What I can find on my search on the internet is that a brown/red color can happen in GSD. Some nice pictures and an easy reading about the genetics you can find in the links below.

p.s. I speak about pure GSD who have VS pedigree. p.s. http://hauspharao.com/colorgenetics/diagHQ.jpg this are pure GSD colors. other genetical in pure GSD not can be. but ... in example about atypical color are only USA dogs photo- realy question why this example not can find in european pure GSD with SV pedigree. |
We also know that not all breeders are always honest about 'not normal' pups, and sometimes they just disappear as if they never were born... what you can't see in my dogs it's simple not there.

like this brown CSV, why mutation have and sarlos anatomy? not to strange? :roll: p.s. I speak with this breeder who know all " who hapened in breed" and say all who is who. and I believe in they info, when know they are good breeder who realy love breed and make all for breed goodnes. in this case I not believe in falsh info about GSD with SV pedigree |
p.s. this jpg abouyt GSD color are DNA testing result about this, I think if exist atypical color DNA testing mas say this too.

Maybe I'm wrong but if I assume that red may come from GSD than I can also assume that CsV may also show up in blue color, white color, all black color, etc, since all these are colors found in GSDs..... but in my limited experience and knowledge of CsV I have not seen one like this in any gallery or history, and if I saw one today I would also think it was a recent mix..

Coat color is an interesting subject, and what I did understand not an easy thing to understand.
There are different genes for coat color and patern, and the mixing of these things do make the color of the coat we actually see on our dog. There is a gen for the coat color in GSD it is B (black) en b (brown) B is dominat over b BB is black Bb is black bb is brown Then there is a patern of the coat, wolfgrey and sable are coat paterns. This means those genes wil tell where the black/brown color is showing on our dog and that on some parts of the dog the black is not visible. Then there is a dilution gen...... When you coat color is black geneticly it wil show on the dog as a blue color. When your coat color is brown geneticly it wil show on the dog as a lighter version liver? Maybe someone here can tell us more about this thing coat color, as i find it very hard stuff to deal with. And there can always be a spontanious mutation of a gen...... like the Panda german shepherd. |
GSD are a, at, aw, as, A
like are in books aw x aw born only aw - wolf grey A are only teorical black when in dogs are a black dogs a x a - all black aw x a - wolfgrey at x as - black and tan this are color genetic who not change anatomy, ( bones, head type and moore) p.s. Your dog can realy help to DNA testing in this case |

I'm just wondering, because this does not necessarely have to be the case. If there is any inbreeding (like in this case there is), then it does not need more than one individual to introduce a new trait (recessive gene) into the lineage/breed. Because due to inbreeding, this one individual may end up appearing in both parent's sides in the pedigree. -And in such situation, the chances are that some day in some certain pairing the recessive gene gets doubled, and so it appears in the phenotype of some offspring. Of course there CAN be more than one "oopsie daisy" (a mix up by accident or on purpose) taken place. But I just wanted to point out, that if suddenly some weird looking puppies of homozygous recessive genotype (like in this case bb / brown coloured) occurs, it may very well be a result of only one "oopsie daisy" that is just doubled in the pedigree (comes from both parent's sides). Recessive traits may jump over several generations unnoticed, and it may take time before (due to the chances of random selection of the genes) some day some certain individual will inherit two copies of this recessive gene, that once came from possibly only one certain anchestor who passed it forward over several generations. |

We all prefer not mix CzW problems with other breeds, but seems like in this case, other breeds are getting mixed in CzW breed without we know about, and it could be simply tragic. We only need to know if there were more Saarloos living there than Dvorak itself. |
CSV GSD origin

Recessive gene, that would be shown by puppies of Sibir and Thalia (and nowhere else!) could be introduced by either Fallko, or Mona, because they are the common relatives. Or by mixing, and declaring false parents, but if we do not accept the possibility, that Fallko or Mona were mixes, then the mixing would have had to occur twice at least, once for Thalia and once for Sibir or one of his parents. |

and .. very easy make pedigree for falsh dogs when not mas have DNA testing in puppy but .. genetic not lie - we can see diferent in anatomy not only in color. |

Amber eyes vary from light brown (overlapping with the lighter eyes sometimes found in black-pigmented dogs) to yellow, yellow-green or grey." Well, although their information is not wrong (hopefully), it is quite incomplete, so it needs to be taken accordingly. Otherwise thanks for the link, it is interesting read. |
