Provides nutrition that aids in the management of pure struvite uroliths.

Moderate calorie content, 11% less than Canine URINARY SO dry, to help maintain ideal weight.

Increasing the urine volume reduces the saturation of urine with calcium oxalate and struvite crystals.

Relative Supersaturation (RSS) methodology predicts the crystallization potential of urine. RSS is used to develop diets that lower the concentration of ions contributing to struvite and calciumoxalate urolithiasis.

URINARY SO MODERATE CALORIE has been specially formulated to assist in the management of lower urinary tract disease in dogs requiring a moderate fat content, or who are more susceptible to weight gain.

Frenchy Favorite

Lola the frenchy has issues with calcium oxalate stones and this food has proven to be extremely beneficial to her well being. She has had 2 surgeries for stone removal and since being on this food we have been able to manage her condition. She also loves the Urinary SO treats and loaf. Keep up the good work Royal Canin. We would be lost without this product.

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!

Change in formula!!

Okay...So my miniature schnauzer who is 11 years old has been on this food FOR YEARS without any issues (4 years to be exact). She has never pooped inside and her stool has been nearly perfect. As soon as the gold label rolled out I've come home to vomit, diarrhea, and an overall depressed dog! This is very upsetting because she is in her golden years and should'nt have to be dealing with projectile diarrhea!! I finally threw in the towel tonight and am transitioning her to a different food. NEVER again will I buy a Royal Canin product and intend to return the rest of the dog food I have at my house!
