some of the best hunting dogs I have owned were a little on the shy side...
some meek and easy going dogs were ferocious on a hog...
can't stand a hyper dog but...
some of the best hog dogs I ever had were very laid back with brains to spare...and when the tailgate dropped they left out in a dead run and were hard hunting, hog finding machines...
even when the dogs were linebred tight an unusual colored popped up every once in a while...
even without bringing in any new blood the dogs hunting ability improved without new blood...
I agree with these.
