fearing another time-out , In the same magazine there is an article which would be exactly up Wildos alley talking about Leistungslinien after 1950 in the SV , talking about Bernd and Bodo and there offspring , Nestor Wiegerfelsen , Rolf Osnabruckerland (the later two being the sub group which is the Show lines of modern day)
Nestor -- to Immo Hasenfang, Axel Deininghauserheide (American show lines) to Alf Nordfelsen , Veus Starrenburg, Nico haus Beck, to Nanouc , Boris, Flori to Fero , over Troll and Timmy to Aly and Yoschy .
To complicate things because Wildo was asking what dog represents each founding group and that would be difficult because some of it you can SEE and some you can feel through the training experience . Example Troll and Timmy von der bosen nachbarschaft (essentially Troll and Timmy of the bad neighbourhood) . Troll represents the BERND side of his pedigree in body type and in behaviour and thresholds more , and his full littermate Timmy represents the Nestor side of the pedigree - being lighter in build and sharper, more reactive.
you have to know the dogs . It is not simple . You can make a life study of this and still only scratch the surface .
