I had to work this past weekend and since the office was (mostly) deserted I brought Chopper along with me. At home Chopper is content to lay down, have a bone, take a nap. But at the office he wanted to hunt - he tracked down every stray crumb anyone had left behind or stash of snacks. After two days he had found everything and he was bored. So he sat and stared at me until I stopped working and took him home.
