Some good kennels suggested. I would try Locheil and Beesting as they are up north. Both are lovely people and would openly go through the health testing that has been done. They would be excellent starting points as they would recommend other good breeders if they had nothing coming up. Another couple to recommend are is Pat Ward of "Starside" Border collies and the Wiltshires over Leeds way who have "Caleykiz" Border Collies.
