IMO, always look for a breeder that titles their breeding stock. Whether it be IGP, Obedience, Agility, Scentwork, Conformation or hopefully a variety of these things. But they need to be proving that their dogs are capable of handling the stresses of training and trialing in multiple venues day in and day out and prove that they have STABLE temperaments. This includes accepting neutral strangers (judges) in appropriate environments. This doesn't mean they need to be friendly, but they need to be at minimum neutral when their owners feel comfortable. This is something that believe it or not, can also be judged in conformation. When the judge approaches to examine your dog, they are ALL in your and your dogs space. Then the judge lays hands on the dog and the dog should tolerate it. It would be no different than if they were at the vet. Because you, the owner, tolerates it and your behavior is telling the dog that there is nothing to be worried about (saying hello to the judge, feeding the dog etc.), they should too. A doberman that shies away, or growls, or worse... bites in this environment is not a stable doberman.
Honestly, a nervy doberman is not going to do good in any of these venues so while we may not have a way to title/test that is specific to a doberman other than the WAE (title is WAC) I would encourage prospective owners to seek and support breeders that do title their dogs as one of the ways to help preserve this breed.
