I have a female with very similar lines, strong czeck dogs with pike slipped in on the top line. She is very intense...some what OCD even. But she is also a very loving family dog. Great drives for any scent work be it drugs, explosives, or tracking and trailing, and still able to crawl in bed with the kids and be safe. She is pretty posessive of her crate and her toys and tends to be slightly dog agressive towards other females. I absolutely love her, I paid more for her than any of our other dogs, but well worth it. Probably not a good first gsd for someone, but for experienced handlers I love the pedigree.
