Canine Good Citizen. Once your dog has taken all obediance classes, you can take this test. It's basically a certificate saying your dog is a good citizen and behaves well in public. Such as it can sit and be pet by strangers and be OK and lots of other things. It does have to pass EVERY part of the test or it can't get the CGC certificate. it's a WONDERFUL thing for your dog to have. Hope that helps!
Oh yeah, just about any training facility is certified to give you the test.
