I have a neutered 4 year old German Shepherd, Labrador Retriever mix I have had him since he was 6weeks old about two years ago my house was broken in to and since then he has been very protective of me and the house he has bit 2 people that tried to pet him over the fence and drew blood . I have a three-year-old child that lives with us and the dog has to be muzzled when the child is home he has nipped him twice but did not draw blood. I just want my dog back to normal before I have too put him down because I know no one will take him. PLEASE HELP.
Over the years I’ve noticed that herding breeds crossed with retrieving breeds often have enhanced desire to protect territory that seems to kick in about 18 months of age and certain handling precautions are required such as no unsupervised time in yards or at window and ongoing clarity in the dog’s mind regarding its status regarding household relationships. The aggression towards your child is unlikely to be related to anything of a territorial nature. It could be some confusion as to household relationships or early socialization issues. I would have to know more before I could speculate or advise.
