[London's Mom]

I have been experiencing the same problem with London now that he is 90 lbs and 20 months old. It is all I can do to hold him back. When I see another dog approaching, I pull him into a driveway, make him "sit/stay" and stand directly in front of him so he is forced to focus on me. I have been having more and more difficulty with him.

It is SO frustrating because I still have been taking him to Intermediate Dog Obedience once a week. He is perfect in class: knows and performs all commands, plays with the other dogs at the end of class, allows other people to approach him and pet him.

My trainer said that it was a territorial thing going on with him here around our 'hood. Geez, I wish he would chill out. It does help to have him on his gentle leader only because it is the only way I can constrain him when he gets in a frenzy.

My last male GSD was the same way and he NEVER got over this behavior. With London, I have been trying SO hard to make him a "neighborly" GSD. Is it possible, or am I fooling myself????
