How well do you know the standard? If someone asked you to describe your dog's conformation strengths what would you tell them?
I show my dogs in conformation and know their strengths and weaknesses. When I am planning a breeding I can talk explicitly with the owners of the dogs I am considering about what I am looking for and what my dogs faults are. Part of being able to do that is having gone to enough shows and seen lots of dogs in person to learn what I was looking at.
As for performance competency, if you aren't actually working your dog how do you know it is able to perform the job. What are criteria are you using to measure proficiency?
