Thank you for your question! Feeding Kidney may support the kidney and bladder, but is not known to dissolve stones on its own. That being said, freeze dried kidney is part of a well-rounded regimen of alternative treatments for pets suffering from kidney and bladder issues. This regimen includes Eastern Food Therapy (food, treats, and supplements) and Eastern Herbals. A complement to the food therapy program is an herbal formula called Crystal Stone Formula, which supports the dissolution of stones by clearing Heat and Damp, resolving crystals, and supporting the bladder's normal healing process. Crystal Stone Formula requires a veterinary authorization, which you can request here: https://tcvmpet.com/pages/get-an-authorization. The food therapy products do not require authorization, just the Eastern Herbals.
