does your terrier try to enter earths and wholes when your rabbiting,if so then get your self a collar and a spade and ask your local gamekeeper 2 come along and supervise you,and just see how the dog does in a proper eath, he will either stick with his quarry or come out,and if you find you are finding it hard to reach the dog ,atleast then the keeper will show you how. theres only 1 way to learn bud and thats just to have a go at it, i did by myself and i havent looked back.
Look at the picture, if his dog enters an earth and works a fox i'll eat one of them dead rabbits raw!!!
