Rated 4 out of 5 by from My dog suffered from bladder stones. Thank God and your food that she has not had an incident since her major surgery 3 years ago! We also feed the canned version. I must say that she still eats both of these specialized foods readily without any added treats to make them more palatable! That's a plus with any food out of the norm. Thank u snd keep up the good work!

Rated 4 out of 5 by from wonderful multiple features I bought this product about a year ago using Royal Canin canine SO food for a couple of years. My dog had developed allergies and this product is a wonderful alternative for a dog with multiple medical problems. She had urinary and allergy problems that you have combined a food to help with both. She likes the food and the palatability is great. Great job.

Rated 5 out of 5 by from Health saver My little girl had so many issues before I changed her diet to Royal Canin. After her surgery for bladder stones, our vet suggested the Urinaty Blend. This was 2 years ago and Things have been awesome. She is a happy little dad hind once again. I have no pictures because my little Hoku is pure black and very camera shy. I've tried so many times to no avail.

Rated 5 out of 5 by from I recommend this food I am on my third bad of the HP/SO combo food. I have one dog with urinary issues and one with allergies. It's so nice to be able to buy one bag of food for both dogs. Also my dog with urinary issues is a very picky dog and she now can't wait to eat and that makes us happy as well. This food is a dream come true! Thanks Royal canin

Rated 3 out of 5 by from Makes my dog extremely thirsty My vet recommended this to prevent recurrence of bladder stones and diarrhea in my miniature schnauzer. He likes the food but it makes him extremely thirsty. I am mot sure if this is what it is supposed to do, but he was not this thirsty on the SO diet.
