Thanks, everyone! The woman told us that she had been taking Bo to work with her. She is a therapist and most of her clients were happy to have a big, friendly dog around. One guy had to complain about him, though, and so she decided to stop taking him to the office. He has managed to get out twice since she stopped taking him. When we found him, he seemed very happy that people were paying attention to him. After the lady came and got him, she said that the crabby, dog disliking client can go find another therapist because she is going to start taking Bo to the office again.
