True bi-color gsd whats the story, pics ect.?
Christine Kemper (fountain of GSD knowledge and very nice person):
Some bicolors have tan on the face, eyebrows, and chest spots.
is “tanpoint” – the same color that you see in Rotties and Dobies. The
masking gene modifiers cover up the tan brows and tan on muzzle and
face and chest usually in GSDs, to a greater or lesser degree.
blanket saddle back or a dark black and tan is a dog who has at least
one copy of the “creeping tan” or “saddle” modifier gene that causes the
tan areas of the dog to expand as the dog matures and then also carries
the black recessive.
bicolor without the black recessive (tanpoint/tanpoint with no saddle
modifier) is sometimes called a “bright bicolor” –especially if the dog
does not have a many of the dark masking factors. A bright bicolor will
still have tarheels, no tan on the underchest, and toemarks–although
the toemarks might be faint and somewhat hard to see.
