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.

Rated 4.8 out of 5 by 80 reviewers.
Rated 5 out of 5 by Worked perfectly, just as vet said it would. Our dog liked the food and I was able to put her antibiotic in the soft food without her noticing. It worked perfectly. January 9, 2017
Rated 5 out of 5 by Dog loves this food! I had to get my dog on this food quickly due to her health issues. customer service was GREAT in getting this order out and I had it in a couple of days. Hollie is a toy fox terrier and the kibble is very small which works well for her. She likes it so well I have to give it to her a little at a time so she doesn't gobble it up. I also ordered the dog treats that go with this food and she loves them as well. Time will tell but so far I am very happy with this product. December 10, 2016
Rated 5 out of 5 by Oustanding Customer service I ordered the SD for our small dog, I didn't realize the food comes in different sizes as well as the bag. The customer service representative went above and beyond to explain and ensure I got the right size for my dog. Outstanding service on a job well done! November 29, 2016
Rated 5 out of 5 by GREAT food!! My dog goes NUTS for this food! It is a prescription and you'd think that it would be nasty but even the smell seems appetizing to him!! Same thing with the treats!! We were a BLUE family but I think this is much better for him.!! November 27, 2016
Rated 5 out of 5 by Prescription Royal Canin My veterinarian put my 2 Bichon Frise dogs on the SO Urinary Track food. Good choice. Small Kibble. One dog had 7 bladder stoned removed about 6 years ago. He has done well on this food. It was an excruciating painful recovery for him, and I wouldn't want either dog to go through surgery... Service from was wonderful, and I will plan on receiving their food every month. Barbara, Pepe & Bella November 18, 2016
Rated 5 out of 5 by Dog loves this food!!! Eats more than she ever did! My Shih tzu loves this dry kibble food. She never ate her food everyday. It would sit till she was ready to eat it. She was put on this food after she had bladder stones removed. I divide this food in half so she can eat twice a day. She always wants more. Plus it tends to make her drink more which is a good thing. Hopefully she will never have stones again. * I make treats from the can food. Freeze tiny little balls. Loves them. November 15, 2016
Rated 5 out of 5 by does what it's supposed to After a bladder surgery for a very large stone blocking her from urinating, my Miniature Dachshund had a 3 month checkup, and there was no sign of any new formation. Yay!! November 21, 2016
Rated 5 out of 5 by Great dog food for dogs with stone problems Our Maltese shih tzu had 3 large stones that were going to require surgery. The vet recommended this dog food and we made the switch fully and within a month it cleared up the stones and no surgery was needed. If you have small bread dog's this is highly recommended.
