How can she protect if she is restrained?
Well, did you train the dog to protect? Most of us just need a deterrent. Even within a crate, the booming barks of a GSD can send a would-be burglar somewhere else.
Dogs with SA are a danger to themselves. They can eat things that could kill them. They can go through windows to get to their person. They can do enough damage, that people may give up in despair. When, a crate could have kept the dog safe. The crate does not have to be permanent. If the dog becomes less anxious with time, it may be ok to give the dog some more freedom.
I know some places culturally, have a different view of crates. But for dogs with problems, they can be a life saver.
