I trained all four of mine to go on pee pads inside. Too many hawks outside. I didn't want the hassle of training my male, too frustrating, so he wears a belly band. So much easier and less frustrating. Some males are easy to train, others just don't get it. You'll get a lot of opinions on this, you just have to decide what you want to do. The only advice I can give on training to go outside is constant watch for signs to go, patience, lots of patience, be VERY consistant, and a whole lot of praise when they get it right. No yelling or punishing, they don't really understand it unless caught in the act and then only a firm NO and immediately take them outside.
Good luck!!
