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

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.

  • Great Service, Great Price, Great Product

    The dog food arrived very quickly... within 2 days. It was well packed in a perfectly sized box with no tears. The bag has a good zip-style re-closeable top that actually works. I have 2 dogs, and only one of them needs this food, but the other dog tries to steal this food -- it must taste delicious to dogs. Chewy had the lowest price I could find for this food, and they got my veterinarian's approval to dispense this prescription dog food very quickly.

    My basset had to change her diet ASAP due to bladder stones/surgery. I called Chewy because I had just received her prior prescription right before I found out about the change. The big Chewy box hadn't even been opened yet. They were so kind and understanding about the situation and getting me a refund for a now unneeded product. The new food was delivered so fast I still had leftovers of the old diet. As far as the Royal Canin SO (both wet and dry), my girl seems to like it better than the Hills and gobbles it up. Fresh, crunchy dry food and undented canned food delivered with speed. Doesn't get much better than that.

    My Standard Poodle Piper is a Rescue, who was born with several birth defects in her urinary tract. She's been to several Vets, to the University of Florida, & internists for corrective surgery. This food helps keep her urinary tract health & free of crystals. It helps reduce the number of UTIs she gets. The customer service team at Chewy reached out to me & our Vet to make sure they had all the paperwork needed for this prescription food. Thanks Chewy!

  • Royal Canin dog food saves us again.

    Our rescue dog Heidi has had some problems. As a pup she wouldn't eat and when she did she would get sick. We put her on a Royal Canin Limited ingredient dog food and she was fine. Now she has a urinary problem which could lead to kidney stones so we turned to Royal Canin again. Their Unrinary SO food has allowed us to manage the condition and Heidi is happy again. Thank you Royal Canin for your wide variety of specialty foods.

    They said what they would do and did what they said. My dog must eat a R X, dog food which is quite expensive when purchesed from any of the big box pet supply stores. I heard from a friend about Chewy, and gave them a try my order was cheaper and the order was 0n time and right to my door.

  • Great food per veterinarian recommendation.

    By on

    This food has so far kept away the bad bacteria that keeps affecting my beloved coco. I pray this food does the trick it appears it has helped a lot of other animals with the dreaded UTI infections. They can’t talk and to know their suffering kills me.

    My Shih Tzu had numerous bladder crystals that were jagged and had to be removed. My vet recommended this food to prevent any further issues. We have had no evidence of them returning since being on this diet. I put my other dog on it too as she is the same breed just in case.

  • My dog loves this food

    By on

    I was concern when Doctor said my dog needed to go on this diet. My dog has always been a picky eater. So after his surgery I mixed this food with his old ones, just to ween him off. And to my surprise my dog went at and wanted seconds. So I can say I am very pleased that he has found something he enjoys. I truly will recommend this Royal Canin Veterinary Diet.

  • My dog loves the taste!

    By on

    I researched several brands of prescription food for my dog when she contracted her second UTI in a few months. I decided to go with Royal Canin. She LOVES the food. It’s too soon to tell if it’s made a real difference with her frequent accidents, but I didn’t expect it to work immediately. I’ll continue to feed it to her if I see results in a few months. The ingredients aren’t very enticing if you’re looking for something preservative-free, but I overlooked that because all of the urinary health foods I researched seem that way as well.

    My dog ended up being put on a special diet . Didn't think I could afford to keep buying the special food until I found you site. A lot cheaper than the Veterinarian office charged and fast delivery. Thank you so much.
