I work at home in my office most of the time. My dog Blue is my constant companion. He comes and goes around the house, but his favorite spot to return to is at my feet under my desk. Sometimes I lose track of him, and think that he is not there... and then I move my feet to find out quite the opposite. He sometimes has a way of slipping in without drawing my attention.
He is my traveling friend too, and he goes with me on a lot of real estate appointments for home showings, etc. My wife and I rescued him from a shelter in June of 2013, and I cannot imagine life without him now.
