Pixel knows "go to your room." When I tell him that when I leave for work, he goes right in and sits on his bed awaiting his treat lol Though he isn't in just a crate. He is in an exercise pen ATTACHED to his open crate. I taught him that "trick" in just 3 days. I would throw a treat in every morning and then when he ran in to get it I would say "good go to your room." Now when you say "go to your room" he just goes
Good luck!
