She's very cute! I see you're in Williamsburg... I'm in Des Moines!
From the early photos, it looks like she's a bit down on her pasterns, are you giving her any vitamin C? 1000mg a day might help her come up on them, and help tighten the feet.
I show in AKC, I'm a member of the Doberman Pinscher Club of America and the Doberman Pinscher Club of Greater Des Moines. We're working on preparing my red male for his CD, but it's sloooowwww going.
You will probably have more fun in Obedience and Agility. Showing Dobermans is very difficult, and very political. It takes a really good dog (or a really expensive handler) to be successful at it.
