any working terrier worth its salt,will change its working style to suit the quarry,I've always kept bitches,(everyone could kill a fox no problem)Id expect them to stay to what ever they was shown, wouldn't keep a dog that could only do one thing...I've seen enough bitches half the size of a dog,stay and complete the task when a male has spewed,up and down this country in places you wouldn't drop a free ads special in..
if I was ever to start up again,then a black dog and would be my choice?
