We feed Nutri Source puppy food, and have had great luck with this food. It is the one with grain, in the purple bag and says "small/medium breed puppy". It is a very high quality food. We recommend feeding 1 cup of food a day, 1/2 cup morning and 1/2 cup evening. We also recommend keeping your puppy on puppy food until a year of age. Here is a link to Nutri Source puppy food.
