Hi Lisa P-
Sorry to hear about your pup’s bladder stones. I have a cat with urinary tract issues also. It can be scary stuff. After his blockage, I researched the prescription foods a bit and was led to believe that the only Rx food that cannot be fed long term is the Hill’s s/d food. It’s meant to be fed short term to dissolve the stones and then be followed up by the Hill’s c/d food for long term. I think is safe to feed all the other urinary Rx foods long term, but you may want to work with a vet on whether it’s safe to supplement with some fresh foods or recipes for some safe homemade meals.
I chose to feed my cat mostly the Rx canned food with added water to keep his urine as diluted as possible. Also making other changes to ease his anxiety. It seems that urinary crystals and stones are common in stressed out male cats. In dogs, it seems that they are more commonly associated with urinary tract infections. Which type of stones does your dog get?
