Ahhhh.... but what if I said that I believe all dogs posess the same basic fundamental skills/instincts....
... if one dog can smell one molecule out of a thousand and another can smell one in 1100... I say they can both smell a hog

I've personally seen more trained hog dogs than purposefully genetic hog dogs.... as far as dogs I consider true hog dogs...
I believe we can tweak a dog through breeding to "start earlier", "hustle more", "take a colder track", etc... but I am really startin' to believe at some point you just got to pick one out and put the time in to make it great.
