We were informed last night that male GSD are more "people" protective
Female GSD are more "property" protective.
I've heard/read/experienced the opposite. Males tend to be more location protective...marking, barking, etc. Females are more pack protective. Don't mess with their people. Males are goofier.
She stated that's why police dogs are male.
From what I've heard from the police offices I know, males are more intimidating with their barking and usually have better "bite." But I've had more than one Shutzshund person tell me that they recommend males for the beginners because females are more serious and less forgiving of mistakes. They don't have as strong of a grip as males, but they are more serious and easier to focus. Males cafn also be slower to mature.
Now, there are exceptions to every rule, but that's what I've been told. I've always had females. It wasn't until seven years ago that I got my first male. My dad actually asked me why the heck I would want a male...they mark, they roam, harder to train, etc.
I ended up LOVING the males. My boys are mama's boys.
They love me in a way my females never did. I realize every dog is an individual but my males don't mark, roam, they are easy to train and they love me. But they are VERY location protective and my females weren't as much.
But despite all that, I'd go for temperment. I personally want a ball motivated dog who is people focused. Most breeders can help you select the puppy that would be best suited to your needs.
