Kelina, I can totally understand you I am a girl too and most of the time alone in not so good neighboorhood, when I walk my 7 month old GSD I am nervous and always wonder if my girl has what it takes, now I won't know for sure until something actually happens but here are a few situations that my dog was in that I thought she could be capable to protect me maybe not today since she is still a puppy but later im almost a 100% sure she would.
My brother in law hates animals him and my housband's cousing came over to our house, his cousin loves animals. My dog would not come up to be petted or to play with my brother in law even thoug she sees him almost every week. My dog has never seen my hubby's cousin but trusted him immideately and wanted to play with ball with him. You can interpet this however you prefer, im sure everyone on this forum has a different opinion but I think that my dog could sense that he doesn't like her.
My best friend hates animals she comes over once a week sometimes twice... They met when my dog was 2 months old and now she is 7 months old. My dog absolutely hates my friend, she will bark and try to nip at her until i tell her that its ok. It is kind of actually emberassing to admit that my dog hates my best friend.
My dog also hated my next door neighbor until about a month ago. She would not take treats form him or come close.
The other night my husband was by computer and he wanted to show me something and he ran up to me I was sitting close to the door to outside. The dog was sleeping right by my husband as soon as he started running the dog flipped out she started barking and growling and running to the door.After she saw there is no danger she went back to sleep.
Everytime somebody tries to get close to me or get a hug she comes over and gets her paws on me and tries to check it out
If I scream the dog immideately RUNS to me.
These are just a few examples, I notices she is more "protective" or whatever you want to call it of me than my husband. and very "protective" of my younger siblings who I don't even live with ages 5-11.
There are other little things that happen that I KNOW my dog can good sense about who that person is. Seems like my dog just loves kids and loves people who love her.
As far as protecting me I can only hope that she does. I can see that while she is maturing she is becoming more confident and doesn't run away from "scary" things she comes FORWARD. If I were you I would carry pepper spray with me and a knife or a tazer. You never know what can happen.. your dog may protect you from one bad guy but there could be a whole gang following you and your dog won't stop them, If you scared to walk outside definetely get your dog into protection training it will make you feel safer but nothing is a 100% even if you had a gun on you. A dog is a good detterent though.
Another thing I will add is that it is ridiculous to hear some people here say "I would want to protect my dog instead of the other way around" People comepletely turned a GSD into a house pet. GSD is a protector that is their job the only time they woudln't protect is when they don't have a good bond with you, dogs always fight for their pack. But to be honest I wouldn't over socialize the dog so she doesn't just jump into everyone's hand to be petted.The dog may not protect you while still a puppy but when he or she is mature I am pretty sure they will. Its in their blood.
