My akc Shepard died a few months back. She was a handful(health side), but was trained, and had no bad habbits... Sister gave me a yugo Shepard. He's as healthy as an ox, but a bit more of a troublemaker.
Either way. You can't go wrong.
As above. I trained mine not to jump, but he has no problem opening the gate, then opening the door, or vise versa. I need to teach him to close the door after.
