Kelly and Duke had a beautiful litter which included a handsome pure blue boy named Rocky that you can see at about the 1:20 mark.
Beauty and Shazam had this wonderful litter of pure blue and pure black puppies (two of which we held back for our breeding program). Both colors have beautiful sleek coats with no brindling. We refer to the blues as blue grays, whereas the lilacs we refer to as silver grays. Whereas the black brindles sometimes have a brownish hue, pure blacks are a midnight black with not lighter hairs, except for a small white patch on their chests, and possibly a tuft of white hair somewhere else on their body.
