Description

Lower urinary tract disease (LUTD) refers to a group of disorders that commonly leads to irritation of the urinary tract and corresponding undesirable clinical signs.

What causes Lower Urinary Tract Disease? In dogs, bacterial infections of the urinary tract and the presence of stones (uroliths) in the urinary tract are the most common causes. This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.

Key Benefits

  • Canine Urinary SO is a complete and balanced diet for adult dogs formulated to aid in the nutritional management of calcium oxalate and struvite urolithiasis.
  • Reduced magnesium level supports urinary health
  • Royal Canin Urinary SO Index® promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate 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
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals

Note: Royal Canin Veterinary Diets require a veterinary prescription. This product will not be shipped until a copy of a valid prescription authorization is faxed to 1-800-619-7973 or e-mailed to rx@chewy.com.

Feeding Instructions

Transition Instructions

We recommend at least a 7-day transition before you begin feeding the new food exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet’s digestive system to smoothly adapt to the new food.

Frequently Asked Questions

How are Royal Canin diets preserved?

All of our dry diets are preserved naturally with mixed tocopherols, citric acid, and rosemary extract. Our canned diets are naturally preserved and sterilized during the cooking and canning process.

Where do the ingredients in Royal Canin diets come from?

We select our ingredients based on multiple factors, including the supplier’s compliance with our quality and food safety requirements, consistent availability, and on the nutrients required to meet the dietary needs of the pet.

Royal Canin is making strides towards sustainability by attempting to obtain sources of raw materials as close to each manufacturing facility as possible. In some cases, we use international suppliers, because only those suppliers can offer raw materials that comply with our quality and food safety standards.

Why do some Royal Canin diets contain by-products?

Royal Canin chooses ingredients because they deliver high-quality nutrients that support our customized pet food formulas. Using chicken by-product meal instead of chicken meal for example will allow Royal Canin to maintain its highly customized nutrient standards while achieving a more secure and sustainable supply.

Why do some Royal Canin diets contain grains?

Grains can be a healthy part of any cat or dog’s diet. As always, we focus on the nutrients each ingredient provides and grains can provide many important nutrients.

How do you ensure Royal Canin diets are safe for my pet?

Our Quality and Food Safety systems are state-of-the-art and we continue to invest heavily in new technology to make sure they remain that way.

  • We put our suppliers through a rigorous selection process that doesn’t end with our first purchase.
  • We monitor every load delivered to our plants to verify the safety and quality of the ingredients we use to make pet food.
  • We perform tests on finished pet foods before they are shipped to our customers.
  • We manufacture every pet food we sell, in plants that we own; our plants are ISO 9001:2008 certified for Quality Management and ISO 22000 certified for Food Safety.

How do I know which Royal Canin diet is right for my pet?

Based on size, age, lifestyle, and breed, each cat or dog has unique nutritional needs. For healthy pets, use our Product Selector to find the right diet for your cat or dog.

If your pet is experiencing health issues, please refer to your veterinarian for more information. Your veterinarian will consider multiple factors when recommending an appropriate diet.

  • Amazing Dog Food

    My dog had a pretty extensive and expensive surgery to remove some bladder stones. The doctor recommended Royal Canin Urinary Dog Food, to help keep the number of minerals down and overall, help his urinary health. I tried 2 other pet stores, finding that it was quite expensive! I remember seeing a commercial for Chewy and thought "Why not try that?" I will never go back! Chewy has great prices and offers auto-ship, which comes in handy with my busy life! Some may look at it and say "Ooh, XYZ amount of money?" I'd take $45 of dog food over a $700 surgery anytime! My dog is SO picky so I was afraid he wouldn't like the food. I was wrong!

  • Special Diet For Maggie Mae

    By on

    Our dog developed three bladder stones that she had surgically removed. The vet then put her on Royal Canin Urinary SO Dry Dog Food. Dealing with Chewy to get the prescription emailed over and the ordered shipped out was flawless as usual. I love working with the folks at Chewy. We have worked with them for years and always recommend them to everyone we know. We even recommend them to people we don't know. We will tell people in the waiting room at the vet's office about them.

  • Miracle Food

    By on

    I have a Pomeranian who has had struvite and calcium phosphate stones. She had already had surgery once to remove them, but they returned. She refused to eat other urinary care foods, but since she has been on Royal Canin SO, her urinary numbers are perfect and the stone she had has dissolved. She is finally a healthy and very happy little girl. Royal Canin SO is a miracle food for her and I am overjoyed!!!!

  • A diet that works for our dog

    By on

    Our younger dog, a Schnoodle, had bladder stones at the age of 1 1/2, and had surgery. After that, our vet put her on the Royal Canin prescription food. I was worried at first that it didn't have enough protein, but that's easily supplemented by a little cooked chicken. I must stress that this is the only type of dry food that she gets.....we even use it as her treats.The more important point is that she's almost 5 now and has never had any further urinary problems!

  • Dog loves the food.

    By on

    Our 2 year old dog Roxy can't wait to get this dog food. Her head doesn't come up from the bowl until the last piece is gone. This is the food she will need to stay on the rest of her life so wish there were some chose of flavors, beef,chicken etc, to give our dog some variety. Also would be nice if larger treats were offered maybe the size of store bought dog biscuits for giant size dogs.

  • Save money by buying from Chewy.com!

    By on

    We used to buy this food from our vet, for 60 dollars per 17 pound bag. It was prescribed to our 2 year old, 20 pound chihuahua/pug mix, after we found out that she had crystals in her pee, & kidney stones developing as a result-- they said its probably genetic, because she's so young and otherwise very healthy. Since starting on it several months ago, she's been perfectly healthy and hasn't gained any extra weight from this dog food (despite it being higher in calories) :) She LOVES the taste of it (surprisingly) and my sister's pug/beagle mix loves it too-- so much that we have to make sure to feed them in separate rooms when we visit, lol.

We bought the 25 pound bag from Chewy.com, for the SAME price as the 17 pound bag, at our vet's office! So we saved a TON of money. We essentially got 8 extra pounds of dog food for the same price (with very fast free shipping)! Chewy.com has amazing prices and great customer service. Highly recommend-- especially to other pet parents who have to buy prescription or specialty foods for their fur babies :) We will only be buying from Chewy.com in the future! … more

  • Even great for picky eaters

    By on

    I have 2 year old Siberian husky, AKA the worlds pickiest eater. I have struggled with her for months to try and find a food she liked; however, after taking her to the vet for a UTI, he informed me that she had crystals in her urine and would need to be put on a special diet. After he recommended this food, I immediately checked Chewy, because I knew it would be cheaper. Of course the food had to be approved from my vet, which Chewy took care of for me the same day I ordered it. I was afraid it would take forever to get the food, but it was on my doorstep in 2 days. At first my dog, luna, wanted nothing to do with the food and would just turn her nose up to it, but after a few days she finally I have 2 year old Siberian husky, AKA the worlds pickiest eater.

More and more each day she started giving the food more of a chance, and I found that wetting the food with hot water definitely helps her eat it. I also reward her with a small bit of raw food after she eats this food and now that she knows she gets rewarded, she eats her food in seconds! If you're on the fence because your dog is picky, try some of the things i mentioned because it's worked wonders for me! … more

  • Super Customer Service

    By on

    I mistakenly ordered prescription cat food instead of dog food. The customer service rep was super! She understood the mistake, refunded the cost of the cat food, and sent out the dog food within two days. Per her request, I donated the cat food to the local animal shelter and they were thrilled to receive it. My dog loves the food, and a helpful customer service rep with a sense of humor made all the difference in this interaction! -:)

  • Food change for my miniature schnauzer

    By on

    Recently, my 9-year-old mini schnauzer had to have bladder stone surgery to remove bladder stones. Always before, we have had trouble changing Shadow's diet. This time, there have been absolutely no issues, and he loves this food. He used to turn up his nose at his old dog food and would only eat it when he was very hungry. His old dog food was prescribed for the excessive tartar on his teeth. His new food is supposed to be great at preventing more bladder stones from forming. The only downside is that I now have to brush Shadow's teeth every day, but he is very patient and enjoys the doggie toothpaste!
