If this dog was outside and able to watch for five minutes longer, he could be the forema- the foredog at the next job site.
He quietly sat outside and watched every worker's actions, on the ground and the climber in the tree. He wasn't on guard, it looked like he was learning. As ropes would swing around, he looked where they were going. When branches came down, he moved to see where they going to be put. Eventually, his owner called him to come back in and without hesitation he trotted right back inside and the job outside continued.
