Q. Is there a over the counter med we can buy to help break up the stones
A. Not likely. Stones can be broken up through diet and/or medication but it depends on the stone's makeup. A urinalysis may give your vet an idea of how to treat. If they can't be broken up, surgical removal will be required to prevent obstruction, chronic inflammation or chronic UTI.

A. There is no over the counter medication for stones, neither there is prescription medications. most stones cannot be "broken" medically, some stones (a minority) can be dissolved with a special prescription food.
Bottom line, if the stones are big or many - surgical removal is pretty much the only option.
