Thanks to my excellent trainer (HMT), protection work taught me a lot about my dog. By channeling Brockle's aggression, I was able to gain control of it. By gaining control I was able to discover how much he didn't want to bite. Brockle doesn't want to bite anyone, or anything for that matter.
If he felt danger approaching he would become anxious. At least he did if I was on the other end of the leash, he was perfectly willing to let the HMT be eaten by the bad guy (decoy). He would offer every kind of delay tactic he could think of, while becoming more and more agitated. Finally he'd explode and go after the decoy with everything he had.
Brockle will go down in history as the dirtiest biter the HMT ever came across. This is not a good thing. Dirty biters refuse to honor the protective sleeve they are trained to grab.
He was never rushed. We were several months into obedience, playing tug and encouraging prey drive before he went to defense. Still, the first time he actively defended me, something triggered and he began to try to bite in earnest.
Brockle would knock the sleeve aside and go for the throat, belly, thigh or groin. He would slither up under it and go for the face. It got to where he wouldn't play with the sleeve anymore. He was becoming wary of our decoys, even his best friends. Brockle didn't see protection work as an amped up tug-of-war like the other dogs. He saw people he trusted acting in a threatening manner. My dog was not amused. In his defense, he always listened to my "Leave it!" and faded off, it seemed like he was relieved.
We decided to back off and just play ball on our weekly workouts.
My good friend, Batman, was always one of Brockle's favorites too. He worked on our place most week-ends and the two of them put in a lot of ball time. He was also a kick ass decoy - the last one willing to work my dog.
Batman offered to play with Brockle. After all, he wasn't geared up, what could go wrong?
He threw the ball out in the field, and my dog bounced after it, his tail a flag wagging in the wind. He scooped up the ball, Batman called, "Good boy!" and clapped his hands. Brockle bounced over, all happy and cute, until he was maybe a yard from our friend, spit the ball out and leaped for his groin. He caught his jeans, but not any skin. Like I said, dirty biter.
That was the day we ended protection training.
We still went to training, but now it was to bring him down. To make friends with the people he felt had crossed the line. A lot of ball, a lot of obedience work and tons of ball slowly brought him back.
As the summer progressed we did the same at home with the crew working on my barn. Batman was there to keep an eye on things and I figured out his triggers. By fall, Brockle was almost back to normal. His recall was about perfect, I could put him on and call him off and he was reliably friendly with the people coming in and out of our place.
He will nip the goats when I tell him to "Put em'up!" He will air snap at a horse trying to slip out a gate and he still fights with my rat terrier Charlie. That, of course, is still Charlie's fault. He'll chase down a rabbit, roll it and let it go, just like he used to do in the dog park. Like the many dogs he rolled, the rabbits don't appreciate him-even if he doesn't want to bite.
