BLUE

---

Overview: 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".

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.
