Cheers for the reply, and genetics are funny old things, as you know. You could do the same breeding again, and end up with a collie. if that makes sense? Percentages are not the be all and end all. I mean on paper a 5/8 collie shouldnt be able to get near some of the stuff that Adonis does. I know what you are saying in that physically when put to any runner, the pups should have more to offer than himself, but im not so sure, well, not for ANY runner, as like we have said before, speed isnt that important, as long as the dog is 'fast enough', and how fast, fast enough, is, depends on land /
