A miracle today:
Nick, the only animal at Howling Woods without wolf blood was so aggressive on arrival in December, most of us believed he would and should be put down for everyone's safety. The shelter's owner, Mike insisted he be given a chance, so we had no choice but to work with him.
As the one in charge of the socialization program, I know how to work with wolf-dogs who are more frightened than actively aggressive, but I didn't know how to deal with Nick.
I had to rely on instinct. I chatted to him (from outside the pen), praised him when he didn't lunge or snarl viciously at people, and got a father/daughter team to help take him for long walks with a "pack" (wearing elbow-high bite-gloves). He did better but still had issues when I took 2 months off to work at my spring job.
Today, I returned to the farm. I was admittedly a little nervous when he yelped and dragged the volunteer walking him over to me.
I sat down not wanting to look threatening. He seemed to remember our talks and walks and approached smiling, then rested his head in my lap, dog language for "I love and respect you."
I guess there is hope for Nick, but for many other dogs there is no chance.
btw... I would not recommend trying to rehabilitate an agressive dog without a ton of support and back up.
