I have a friend who's senior greyhound lab mix is going thru the testing for stomach/intestional ulcers and she has her on boiled rice and hamburger for now. I wondered when the time comes to get her back on kibble what would be the best choice? She will need something easy to digest and easy on her tummy. I know there are a million choices out there but since my dog hasnt had these problems I dont know have any food choice advice for her. Anyone have any ideas?
