What you have to realize is that a lot of folks in SF are AR, especially in dog parks. There is no test, written or oral.
There are lots of dog shows in the fall and winter in the area. In October there is two back to back specialties in Pleasanton. A specialty is a single breed show. So a rottweiler specialty is a show with just rottweilers. Also check out the German style shows, which is also just rottweilers. USRC clubs are in the general area and put on a couple of shows a year.
If you get to Crissy fields you might see our own LynnS with her bitch, Bella. Bella will have a big ball. She can give you lots of info about handling classes in the area and such.
