I am planning to attend a seminar coming up pretty soon on the subject of "Proofing" in dog training, and was curious what the rest of you might think of the topic as it pertains to dog training?
That is - how would anyone define it? Why is it needed (Or is it)?
How does anybody do it (if you think it is needed)?
Is it something just for those who show their dogs in some show/trial or do owners of "Ordinary" pet GSDs also need to think about it?
Please note that there are some very strong opinions on this subject among many trainers so lets all keep the discussion very civil and polite.
