I forgot:

Bo was one of those who could not go if he knew you could see him.

He would go deep into the brush, assume the position and look our way to see if we were looking. If we could see him and he knew it, he would stop and go deeper in.

If we were out in a field with nothing to hide behind, he would walk quite a ways before giving in. If we turned our backs he was fine, but as soon as we turned to look at him, he would stop mid-business, and move.

He was soooo unique. The best one yet.
