We also use give a dollop of pumpkin every evening.
Tilly, our beloved Aussie pup had severe intestinal issues - vet (he was a homeopathic practitioner as well) had us give come cottage cheese, pineapple, and pumpkin, and wanted 3 meals a day; worked pretty well to keep things at bay for years. Of course, what one pup gets, the others must also get, so cottage cheese (lunch) and pumpkin (dinner) are always on the menu (we stopped the pineapple because the acidity seemed to upset Maggie's (the Golden one) tummy some.
Keep good care of those pups!!
