I saw your thread about searching for a schutzhund prospect. I'm technically waiting on my pup from them, but I recommend Weberhaus. Malinda and her husband are very helpful and courteous. They work their dogs at their Schutzhund club and pay special attention to the health of their dogs. She mainly has Czech lines, with some DDR and WGWL thrown in. Their website is here(they're doing maintenance right now), they also have an active facebook page.
