I teach lessons out of my home.  Which is great, except that Chewie is excessively social and has to be right.in.the.middle of whatever's happening.  When I teach, I put him in his playpen in the same room as me.  He's happy, because he's with me, and I'm happy, because he's not getting in the middle of what I'm trying to do.  Usually he just lays down and goes to sleep, but he has a few toys and a water dish and a little room to move around.  Of course, things always go better when I'm able to walk him every day, but we're dealing with cold weather too.     
Maybe you can try putting a playpen/enclosure in the same room where you're working?  That way, he's with you, but you're not worrying that he's into everything.  Also, maybe you can give him a stuffed kong to keep him occupied for a while.
