Liver Puppy in PDB ad? - Page 4

It's sobering reading looking at the list of dogs that carry the liver and blue genes! My pup has carriers in her pedigree on both her mom's and dad's side (Jeck v Noricum, Keno von Celler Schloss and others.) Thank goodness Ursus isn't known to be a carrier, and the other dogs are so far back, I doubt I have anything to worry about!

What is referred to as a "chocolate" is actually a black with a liver recessive. Similarly, I have seen solid blacks carrying the blue recessive. I have also seen sables with a blue recessive (at 8 weeks, they are sort of a powder-puff blue).

The brindle markings may occur on dogs of any color. I saw some of these in California during the '60's and 'early '70's. There was also a blue AKC champion handled by Denise Kodner.

I believe that blues (I have no experience with livers) are a lot less rare than some believe. Perhaps, they just aren't reported and not registered.

In the 60's, I saw blues from imports Ulk Wikingerblut and Bernd Kallengarten (and son Santana's Man O'War).

Of more contemporary dogs in Germany, we get blues through Uran, Eiko, Karly (and son Jello), etc.

mystere,

that link spoke of the "Very Rare Irish White Spotting Gene"

Is that what those Panda Shepherds probably have?

You're right Mystere, it has to be a new mutation.... or a very elaborate hoax!

The white spotting is quite different from irish spotting in appearance but the important difference is that, unlike irish, it's inherited as a dominant.  This type of spotting was not known in dogs before this, so has to stem from one of the parents of the original.
