About Royal Canin Urinary Health for Dogs

Worried About Your Dog’s Urinary Health?

Your veterinarian is the expert on your dog’s health, so you should always consult with this trusted advisor to find the best urinary health solutions for your pet. Royal Canin works closely with veterinarians to develop dog formulas that support urinary tract and bladder health.

How Can Nutrition Help?

Your veterinarian may recommend a Royal Canin Urinary dog food formula for your best friend. These special formulations can:

Dilute Urine

This helps your dog urinate more often, which can help minimize time for stones to form.

Lower RSS

RSS methodology predicts urine crystallization and is used to develop diets that reduce the risk of stone formation.

Maintain Balance

A precise mineral balance can also help prevent stones from forming.

Set Up Autoship for Consistent Delivery

Last-minute dietary changes can sometimes upset your pet’s stomach. Set your Royal Canin pet food order to Autoship to keep feeding on track and avoid unwanted disruptions.

About Royal Canin

What sets Royal Canin apart is their close collaboration with veterinarians. Through these professional partnerships, they strive to learn everything they can about pet health, including how different formulas perform for different breeds, sizes, lifestyles and therapeutic conditions. Ongoing research and development allows Royal Canin to keep providing the precise nutrition dogs need for a range of medical conditions.

if my dog is on Royal Canine SO what type of treats can she have and still adhere to the diet?
Answer by ChewyDec 20, 2017
Please view the "Royal Canin Veterinary Diet Urinary Canine Dog Treats" on our Chewy site.

Did you change the packaging on royal canin urinary so? It used to be green, but is now brown.
Answer by ChewySep 08, 2019
This recipe has recently undergone a packaging change.

What kind of texture does the regular urinary so canned food have? The reduced calorie says gravy and chunks but the regular canned food doesn't have a description.
Answer by ChewyJun 17, 2021
This recipe has a pate texture.

My royal urinary SO can food has a green label on it and it shows a tan color on the web site, are they the same?

Amazing service

I took my dog to the vet the other day thinking he might have a UTI. Unfortunately he was in surgery several hours later to remove 12 gallstones. He was prescribed a special dog food to (hopefully) prevent future stones. I contacted Chewy to order the prescription food and prescription treats. Chewy contacted my vet and in several days the order was delivered. I am very grateful to Chewy for coming through for us during a very stressful time.

RX food for Picky Pet it a BIG hit!

My sweet labradoodle has developed urinary problems, so we switched to the Royal Canin dry Urinary SO food, which she eats, but reluctantly and only when she's starving (6 months in so not a passing thing!) I ordered the wet food as she has devoured the Gastrointestinal wet by Royal Canin to take Rx pills following surgery. I'm now mixing in @ 1/4 c of the wet SO into her dry SO kibble - she is eating with gusto! A great way to keep cost manageable and keep my queen happy!

Happy Pet

My 7 year old has been put on this special diet and it’s quite expensive s. Was very happy to be able to save a little by ordering on Chewy. Thankfully, she loves this food and I was happy with the delivery.

Had to put one of my dogs on this due to bladder stones. So far, it seems to be helping him.

Works great, but causes gas

My almost 3yr old Standard Poodle has had several UTIs and two instances of struvite crystals in the past 8 months. I don’t feed him dry foods preserved with citric acid as it increases the risk for bloat (he’s an at risk breed, and Royal Canin dry foods are preserved with citric acid). For the first instance of crystals, I fed him the Royal Canin SO kibble. I wasn’t comfortable feeding it long term, so we changed him back to his regular kibble after the crystals dissolved. With this newest instance of crystals, I opted for the canned formula. He hasn’t been back for his re-check, but it causes him to urinate frequently and his symptoms seem to have left so I’m fairly certain that it has worked. My one and only complaint is that it causes a lot of gas– he belches a lot on this formula. The slices in gravy didn’t seem to cause gas, so we’ll probably switch once we run out. He also vomited the first few mornings, but I split his meals into 3 instead of 2 and he hasn’t vomited since.

Good So Far

My sweet fur baby had to start this veterinary diet and I was quite reluctant to change out all of his favorite foods for this new, strict diet. Two weeks into the plan, I am relieved and pleased that so far he has taken to the food quite well. It’s clear that he still misses his yummy treats, but over time, I’m hoping that longing will pass.

Dog is very happy with the taste

Our Jimmy had stone in bladder and had to have surgically removed. Our Vet put him on this food and he really likes it. Suppose to help prevent other stones from forming. Will have first urine test next week, hoping for good results.

Quality food

Unfortunately, my dog who needs this product won’t eat it however, my other dogs do. I like Royal canine prescription products and so do my 5 dogs except the one who needs to be on it.

Very pleased

Our 8 lb 11 year dog had to have surgery for stones. He is a very picky but he likes to the loaf Urinary SO. So we are very relieved that we found something that he enjoyes
