This is our newest trick. I'm still working on building up distance so that I can eventually send him completely from across the room to go shut a door. Next thing I need to is train the same thing with multiple doors in the house. and here's the same trick from a little bit further back... Here's how I taught the trick: I started off with having Bamm target my hand with his nose. When he got the hang of that I had him target a post it note in my hand. I then taped the post it note to the door and clicked for any targeting to the post it note on the door. After many repetitions I started only clicking for targeting with the door actually being pushed. We worked our way up to building more and more of a push until he could close the door completely. Then I added my verbal cue. Now we're just working on building the distance.
