Anyone know what lines Wildhaus are?
Mostly West German, with a bit of DDR a few generations back. Occasionally crossed to Czech lines with some litters, and have a 1/2 Czech, 1/2 WGR youngster who will hopefully join the breeding ranks in the future.
As for the kennel mentioned, I know nothing about them. Though have to admit being skeptical about a breeder of "working German Shephard's
Dog". They didn't own Tom zPS, and that is a bit misleading on their website unless you read the blurb that says he is just who some of their dogs are linebred on.
As far as Tom, he is behind many of the best Czech lines. Our new addition's dam is linebred 4-2 on Tom. So far with Jazz, there isn't anything not to like. Very good drives, but excellent off switch (surprisingly so for her age actually), very hard, exceptional nerve, not too independent, not too people focused, directable but at the same time with a bit of stubborn streak and desire for mischief. Excellent focus and desire to work. At only 5 months old there is only so much that can be seen yet, but so far so good. This is my only really significant first hand experience with Tom lines though.
For more info on Tom lines, contact Cliff. He has tremendous wealth of knowledge on these lines, including having owned a Tom daughter and currently owning an older full sibling to our Jazz.
