Bests & Worsts Reviews from Amazon

I saw this on Amazon, Chewey & PetSmart, so thought it would be a real product that had been tested. My daughter, a researcher/ professor in evolutionary biology laughed when I told her why I had stones in the dog’s water. The study they cited from McGill University was a lie, go to the university website.. Apparently it’s scientifically impossible and their explanation makes absolutely no sense to a knowledgeable scientist..
