WTF.Your half breed might be a world beater mate but i wouldnt give you tuppence for any offspring ,no matter what you put it to .One offs are usually just that .If i cannot trace back 3 generations of good ,honest workers then i dont want it .Nothing stopping joe public getting a terrier from non workers ,and theres plenty about , as long as its not used to further dilute the blood of honest lines .If you stick at the digging mate and want honest workers you can rely on ,you will realize the truth of what im saying OR you will always be a messer , hoping for a worker from this and that mating
