My Parsons Russell Terrier was suffering from tiny bladder stones about 10 years ago, had bladder stone surgery multiple times and hydropullions to remove the stones from his urethra. He was part of a study at UC Davis and after testing his stones and bloodwork they determined he was had a combination urate/struvite Crystal’s, with this information I decided to put him on Prescription diet W/D which is low protein, low fat, high fiber, I add a cup of water to it to keep things flowing. Has been 10 years and not one issue. I’ve told several people people whose dogs were having the same issue, no more issues to speak of. Hope this help anyone who chooses to use. May save them $. Take care
