Canine Urinary SO® Dry Dog Food

Royal Canin Urinary SO is a veterinary-exclusive dry dog food for dogs with urinary health concerns

The benefits

  • Helps dissolve pure struvite stones and helps prevent calcium oxalate stones
  • Lowers the risk of crystal formation using RSS methodology for bladder health
  • Supports urinary health with an exclusive S/O Index, and creates an environment unfavorable to crystal formation in the bladder

Product description

This veterinary-exclusive dry dog food was developed to nutritionally support your adult dog’s urinary tract and bladder health. It increases the amount of urine your dog produces to help dilute excess minerals that can cause crystals and stones. Relative Super Saturation (RSS) methodology is used to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. And this specialized nutrition, with a reduced level of magnesium, helps dissolve pure struvite stones and prevent struvite stones from forming. Lower urinary tract issues may be a recurring concern for some dogs. Talk to your veterinarian about keeping your dog on this urinary dog food for long-term urinary support. And ask them about the right Royal Canin wet dog food and treats to complement your dog’s diet.

Works - but pricey

This dog food seems to be working so far and my dog enjoys it. However the price seems to go up $10 every 3 months which seems far to often and frequent. I'm paying $40 more for the same bag that I started ordering just a little over a year ago. :(

This has kept my dog stone free for 6 years.

Myself and my family are loyal Royal Canin customers. They have a variety of foods that match the different diets of our dogs. Will continue to use them and recommend it.

Dog enjoys it!

My dog has been on the moderate calorie version of this for a while. It’s been helping with his bladder crystals and his accidents in the house have become less frequent (now basically when the weather is bad). It’s also the only food we have had that our dog actually eats without putting up a fuss! It gets a little pricey (we have a 50 lb dog) but it works well!

My dog loves this and doesn't get any UTIs!

My dog has been on this food for almost 7 years. It was recommended by the vet as she had 2 urinary tract infections. After being on it for 4 years, I tried some "natural" dog food, which was cheaper. Of course, she got a UTI. I will never give her anything else. She is 10 now and not as active as she used to be. I alternate between the small dog Urinary SO in the morning and the Moderate Calorie SO at night.

Does it’s job well

We have two ACS on this prescription diet. They hold their bladders longer, and don’t leak as much. They gobble it up, so they must love the taste.
