This is a no brainer. Please don't breed her. No offense, but the fact that you're even asking us proves how little you know. I'm assuming you're not a GSD breeder, otherwise you wouldn't have asked. Which means you're a back yard breeder. Please spay her. Let the so called "experts" do the breeding. Sorry for being blunt. If your dog is really a "psychopath," we don't need those characteristics in the gene pool.
