She's plagiarized every play out of Katy's book except the chapter on being afraid of loud stuff.
I thought maybe we were going to have a problem with being afraid of loud noises when I got the vacuum out today. She reacted to it exactly like Katy does with all things large and novel. She skirted away, looking back at it with suspicion. To defeat that before it grows into a habit, I took immediate action and did a little 'counter conditioning' using systematic desensitization with her.
The point of systematic desensitization is to introduce gradually more scary things, waiting for signs of relaxation before adding more frightening stimuli. This is a recommended technique for treating phobias.
The systematic desensitization went like so:

After she expressed a keen interest in the cord I banged it against the plastic on the vacuum and rubbed it against the corrugated part of the hose. She didn't like that, but I got her to come back using praise and moving the cord around so she could bat it around. The next time, I did the same thing, but quieter.
Then I stood up and moved the vacuum as if I was vacuuming but didn't turn it on. She didn't like that and backed away. So I moved the vacuum backward and away from her and every time she moved forward, I moved the vacuum away from her to make it seem like she was chasing it off. Then I turned it on and continued to do the same thing. She chased it and then got bored and laid down.
Within minutes I was vacuuming right next to her nose.
So, using tried and true principles of behavior modification and learning, in ten minutes I turned a frightened little puppy into a calm one.
I'd love to use this technique with Katy to get her acclimated to strangers, but the number of people who are willing to play guinea pig with a huge, barking dog are vanishingly small. If I could scrounge up some brave volunteers, this plan from the Animal Human Society describes more or less what I'd do. I might have to run some counter conditioning on the volunteers to prep them for their roles, seeing as how they would be frightened of the big black dog!
In any case, given little Yuki's quick learning it will be interesting to see how many trials it takes to get her to learn commands like shake, lie down, back away and give. Katy showed herself to be a star pupil, learning shake in just four trials and the others equally quickly.
