Looking down on him he does have a waist. He is currently on science diet puppy due to another dog we had here for my brother, decided it would be easier to keep them on the same food until he went home. He gets 6 cups a day, which is the recommended on the bag. We take him for at least a 30-45 min walk everyday, a lot of times he has 2 walks a day, plays fetch and comes with us to the park with the kids. So he is active. Maybe we need to switch to a lower calorie food now that the other dog went back home?
