Gustav, you are absolutely right.
But I spent the past hour or so looking at Jeff Oehlsen's dog which is this one (correct Jeff?): www.pedigreedatabase.com/gsd/pedigree/669849.html
. Now, I only had half the pedigree to work with since the sire line is an unknown. I do not want to go onto the working-dog.eu website right now, because there is a thread going on on the German working forum that it passes on viruses. A lot of people with IE had a total crash of their harddrives after visiting that site. So, I am going to wait a few days until it is clear again. Jeff needs to come on here and say if that pedigree is accurate or not which is often not the case here. One line that can't be right is the one behind Nory D'Echalon, out of Juran vom Wildsteiger Land and Quina Arminius (sister to the famous showline VA-1 Quando von Arminius). The whelping years do not match. So, I ignored that part of the pedigree as well.
Now Jeff, you think that Canto and Quanto do not play any role in your dog's lines. And based on this pedigree I am telling you that you are dead wrong. I counted Canto von der Wienerau 23 times on half of your dog's pedigree and Quanto von der Wienerau 11 times. Now granted that I might have miscalculated a couple of times (I do not have the patience and time today to do over it again), that is a lot of inbreeding. Gustav, do you have time to calculate the inbreeding coefficient?
Jeff, I learned a lot about these French lines and I wanted to thank you for that. Apparantly two prominent kennels - du Val des Hurles Vent and de Gerbe de Grenval based their whole lines on Walter Martin's old Wienerau dogs. To name a few: VA-Sam, VA-Reza, V-Xando, V-Luno (who is a sibling to the famous L-litter) and the great Dixie obviously was exported to France after Walter was done with her. Marko Cellerland only appeared 3 times in the half pedigree and Mutz 5 times. That leaves room for one conclusion (and Gustav, please correct me if I am wrong) that these French ring lines genetically have much more in common with the German showlines than the workinglines and/or East German or Czech lines. Jeff, the mother of your dog has two outcrosses in her pedigree: Yoschy vd Doellenwiese and Aly v Vordersteinwald (sire of Mazurka). So, that pedigree is definitely a mix.
That is why I do not understand why people scream foul when breeders want to mix lines, show or working, Czech or working, etc.. Yes, there is not much to expect in the first or even second generation, but patience and persistence is a virtue.
Now, at this point I feel the need to mention the famous glasshouse again, you know what not to do when you are in it. No cussing, please!
