I have a GSD and was horrified to read this and the lack of responsibility of the owner, I am afraid I don't care how sweet the owner is she obviously has no respect for animals including her own as she is putting them all at risk. GSD are highly intelligent and are very habit forming (except mine who can hardly remember where his food bowl is) they need to be controlled and taught thing which obviously she is incapable of. I would report her to the local animal welfare/dog warden and also take all vets bills to her to pay. 1 attackis a fluke serveral is irresponsible and obviously her fencing was not erected to keep a GSD in.
