I have a pup from working lines that was born with short tail. I've been told this sometimes happens in BC's and just wondered if anyone knew of any good trial dogs that were born with a short tail and would love to see video or pics of them. I'm wondering if it would affect this pups potential in performance in any way? When I say short I mean about half a tail length with no twisting or deformation of vertebrae at base of spine but only about 3-4 disc's from base.
