RUNNING COMPANION DOG - $1 (LEWISBURG, KY)

I need a very specific dog that will behave and stay on a farm and run with my wife and teen children down long country roads.
The intent is a dog someone won't mess with, thus that someone won't mess with my wife or children when they are running.
Needs to handle the heat in the summer as we run year round.
Can't have prey drive as we have cattle, sheep, horses, chickens, etc.
Looking for something like a Doberman, Dalmation, Rhodesian, Catahoula, etc.
Must be a level headed dog with good recall.
NO PUPPIES, JUST ADULTS.
Please don't try to dump your mixed lab and pitbull, etc.
Only contact if you have a true candidate that you would like to live its years out on a farm with a serious task to accomplish.
