Hi Cherie G-
Take a look at the Rx Royal Canin Calm or Adult Small Dog kibble. They both have the S/O index. The s/o index means they are suited for dogs with struvite or oxalate crystals. It would be nice to know which type your dog has.
Hill’s Science Diet also has Rx food for pets with urinary tract issues.
I feed my cat the Feline RC Calm prescription kibble with some OTC canned food for moisture.
If any of these options look appealing, have a talk with your vet to see if you can get a prescription for one of them. Hope this helps!
