Shit I have an acre and a yorkie. I would love to have a large dog. I\'ve always wanted a mastif I just don\'t want to deal with the poop. Little did I know I could train him to go into a 4 square foot putt putt hole.
What you could do is like hole 18 on a put put course and put in a tube so you can\'t get your ball back.. But instead you can train him to piss in it.
