I'm not sure what is going on with Buster, but he's been sleeping in the living room for the past few weeks (previously he slept in our bedroom) and he hasn't been hanging out with me in the home office on the days I telecommute. Perhaps we can chalk this up to his "teenage" dog years--time to rebel against the parents. Prior to this, he was at our side 24x7. This was due in part to the fact that he's still considered a puppy (and we didn't want him destroying everything in the house) and in part to his separation anxiety issues. But, now, he's practically independent!
Not only that, but he is down to about 10 minutes of "idiot" time per night (down from about 2 hours). Of course, we make sure he gets plenty of exercise. In fact, I recently bought this nifty contraption just for him:
We've only used it a few times, but it tires him out nicely. Far better than the two mile runs Brian normally takes him on, and in less time as well.
