As you all know, Tank goes to work everyday with his Dad. I mean of course, why would he not, he is Velcro Dog. On rare occasions, Jack will leave to go somewhere where he can't take Tank with him - a meeting, lunch, etc. When these rare occurrences happen, this is what Jack always sees when he pulls back up to the office.
Look at that face! Susie and Eunice, who work with Jack, tell him that every time he leaves, Tank never moves from this position. Such a sweet boy!
