Sorry to take over the thread a bit, but apparently, with all breeds, this has been happening more and more lately. They seem to think there is a sort of connections between young dogs (2-3) years getting these stones. There is a study going on, I offered the stones and info about Johnny, but never heard back. I know they are not funded though so maybe they can only do so much. I'm thinking it's not just the water, but the food. Most of our food now we are concerned about high end, no grains, blah, blah, blah. But maybe there is something to be said for the cheaper food where the dogs lived and had no issues with stones. I know a couple of dalmations who had stones who were put on a cheap dog food and lived to be 14 or so. You kind of have to wonder if what we think is quality food is really worth it. There are lots of questions that are still unanswered when it comes to the stone formation.
