that so thank you! December 1, 2014
Rated 5 out of 5 by Bladder Health Wonderful product! Our dog loves it and has had no more kidney stones since using it! June 4, 2015
Rated 2 out of 5 by My Shi tsue doesn't care for this at this time. I'm at my end of line with trying what ever it takes to get him back to the Happy Dog i had. I know this has to take time for a dog to get use to; but sense his bladder surgery to remove stones. . . .he won't eat and enjoy food like he was.. . He and 2 other Shi tsue's we have don't have these issues. I know i have a unique and challenging problem. . . it isn't easy for a dog any more than a human with food problems. He still needs to eat to stay healthy. The Vet gave me ad to help with stimulating his appetite. . .that doesn't help either. Not giving some kind of treat as they normally got each morning, lets them think I'm being mean to them. . . . I'm looking for something that I can replace treats as an option? Seeking some options with my problem. . Buddy and I , Thank you! September 28, 2014
Rated 1 out of 5 by Poor quality control and lack of customer response My dog's health condition requires he eat the Prescription U/D diet and I have not found a substitute that my Vet will recommend. My dog has been eating this food for the last seven years. Over the past year, the product texture has been inconsistent which has made me question the overall quality of the company standards and the product. One can will be of a dry grainy consistency and the next will be the wet, smooth consistency (the desired and intended texture). My dog doesn't like the dry texture and as a result doesn't get the nutrition he needs. I have called Hill's and received assurances that it is merely a "texture" issue that does not affect the food quality, and can be attributed to severe cold weather separating the water from the food. I was advised to merely add water to the food to achieve the softer, intended, texture. In the short term, I accepted this remedy awaiting warmer weather. However, this problem has now continued throughout the Spring and Summer. If there were an alternative I would pursue it. My complaints surely are not a singular issue and are not being addressed. Hills needs to review it's quality control problems and reestablish it's reputation for quality. For the price paid for Prescription food, there should be more company accountability and customer attention. September 29, 2014
Rated 5 out of 5 by He likes it! Hey, doggie! From the time they were puppies, my dogs, Regan & Taco, would eat anything once. Once being the operative word! I would bring them food, put it in their bowl and they would eat like they hadn't been fed in weeks. But the next day they would sniff it and look up as if to say, "Not this..... again." I literally had 5 different types/brands of food for them, and I couldn't give them the same thing 2 days in a row. My vet suggested Hill's prescription diet wet, so I gave it a shot. They love it! The sound of the can opener longer causes them to bark, instead it makes them run around in circles at my feet. Thanks! October 3, 2013
Rated 4 out of 5 by Great food but still gets stones, however it may be my fault My dog had a bladder cystotomy 2 1/2 years ago and had been on U/D ever since. I will admit I have been giving him non-prescription treats. This past week two more stones were found and removed on Friday. U/D may not be enough. The vet said we may need to add additional potassium citrate supplements in order to keep his Ph at 7. His urine will have a full UA in 14 days when the stitches come out and then again every 3 months for Ph and crystals. an x-ray will be taken every 6 months to be sure no stones are forming. I am hoping that this tie, without the treats, the U/D will be enough. January 26, 2013
Rated 4 out of 5 by Bladder Stones My Bichons love the taste of the food, but don't like they get less as the Kcal is higher than other non-prescription varieties. The benefit is that our older mail bichon has trimmed down from 15.3lbs to around 13.6lbs at age 12+. We are hoping the modified diet will slow the growth of the males bladder stones as we've had one surgery and now 2 basket retrievals in the last 4 years; we just switched since the last procedure about 4 months ago on recommendation from the U of M Vet Clinic....we're hopeful!
