Finding a straight walker hound to run hogs now days is rough. I was raised hunting behind some awesome treeing walker hounds all my life and they were hell on coons. The problem with them on hogs is exactly what's said above. You will get to know the neighbors of all the places you hunt very quickly. You will know all the county roads in a 20 mile radius from where you hunt. You will have dogs that will flat blow the doors off your box, burn a hole through your tailgate and take out like a rocket. You will also see many hogs while on your way to a race 5 miles away. And finally, you will go home many nights without seeing a race end with a hog on the end of it. I think a Walker hound is the most attractive specimen of hunting dogs out there ,but for CATCHING hogs there's much more practical choices.
good post...you will be hunting hounds and not hogs...
