Over protective of owner
My mail GSD is a little over 1 year old. He has been a very well behaved dog and I can take him everywhere and usally do. I take him to the hardware store and all the girls fawn over him and give him treats. We go to our local Dog park and he is fine with other dogs, he will romp and play with them and is not agressive in any way. If two other dogs go after each other, he just stands and watches.
My problem is he is over protective of me, in that if I try to interact with another dog he will jump between me and the other dog. I can bend over and start petting another dog and he will see it from the other side of the park and come running. He used to just jump between me and the other dog, and if I stop paying attention to the other dog he goes back to normal. I don't want this to escalate into a bigger problem and I love interacting with other peoples dogs, which I can't do right now. I have never seen him get aggressive with another dog unless I am involved.
I don't have any friends with will behaved dogs that I can get with to work with him in a smaller controled environment. Anyone have any suggestions?
