As you can see by using the search engine (bladder stones) and checking the various posts and threads at this site. The most important thing you can do is increase water intake, add water to all meals, 3 or 4 small meals per day instead of 1 or 2.
Offer frequent bathroom breaks, opportunities to urinate, observe for normal flow/amount/stream. Keep the bladder flushed to avoid stagnant conditions conductive to stone formation.
Otherwise I would defer to your vet regarding diet and supplement choices, at least till the dog has been stable for a while….then discuss changes with the vet.
Some types of bladder stones tend to recur, there is a genetic component to consider.
PS: Wysong has a prescription food, ask your vet if it would be appropriate….if you like the ingredients better http://www.wysong.net/veterinarian/
