RE: German Shorthair
If you like NAVHDA type dogs, try Shooting Star Kennels, or SharpShooters.
You may try Brenda Roe, her dogs go back to Hillhaven Hustler and are known for bidibility, calmness, quietness, and just all around nice gsps.
For hell bent for leather types, big running and gunning gsps, try Rabidou dogs.
For the record, BLUEGRASS GSPS (and I don't know this guy) has two of the breeders recommended (shooting star and Brenda Roe) right in that litter.
