We recently starting feeding our 5 year old Shih Tzu your dog food after literally 5 years of trial and mostly error. We tried every dog food out there and nothing worked for him. He is now doing amazingly well after less than 2 months. He just devours it and has lost about 3 pounds. No vomit, no drippy eyes, no diarrhea! We have him on the Turkey and Veggie formula.
