Pass them on mate, it's the only way. I know how you feel, every litter I've bred i tend to keep the worst one !!!. It doesn't matter how long you've been doing terrier work or how many litters you've bred if you can pick the best pup in a litter at eight weeks old then you're a better man than me. The only thing you can do is give them too good friends as I've already said and have a hand in there upbringing and entry, after a while of doing this you'll feel like you've got a massive teem to call on should the need arise and a much bigger gene pool to breed from which all should be properly t
