Is there any medication available to dissolve kidney stones?

My 5 lb. 11 year yorkie has suffered from stones all her life. Ultasounds showed that her kidneys contain many stones. The last stone she passed was a urate stone. However, I believe she may have had struvite stones in the past, but not sure.
Asked by: Anonymous
Allopurinol is used in the treatment of urate stones. Struvite stones are dissolved by making the urine acidic. Methio-Form is a urinary acidifier available by prescription. There are diets available to treat struvite stones as well.
