From the day I got the chocolate one at five weeks old I was taking him to work every day. Eventually the type of work we were doing changed and I couldn't take him as much. The yellow one has only been to work about a half dozen times. That's part of the problem. I think he has the dog equivalent of anxiety issues, mixed with ADD and OCD. But he is getting a lot better. And it's rare that we're in the car that long with him. I have too many little kids to go on a lot of long road trips.
