There probably isn't a good answer to this, but I thought I'd run it up the flagpole anyway ...
I live in a seedy neighborhood with major drug problems. It's what got me interested in MA. I'm a real homebody with a telecommuting job, which means that most of the time I'm out and about, it's because I'm walking my dog.
He's a 7 and a half year old border collie-chow mix, about 65 pounds of gorgeous fluff. He has a little arthritis. And he's a medical service dog dropout (read: impeccable manners and temperament) who didn't make the cut because he's too vocal. Among those who don't understand dogs, his barking has given him a vicious reputation.
Stop and offer him a hand, and that barking gives way after a couple minutes to undying love ... you know how dogs are.
I have no illusions about him coming to my defense in an attack. That was tested once and he barked ferociously from behind
me. I wonder about his safety in a SD situation. Border collies were bred to manage sheep, which means that they respond to any flurry of motion by frantic circling, barking, and nipping. That nip could be helpful, but I'm more worried about him getting trampled by coming too close. All of which is complicated by the fact that I use an over-the-shoulder leash, so I can't just drop the leash and fight without a moment's grabbing and bending over to twist out of it. We're physically stuck with each other.
Is there any behavior I could teach him to offer a more convincing bluff? Or maybe some MA system or moves that wouldn't involve my doing so much jumping or twisting that would jeopardize him?
I offer gratitude and milk bones in advance ...
