We feed our 9 month old Eukanuba Large breed puppy food. In the morning, we give her 2 cups mixed with half a can of Iams wet food. In the evening, we give her a cup and a half of the food in a buster ball. She almost always finishes what we offer her these days. We supplement her diet with Iams biscuits for treats. Best of luck....a stubborn eater is no fun! Kris
