Sable Merle & White

The Collie parent-club guide describes sable merles as appearing sable with varying degrees of merling. The Collie standard describes white markings commonly on the chest, neck, legs, feet and tail tip of sable coats. These are Collie examples; the Cardigan Welsh Corgi standard does not permit merling other than blue merle.
