Great question! Hill's Science diet has a diet called Hill's s/d that helps reduce the risk of struvite stone formation. I would speak to your vet to see if they feel that switching to Hill's s/d would be a good option for Smudge. Keep in mind as well that there are other causes of diarrhea in dogs, such as intestinal worms, GI illness, or eating something rotten so a health check with the vet would be a good idea to rule out a medical cause before considering switching foods. I would have her seen by a vet tomorrow. I hope this helps!
