Who Should Buy This
This dog food is perfect for adult dogs that have urinary health problems. If your dog has been diagnosed with bladder stones or other urinary issues, this food can help support their recovery. It is also good for dogs that need special nutrition to keep their urinary tract healthy. If you want a diet recommended by veterinarians, this is a great choice.
However, this food is not for healthy dogs without urinary problems. If your dog does not have any urinary issues, it is better to choose a regular dog food. Also, puppies and senior dogs may need different nutrition, so ask your vet before feeding this to them. Avoid this food if your dog has other health problems that need special diets.

Our Testing Experience
First Impressions
When I first got the Royal Canin Veterinary Diet Canine Urinary SO, I was a bit worried if my dog would like it since he usually turns his nose up at new food. I opened the 6.6 lb bag and noticed the kibble had a mild, pleasant smellānot too strong or off-putting. I mixed a small amount with his regular food to see how heād react. To my surprise, he ate it eagerly right away. It gave me hope that this special diet food wouldnāt be a struggle to feed him.
Daily Use
Feeding Royal Canin Urinary SO became part of our daily routine quickly. I noticed that my dog seemed satisfied after meals and didnāt beg for extra snacks like before. The kibble size was just right for him to chew comfortably. I also appreciated how easy it was to portion out the food according to the feeding guidelines. Over the first few days, I watched closely for any changes in his bathroom habits since this food is designed to support urinary health.

After discussing with my vet, I understood that the RSS methodology Royal Canin uses really targets the root of bladder health issues.
