He's a Berger Blanc Suiss Shepherd. I think they were first recognized as a seperate breed about 20 years ago. Before that they were simply part of the German Shepherd breed.
It's definitely not something I would start without finishing, but the more I look at it, the more I think my dog just doesn't have the personality for it.
I was watching a video by a big time dog trainer talking about what you mentioned. He basically gets a feel for the dog, and he won't train certain dogs for bitework because they just don't have it in them. You can make them do it if you really want, but it's just not their thing and you can end up really messing up the dog. He's looking for dogs that are suited for it, and able to do it without getting stressed or overly aggressive and screwed up.
I might go check out a club, but the more I look at it, the more I'm thinking it's not for us.
