BLUE BULLDOGS

Genotype for Blue Gene: [dd]

Blue Bulldogs are diluted black dogs. The blue/grey coat should be shiny & look grey against black objects or in the sun unless it carries the Seal gene, which would show maroon or other color undertones. These dogs may or may not have a fawn undercoat when the hair is rubbed backwards. The nose, footpads, & eyeliner are always blue/grey, which can vary from light to dark, not to be mistaken for black.

Note: it is unfortunate that we have to register our blue dogs with color designations that dont fit our colors. Therefore it is extremely important for Breeders & Puppy Parents to use the descriptive terms in their dogs names such as "Lilac Passions", B"Blu Dreams", "Chocolate Sensations", "Black Beauties".

Blue color in dogs is no more than a Diluted Black dog. Contrary to popular thinking, the Blue gene is really NOT a blue gene. It is a dilution gene which can dilute any color, including chocolate. For the Dilute Gene to make, if you will, a true blue dog, the full BLACK base has to be there to be diluted. True blue is a Slate Gray Color, although the black can be diluted to many shades from charcoal to off White with a blue base. ALL of these colors are genetically blue.

The nose, eyeliner, and pads should be self colored(color of the hair), except in the lighter color dogs where the pigment is usually a darker blue than the hair. The eyes are often light gold, green, blue, or gray. In addition to the nose color, DNA Color testing will reveal the "dd" alleles in TRUE BLUE dogs. Each parent also contributes one of their two dilution factor genes to their offspring - either a dilute (d) gene or a non-dilute (D) gene. Dilute parents (dd) can contribute only a dilute (d) gene and non-dilute parents (DD) can contribute only a non-dilute (D). Dilute Carriers can either contribute a non-dilute (D) or a dilute (d) gene. For more info, please refer to the Rare Color Chart.

Dilute/Blue

DD, Dd, dd

The gene d has had recent discoveries and has now been renamed d1. This mutation alone does not account for all dilute color phenotypes. A second and third dilution MLPH variant d2 and d3 has been identified. Still, two copies of any of the three dilution variants, or any combination of two of these, are necessary to lighten the color.
