The GSDCA is also affiliated with the WDA - a Sch and working dog club. The GSDCA also is heavily into obedience and does a lot with it although as stated their major thrust is toward the conformation end.
Actually the national club (GSDCA) does do a lot with obedience even featuring the obedience GSD's in at least one issue of The Review (the monthly magazine published by the GSDCA) every year.
They also do a lot with working dogs through the WDA affiliation. They have a lot of information on herding and even Rally. Anyone with a GSD should definetly look into the GSDCA and esp. Their web site - lots of great information for GSD owners and potential owners. www.gsdca.org
Of course there is a lot of conformation stuff there as well, but if anyone is not into that aspect of our dogs, just ignore that stuff.
