Here's our goober. We named him Charlie Brown since he was such a block head while still a pup. Not on the lack of smarts but due to his head was about as big as the rest of him when the wife brought him home.
All the wife needs to tell him is "watch" and you ain't gettin any closer to her. Bottom line, don't mess with mama period.
As far as a hunter, he will go get anything he isn't called off of. He is fast enough to run down a squirrel in our yard and has caught up to deer once out across our back pasture before he learned we don't chase the deer. His favorite activity is a good ol fashioned rat killin. He knows when we start to clear out the farm shed it's time for some fun as there are always a few mice or rats that can be found. They don't stand a chance. He don't even like gofers and will stop from a dead trot and dig them up even if it means a 4' hole. I have never seen anything NOT like a rat like he does.
I use him to track if needed, as he simply needs to be told "find it" and he is game on, no matter what it is rats, squirrels, deer or hogs. I use a long leash and sometimes I am simply along for the ride. I don't let him go after the hogs full tilt as the wife would shoot me if he got cut up. However once they are on the ground he always wants to get in on it.
Here he is having fun with a 250+ pound boar I got last spring,
He yanked it out of the bucket of the tractor 4 times before I managed to get it up off the ground high enough he couldn't jump in and get it.
I have had dogs all my life it seems. Two before Charlie here, were Golden retrievers and were about as great of companions and friends as one could ever wish for and are dearly missed. They were gung ho for anything outdoors. Ol Charlie here has been an exceptional companion as well.
