We have a sweet 15 week old gsd who is a really sweet boy. We live in a secluded area on about 40 acres and have bears, wolves and and some coyotes. He sleeps by my side of the bed at night and if he hears anything outsidehe gets up in the pitch dark and patrols around our house from room to room and just once in a while a little growl comes out. We have been socializing him to the max and he loves everyone and very social.Just hoping he is not going to be aggressive as he gets older, or is this just their instinct to protect us when he is just so little???????Thanks in advance.
