Guess my next question is were these breeders newbies?
Both were handlers, one was handling a clients bitch, other I believe a breeder/handler. Not new. Wish I could give you an answer but I'm not sure the answer to your question on what drew the judge. Ripley was the most fit in my eyes, I've been conditioning her and trotting her every evening for the past month on top of her normal exercise. Sometimes the judge is drawn to handlers because they think "this one must be good" if it has a handler on it. Sometimes judges are drawn to size... some prefer big, some prefer small/refined. And everyone else in the middle picks the most correct bitch

Ripley was between two large bitches and then next to Derek...so...

probably didn't help and made her look small.
Rip has her faults as they all do, they are fairly minor and nit picky. She has the same issue as almost all dobermans today have: she could use more angle on the upper arm, putting her front legs more underneath of her. Her front pasterns could be a hair shorter. Her muzzle in the front a hair more square... she has an extra tooth. She's excels in that she is square, has a level top line, a beautifully correct rear assembly and is a lovely mover because of her overall correctness. She's really hard to nit pick but I am the hardest on her... I live with her! But that is what I've been told about her when I had a breeder judge grade her. I will also add she has one front pastern (only one) that slightly turns out, I believe it was an injury as a puppy from mom that healed weird. Easily fixed by turning her foot when stacking and sometimes she fixes it herself too so, not anything that is her fault structurally. If she was like that on both I would lean towards that's her conformation.
I've been told two things by longtime dobe people on why she hasn't finished already (and in the nicest way possible): money (it costs big money for big name handlers to take your dog and travel around) and she's "too standard" (sadly but honestly)

where she uh, sticks out because she looks different and isn't FANCY. It's also really quite normal for bitches to not finish until 3-4, there's just SO much competition in addition to waiting for them to mature/fill out. Paula was just telling Derek to move her to Open class because she looks very mature now. Derek joked "finally!" and a bunch ringside were sympathizing saying their dobes look better than they ever have at 5... Anyways, I could say more on what I saw but I'm not one to enjoy getting my head cut off so I'll just point out what is wrong with my dog

. Someone is always listening.
