There are 7 Youtube videos, about 60 minutes total. The presentation is put on by Trish King for the Marin Humane Society. Pretty decent. And she seems fond of pit bulls. Only weird thing she said is that pit bulls were bred to stare and make direct eye contact. I'd never heard that, but maybe it goes along with their pleasure in instigating fights?
This link takes you to where you can play all 7 videos.
