Bladder Stones

That is amazing that the stones dissipated in a month! A lucky little dog. The most common urinary stone in a dog is called Struvite with the second runner up being the Calcium Oxalate. It is a very good sign that they can be controlled by diet. Hills makes a diet called C/D for the control of Struvite crystals but it is not labeled for Calcium Oxalate. If your vet feels your dog had Struvite stones, you will need to keep your dog on the prescription food and only that food, for the rest of his life. No treats unless the are approved by the Vet. Give extra attention to the water bowl cleaning and changing twice a day. You may notice your dog will urinate more volume and drink more on the new diet.
