Smokey is a Black Lab/mix. He loves hanging out in my work shop. He has the best attitude of any dog I’ve ever had. He welcomes all visitors with a healthy bark or two, but has never shown any aggressive traits towards anyone. I’ve had several of my labs on job-sites through the years and have never had any problems with focus or safety because of them being there, although I did have a home owner offer me $500 for my dog the second time they saw her!! My dogs would find an empty, quiet room and lay down till they heard my air hose releasing pressure at the end of the day. They then knew it was time to wrap it up and go home! They are wonderful companions on or off the job!!
