Hi, Lin, My female dog has a congenital stone problem that killed the father and sister. I keep her clear by giving herbs daily. They are: Uva Ursi - this is powerful, can not be used for long period of time, and may hurt the stomach so I get around that by giving two pills for two days a week, with one pepcid each time. The rest of the week, I gave Echinacea - two pills once a day. Have done this for three years and she has been absolutely clear. My holistic vet says to keep it up. I recently switched the Echinacea to Parsley to give her system a change - it's only been a couple of weeks but every thing is fine. Doing an internet search you will find other herbs that are good for kidney stones. I like the brand Natures Way and GAIA.
Another thing to consider is learning more about magnesium, here's a wonderful article from Mercola. com. http://www.mercola.com/2004/aug/7/miracle_magnesium.htm Hope you find what works. Take care, Cindy
