whenever Miko has tummy troubles, we give her nothing but rice made with chicken broth. once she seems to be feeling better, we mix her food with the same rice (actually we do that regularly)
we feed her nutromax adult food (lamb and salmon recipe) and it's very rich. it's great stuff, but since it is so rich, the rice seems to help ease her tummy. she has to eat canned food to eat enough and not lose weight.
best of luck!!!
