wow That's so cool. I read a story. It wasn't a GSD. I think it was a blue healer but this rancher went it to make this bull go into a corral swinging a bucket. The bull got mad and charged him. He knocked the rancher down and broke his leg. This dog raced up and latched onto the bulls nose. The bull swung his head around again and again throwing the dog around in the air. The dog hangs on until the guy crawls out of the pen. Not a GSD but, aren't loyal dogs amazing?
