Thank you for viewing. My dog (a Jack Russell, 8 years old) developed bladder stones, and the vet prescribed Urinary S/O. He ate the sample I received at the vet's office without any problem, so I bought a large bag with confidence. However, he gradually stopped eating it, and now he refuses to eat it at all. The vet recommended a different food, so I am selling the unopened 3kg bag. ・Urinary S/O for small dogs, 3kg (unopened) Expiration date: March 2, 2027 Purchase price was 8380 yen.
