Brindle German Shepherd Dog - Page 3

I still see all black as Dominant. K is on another location and has to do with pattern. I'm still behind on brindle though. Would it be hidden on a red/buff/cream/white, the way sable, bi color and saddle are? I still see a lot of web sites failing to explain that solid and black are 2 different things :-).

On the dogs from this database that were linked to, Beowulf is the only brindle with linebred decendands we can see. Too bad we don't have All the dogs ever born registered with pictures on this site. :-)

I would not be surprized if a brindle showed up in the GSD today. Hopefully they will document it well and we all get to read up and see pictures.

What about this dog?  Friedo vom Schlabendorf 
 http://www.pedigreedatabase.com/dog.html?id=491738

Good find Beetree,


Friedo looks to not have any descendants .... Too bad we have no image of his dam. He also looks to have a sadle with the brindle on the tan parts when the contrast is inceased on the image. Today I read they call that "Trindle" for Black/Tan/Brindle. some posts on this thread are great but you have me doing  a lot of homework. The color testing lab sites don't allways tell us everything they know either.

All the genetics and possibilities make my head spin....LOL If one goes by the chart from Vetgen, a hidden brindle could be possible....at least thats what I read out of it.

I wrote them to see what test of their list for GSD coat color testing they suggest would show if there is the possibility of a hidden brindle. See if they write back; I might just send the girl in for fun. I know one thing for sure, she is purebred GSD.....nobody jumped the fence here....LOL

I would love to know if any "proven" as claimed, currently living, brindle GSD's, can be traced back to "von der Krone" origins.   Also, I say that's where the reverse mask has a start, too. That's my theory any way.   And I think those dogs were a strong originator of the herding genetics/instincts for the breed.  I would love to be corrected if somebody knows about this.

A thread could be started on reverse marks. I knows others have spoken of it before.
The following dogs in the US had it
Jem of Penllyn 
Hollamor's Judd
Ona of Edgetowne
Gernda's Ludwig
and
I saw it a lot in the DDR lines and Working lines.
They also have some good looking dark sables with lighter circles around their eyes like Lord's Dam.
Lord vom Gleisdreieck

Note those Bicolors with lighter masks. 
Elkoor, If you test please let us know what you find :-)

I klicked by no specific order throughmy bitches pedigree to find this dog wayyyyy back. http://www.pedigreedatabase.com/dog.html?id=976
It not only looks like he has some brindle showing on his hind legs, but in the comments it is mentioned a wavy spinal coat. What is so interesting about it, my bitch shows exactly that decribed wavy spinal coat, which forms a zick-zack  /\/\/\/ line over her back. She is also the mother of my striped pup.

Brindle + aa (recessive black) - dog will be solid black (recessive black does not allow the production of phaeomelanin in the coat)

Except for "bleedthrough" blacks... Do you think bleedthroughs are actually brindle? Even so, what explains the parents of said dogs *not* showing any brindle (even if the parents aren't black)?

I still don't think that we'd see the brindle coloring "hiding" in black GSDs--because there are very few dogs who have a full line of solid black ancestors. And the brindle shows up--in some way--in all the other agouti patterns. So it doesn't make sense that it would "hide" that way--you'd see it in every litter, just about. I think you'd see it as an odd looking sable, too, in sable pups.

In addition, most brindle GSDs that are photographed come from either black-tan parentage or unknown parentage. The lines that carry the most incidence of recessive black don't seem to be throwing brindle pups... So, for most cases, I think it's not a case of a normal transmission of the K^br gene down through generations of GSDs--I think this is extremely unlikely. I suspect either mutations or a recent brindle ancestor (Dutch shepherd, especially, nowadays) in almost every case of brindle "GSDs".

Got an answer back from VetGen (fast!) and ordered the suggested test. Now the waiting begins....LOL

Blackthorn, the link to that article was good and explained a lot. (took me while to understand it though)
1. red/cream dogs will never express brindle but can carry it and it will be seen in their black base progeny.
This means a white cream GSD could hide the brindle. Great Danes do not carry RED. They are black based so brinddle can't hide on them.
White/Cream shepherds can hide patterns like bicolor and brindle.
3. Some brindles turn all black as they get older. (Tricky)
4. the role any/all genes have in the amount of black in the brindle is not yet understood.
