I have a two year old pitbull who is very active and is 70 lbs. He isn't chubby though and doesn't look fat. I feed him 4 full bowls a day in a regular sized 7 inch bowl. Plus, food and snacks throughout the day. I never had a dog before so I don't know if it is a good idea but he looks nice and trim and muscley. He has very high energy and lots of muscles. Should I cut back???
