Leo: a large, adult male Australian Cattle Dog (Blue Heeler) in Waterloo, IA . Aren’t I a handsome man? I am an easy going fellow who was found as a stray in June. I walk like a champ on a leash and appear to be house trained. I like to be active, but am not a high energy dog. I am super smart and can pick up on just about anything you want to teach me. My adoption fee is $100 plus a $50 deposit which will be refunded after I am neutered.
