she is a pet, 6 years old..numerous stool samples run. have tried her on royal canin, natures variety-she won't eat them, very picky. she loved the IAMS-it was off shelf for quite awhile and once it came back these issues popped up. She loves the prescription diet and is fine on it-no more issues but I don't want to feed forever-maybe i'll try the wellness simple solutions. thank you
