My st. poodle puppy is 7 mos old and weighs about 57 lbs. He is not as active now that it has gotten cold outside, but I have still been feeding him 3 1/2 cups a day. He is starting to look a little chunky, but I have no idea how much food he truly NEEDS. He will eat all of his food, and then I have to fight him to keep him out of my other two dogs food. We feed Canidae ALS Original. How much should I feed him based on activity?
