After much consideration and discussion with my wife, we have decided to go with formal obedience to start with, rather than ring or PSA.
So, any formal obedience trainers in the Sacramento area? I have found one with an AKC obedience club, but my puppy is only half GSD and they require AKC papers to do any work with them whatsoever. There are lots of pet-type trainers in the area, but that's not really what I am looking for.
