All types of dogs... DDR, west german show lines, American show lines. No clear plan to any of these breedings... just kind of mixing and matching what they have to produce puppies.
The breeder says all their dogs are "prime of example of working dogs", but none of them work or have any working titles, at least no mention on the website. Just seems a little off the way they describe their dogs.
There's much better options in your state.
