This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. 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. 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.

My GSD/Border mix, Sasha, was put on this food after emergency surgery for struvite bladder stones at almost 4 yrs of age.When she was nearly 14 (in 2020), the formula changed slightly (increase in % fat), & she developed pancreatitis. My vet recommended mixing this food with a lower fat food (Blue Buffalo Healthy Weight) & put her on a liver support supplement. In 3.5 months, her blood work was back to normal. I lost my girl in Dec 2021 at age 15.5, & she ate this food for nearly 12 years of her life. I am back checking the price due to the possibility that one of my new rescues (Old English/? mix) may have to be put on this as well. I can't believe how much the price has increased in less than 2 years. From Dec 2021 until now, it has increased nearly $22 for the 25.3 lb bag. When I first started using this food in 2010, it was barely $50. I can't argue with the results - my Sasha never had an issue with crystals/stones for the rest of her life. However, just like everything else, the price has skyrocketed. Soon, the average person won't be able to afford to feed a pet, especially if that pet has a health issue.
A long history of utis, a couple encounters with crystals but no stones we tried Royal Canin this time and hoped to just remain on it since she won't eat science diet urinary. She cleared the crystals in a month and her oh went up to 6 (she has hx of low pH). Just opened the 2nd bag and after a couple of days she had abnormal panting/heavier breathing and wet the bed 2xs in 1 day (huge wet spots) even after being let out more due to increased thirst and output. She had no clue it was happening in her sleep. This is a 6yo lab that's well house trained. I immediately stopped the food (trying her 6th food to see if we can avoid utis that's not urinary food now). Almost 24hrs and she's slowly feeling better since discontinuing this. panting decreased noticably, she's not laying on her side struggling to get comfortable, and has more interest in her surroundings again so hopeful it didn't cause any permanent issues at least. -nothing like going from one extreme to the next!
I don’t write reviews, but this is worth sharing so it doesn’t happen to you. We started giving our Aussie this food due to crystals in her urine and kept her on it for a bit even after the crystals were gone (per our vet’s recommendation). All of a sudden our dog developed a UTI and started peeing herself in her sleep - she has never had issues with either previously - a very healthy senior dog. When the UTI was gone, she was still incontinent and come to find out it’s because of the Urinary SO food. Beware of feeding this to your dog long term.
Trying to transition my dogs from Hill's Science Diet Urinary + Metabolic to Royal Canin Urinary SO. Both dogs did fine and like Royal Canin but have had trouble with regularity since changing. After 4 days of no go, it's time to see the Vet. Did NOT expect this. Cha-ching! Maybe the Metabolic contained something that stimulated their digestion? If so, even the Vet is unaware. So frustrating!!!
Our little Sassy didn’t care for the Royal Canin urinary. The 3 stars is for the food, Chewy gets 5 plus as always wonderful company.
Our dog had a health issue and limited diet. Our dog was very happy with this food, dry & wet SO diet.
This food is great except this one order the bottom of the food in the bag had gotten damp somehow and I had to throw it away.
My dog enjoyed this food, and it did its job of dissolving struvite crystals. However, I didn’t feel comfortable feeding this food long term as it is preserved with citric acid. When used as a preservative in dry food, citric acid increases the risk for GDV/bloat (Purdue University study). My dog is a Standard Poodle, so he’s already an at risk breed. We fed this food when we had to, but took him off of it after a month. He’s also battled frequent UTIs in addition to 2 instances of struvite crystals, so we are back on Royal Canin SO to see if it helps. The only difference is this time I’m feeding him the canned formula. Both the dry and canned formulas appear to work equally well, but the canned formulas also have the added bonus of providing him with more liquid in his diet which I’m sure helps a little more.
Our vet recommended this for our puppy for a small health issue. problem is that this dog food actually requires a vets prescription to get and as you can imagine a price to match that. None of our local stores carry this, but this is where Chewy shines. They talk to the vet so we don't have to and auto delivery helps us manage when a new bag arrives, plus we get a small discount with auto delivery. We have two dogs and they are transitioning from their old dog food to this and so far seem to like it.
Tried this brand out for both of dogs to help aide / prevent medical issues and I’m never going back to any other brand - regardless of the dog! Unless I have to of course. Royal Canin not only helps my pug with his urinary issues but it also stopped his shedding and weight gain! We add a little broth to it to soften the food and he scours it up every time. Love everything about it - highly recommended to everyone!
