was told by an oldtimer,they used to enter their young dogs on old brock for a sesson or two ,even before they'ed see charlie.he said it would teach the young uns to stand and bay rather than just mix it with brock,for he was a formidable opponent.and when they would work fox,rather than kill it to ground nine times out of ten charlie would bolt rather than be dug to!not a bad thing considerating they had no locaters back then
