Moderate calorie content, compared to canine URINARY SO, to help maintain ideal weight.

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

Relative Super Saturation (RSS) methodology predicts the crystallization potential of urine; RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis.

Self Explanatory

I've been feeding my female dog this for a couple of years. She's maintained a healthy bladder. She enjoys the food and eats it right up.

My dogs love it

My dogs have been on it after a urine test showed positive for crystals. After a month, crystal free. So I kept them on it as well as the dry Urinary SO.

Great to hear that your dogs have done well with the Urinary SO

Our Yorkie loves it!

Noah loves his Urinary SO! He’s always anxious to eat the diet he’s been on for 4 years. It’s gentle on his stomach & it helps him maintain a healthy coat.

My dog has been eating this for years but still gets a bladder infection once or twice a year. Also gained weight on it. Very expensive

This is great, it actually works : )

Our Gabby had a pretty rough start in life with thyroid issues and urinary problems in such a young pup. Thankfully we have a terrific Veterinarian who suggested we put her on your Urinary - SO diet. It works fantastic and keeps her healthy. We found if we take her off this diet , she continues to have problems. Therefore, we have and will continue to keep her on this diet. We love our pet and want to keep her healthy. Her coat is beautiful too. Thank you Royal Canine, for loving pets like we do. : )
Royal Canin response
Wonderful to hear that Gabby is doing so well! We love hearing these success stories

Cuddles loves it!

Cuddles, 8 year old Golden Retriever, eats everything in her dish and loves her moist dog food. Her urinary tract problems have been solved. She has been on this product since she had severe problems with lack urine elimination and is now back to her regular self. The Moderate diet was recommended by her veterinarian and has helped her lose some weight as well.
Royal Canin response
Hooray for Cuddles!

Dog loves it and it's improved urine tests!

We have a miniature schnauzer - this is our second. Our first, Holly, suffered from bladder stones and constant UTI's. We had her on another brand of special food up until she had renal failure and we lost her. We adopted another rescue - Lily - miniature schnauzer. Started her on regular food and she came down with a UTI. After discussion with our vet, we decided to change to Royal Canin. She uses this wet food with the dry food combination. The crystals in her urine went down so significantly that they were almost untraceable. This food really saved our furkid's life and made it so much better for her. She loves the taste and eats every bite everytime! The other prescription brand was never as good as this one and we are so grateful for our vet to recommend the switch and to Royal Canin for getting it right and making our pet happy and healthy! Thank you!
