What makes a dog person?

Another memory Jog....after some thought....this makes some sense....

Talking about our dogs perceptiveness, or ability to read people/other animals. Back in my bay pen (competition) days....I had a pretty dang good dog. He NEVER caught out but would get super tight on set up hogs (nose to nose) and tight on rougher hogs but not AS tight (2-3 feet). I would always have this dog facing the chute when the hog was released and This dog...I think could read these hogs right outa the chute and know how tight he could get without getting nailed right off the bat.
