I have a female GSD puppy of 16 months old , worse dog I’ve ever owned and I now have a broken wrist because of her , she decided to bolt with me and her on a leash , chasing a cat who suddenly came out of nowhere and ran behind us , I was dragged by her on a concrete car park floor etc my leg all scraped and I eventually fell onto my arm and wrist. These GSD dogs are a nightmare even when training them they need to be trained every single day.yesterday she decided to start barking none stop at this nasty French woman, who was being verbally annoying to me , it was this woman’s cat who ran behind us and she comes out of her entrance building rattling her set of keys , and that’s how I fell last time? As the cat ran behind Me and my dog, and my dog went crazy, ! In any case I think GSD dogs make terrible family dog, terrible companion
