Jackson is 17lbs, very active, and eats 1/2 cup of kibble per day. He also gets wet food mixed in.

But when I used to try to feed him the recommended amount on the bags (1 cup +) he never ate it. I think he would turn into a tub of lard if I fed him more than 3/4 cup lol. I keep him in this condition most of the time:
