No, I would not feed a prescription food for life. Find the root cause of her problems or try another food (elimination diet). How old is she? Have you tried other foods? I personally have not had good luck feeding Iams or Eukanuba to my dogs long term. I don't know what it is about their food but another food by another manufacturer with the same ingredients will be ok with them.
Are there similar issues with other puppies from her litter? Upset stomach and runny stools are classic signs of a food sensitivity. Have you tried a limited ingredient diet with a protein source that she's never had before? Cut out all snacks except kibble? Don't discount water as a cause, try bottled water.
A second opinion and fresh approach might be in order, some vets just aren't into nutrition or yours could be overlooking something.
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
