Wendy – Sorry your pup isn’t responding to the Hills Science Diet. We had similar results early on with our Miniature Schnauzer but it was more related to the fact that she just didn’t like/wouldn’t eat the prescription Hills. After 3 surgeries to remove bladder stones, she’s been having great results with prescription Royal Canin Urinary SO (dry, wet and treats) and Purina Pro Plan Veterinary Diet UR Urinary Ox/St Canned. We were fortunate to get samples from out Vet before having to commit to a full order from Chewy.com where the smallest order size is 12 or 24 cans at a time. Also, I did see the Royal Canin prescription dry food in Petco the other day. You can read other comments I have made above. Good luck, we know how hard it is to treat this condition which is more common in some breeds than others.
