To completely dissolve the stones takes 4-16 weeks, depending on the size and number of stones present. Otherwise, the diet will not work properly and your pet will be plagued with this condition longer than necessary. Follow your veterinarian's directions when feeding the prescribed food, whether for treatment or prevention. Although these foods may not look like your typical dog food, most dogs readily eat these diets and find them palatable. Warm the canned diet to, but not above, body temperature.
Hand feed the new diet for the first few days.
Mix the dry diet with a little warm water and wait 10 minutes before serving. Over a 7-10 day period, mix the diet with your pet's former food, gradually increasing the proportions until only the new diet is being fed. Be patient, but firm with your dog. This is important. The success or failure of treatment depends to a large degree on strict adherence to the new diet.
