Well, if it was me, I would stay with the RC prescription/therapeutic diet for at least 6 months to a year. Then, if the dog has no reoccurrences (urinary tract infections)
I would try another dog food to my liking.
Again, increased water intake and increased bathroom breaks, opportunities to urinate are the best thing you can do for this condition that tends to be genetic.
Did the dog have an ultrasound? Where other types of stones ruled out?
I say this because there are specific dietary restrictions depending upon the type of stones the dog is making. Discuss with your vet at the next visit.
Best of luck.
