I just brought a new 5 1/2 month old female German Shepard home yesterday. I have at home a 7 1/2 yr old Golden and a 7 yr or so old Yorkie Mix that are both males. The dogs get along right up until I am petting my new dog and one of the other ones come up and I start to pet him too. She gets mad and barks aggresively toward them and chases them back to get them to back away. She hasn't bit them yet, but I am affraid that is where it will go. She has also done this another time over a toy. My daughter was playing with a rope toy with the Golden and she went over and was going to play too and I thought GREAT maybe they will play together tug of war... She had the toy and as soon as my golden went to get it again she went after him. I have told my daughter what the breeder said to do was to grab her collar (which is similair to a pinch collar) and pull back and say NO, or grab her muzzle and again say NO. Well when she went to get her collar, it may have startled her and she turned around and went to bite my daughter. She didn't hurt her but but the way her tooth hit my daughters skin, it broke a blood vessel. I IMMEDIATLY got ahold of her muzzle and told her NO.
They (the dogs) are fine in the same room and everything till one of the 2 above scenarios.. ANY IDEAS of things I can do???
Also a little background on her parents. Her dam and Sire are both mulitple titled with Shuzthund (Schh3) and KKL1 and PPD and other things. My goal is to get her started on training in Shutzhund for starters.
I'm not a profesional dog trainer, but I wonder what would happen if you gave her a time out in another room or an outside run for awhile every time she misbehaves. She is at a very "bratty teenager" stage right now and needs alot of direction to feel secure.
Thanks for your response. She is actually doing GREAT now. I think she just needed a few days of adjusting. She gets along great now with the other 2. As a matter of fact she plays alot with my Golden and she also rolls over to her back to show her submissiveness.
Your dog regardless of breed sounds like a very nervous dog. I would also bet money that she bit both you and your daughter out of fear. If you reach, grab or advance to fast towards a nervous/fearful dog you risk a "fear bite". Fear bites are the most common reason people are bitten by dogs. I know your thinking how can she fear us we love her, but in that moment she felt threatened and you just didn't get the memo she was sending.
