You'll have a hard time finding anybody who does this anymore, it used to be common practice years ago when working hogs with dogs was a necessity and not a sport.
I figured as much. This guy was real old school. Looking forward to getting a dog from him in the future.
His bulldogs are more herders and livestock guardians than catch dogs.
Even those old stock dogs were required to catch when told. I've always thought it odd that some want to accentuate certain parts of the duties that were required of those dogs while minimizing others...
