Donna @ Eclipse Shepherds does. She is an ASL and WGSD breeder in Minneapolis MN. She will openly admit that her dogs are not typically suitable in the Schutzhund ring so not much help if you really want to pursue that-but her dogs excel in rally, agility, and UCK obedience rallies (she has had several therapy certified, service dogs, and SAR dogs from her past breedings) so it depnds on where you fall on the spectrum of ASL vs GSL vs WL.

If you lean WL Vinnie's suggestion http://www.kulladogs.com/ is a great kennel.
