Helps dissolve pure struvite stones and helps prevent calcium oxalate stones

Moderate calorie content (11% less calories than Royal Canin Canine Urinary SO dry dog food) for ideal weight maintenance

Lowers the risk of crystal formation using RSS methodology for bladder health

Supports urinary health with an exclusive S/O Index, and creates an environment unfavorable to crystal formation in the bladder

When your dog has urinary issues, easing their discomfort requires special care. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This veterinary-exclusive dry dog food was developed to nutritionally support your adult dog’s urinary tract and bladder health. It increases the amount of urine your dog produces to help dilute excess minerals that can cause crystals and stones. Moderate calorie content (11% less than Royal Canin Urinary SO dry dog food) helps them maintain a healthy weight. Relative Super Saturation (RSS) methodology is used to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. Lower urinary tract issues may be a recurring concern for some dogs. Talk to your veterinarian about keeping your dog on this urinary dog food for long-term urinary support. And ask them about the right Royal Canin wet dog food and treats to complement your dog’s diet.

This product does exactly what it says for my pet!

I have been using this for several years now. Molly loved it the first time I gave it to her and still does.

Formula Change

After only being on the new formula for 1.5 months by Bichon Frise (9yrs) now has tear staining (never been an issue), a yellow muzzle (typically only an issue with food with dye in it), skin allergy issues and intermittent diarrhea. Giving it another week but probably going to start looking for a new food. The old formula never gave her these issues.

Formula change. Holy stink!!

Most recent bag, with new image appears to have a formula change. Springer has been on this food for 2 years. Really helped with preventing crystals, but new formula is producing excessive gas that was not a problem with the old formula. PLEASE SWITCH BACK!!! Tilley can clear a room!

Formula Changed

Like others who commented, my small breed dog was on the green label for 6 years with no issues. I purchased two bags of the brown label and ever since she has gas, loose stools, and gland issues.

She's better!

Our dog, Roxy, was leaving very concentrated urine spots all over the house. I thought she may have a bladder infection but our vet found her urine was loaded with crystals. I can just imagine how painful it was for her to void with the sharp crystals hitting her bladder and urethral walls. He said we caught it before the crystals had time to form into a stone. He had us change her food to Royal Canin Urinary SO dry dog food.and add some water to it. She was better in days, without side effects, and has not had anymore crystals for 2 years. It is expensive but worth it. I save some money by using the Royal Canin autoship program.

Product change

My miniature schnauzer had eaten the green label kibble for years with no problem. Change the formula and he has thrown up more than he’s digested. Schnauzers can’t tolerate the additional fat you’ve added per the response I received from your customer service.

Bloated, constipated and wind

Our female Shichon (6 years old) was diagnosed with bladder crystals. Since going on to this food she is constipated, bloated, having very bad wind and is clearly in discomfort. Back to the vets for their next suggestion.... We have used Satiety and Weight Loss to keep her at a healthy weight and these have been ok but this Urinary SO dry food is making her really not herself at all. We tried the wet version - made her violently sick!

New Formula - sick dog

My dog has been on the new formula for about 7 days and it has made her sick. Up all night with stomach pains and excessive gas. Previously used the green label can for 4 years without issue. I am so disappointed.

So far so good

We were feeding our boy the satiety dry s/o formula for approximately 8 months when we noticed that he was having difficulty emptying his bladder and having accidents in the house. Tests showed that he had bladder crystals which, according to our vet, the satiety formula can cause this to happen especially if your pet has had crystals in the past. After just ordering a brand new bag of satiety, I had to get him on the urinary s/o moderate immediately, no time for transition. I expected that he would have digestive issues with the abrupt change, but all went well. A month later his urine had no crystals and the ph was perfect. He will be on this for the rest of his life, he will be 11 this year. I haven't had the need to order more since the formula change and am hoping that we still get the same results with it.
