I've known the Asheley from back in her GSD days. (Vrijheid Kennels) Her foundation female is the DS in the early Ivan Balanabov videos. If I were to get a DS, I would absolutely go with Van Leeuwen, but I'm looking for/want a different type of dog for sport. I've owned two DS. One was a striped pup from a Mal x DS litter, he ended up a narcotics PD. The other was super sweet guy, fun to live with, but very very little prey drive. He is now in an agility home. Both were from KNPV lines.
