What is the physical description of a blue nose pitbull?

"Blue-nose" is a fad street term for a blue dilute dog. Both the dilute blue gene and the "rednose" gene are simple recessives, caused by two entirely different genes, that "wash out" coat color, or "dilute" it. The blue gene dilutes black to gray, not just on the hair, but on skin as well, so a dilute blue dog will have a slate gray nose pad, lips and eyelids instead of black.
