Clicking?

Today he has been hanging out at home with me. He will sometimes sit in my office with me. The cushion from my dish chair works as a dog bed (since he wont get in the chair!) so he has been sleeping comfortably there- especially during breakfast and lunch!
We worked on some clicker training. He knows sit but does not lie down for me so I figure I will start there. Plus it is a good way to "bond". He seemed a little distrustful when I started so we have backed up to "sit" until he gets used to how this clicker training works! He seems very smart and has a great attention span so I just need to let him get used to it all.
