They should find , trail & catch solo not with other dogs. If it barks its a bay dog. I've caught some big rank hogs with my male. He might be 200 yards out or a mile out.
if your dog is a mile out and is caught on a 275 pound boar then there is that possibility he will overheat or get beat up pretty bad by the boar...is he a solid catch dog or is he a smart catchy dog that knows how to keep one stopped and only catch as needed?
a big boar that is fresh can beat a dog pretty bad that is a solid catch dog or the dog can overheat holding a big boar that is a mile out...
