The females I've owned always seems more inclined to defensive aggressive type behavior. Not vicious, but annoying.
Had a male German shepherd lab mix, stray puppy from a pack of strays on a reservation from Dakota. Best dog ever. RIP Harry.
Just spend time with your pup to socialize them right. Most don't fulfill their 'pack' duties to their dogs, then they misbehave
I had an awesome female white German Shepherd when I was a young adult, we had trained her to stay with us and on our land, she was a damn good dog
Intelligence of breed probably helps too
