A wonderful example of a dog telling us what she wants and needs
I'm a fan of positive dog training, valuable lessons that I prefer to call dog teaching. While I'm not a dog teacher, I talk with many people around the world who work with a wide variety of dogs displaying various behavior problems, and across the board they agree that positive training is the way to go for getting the best, most consistent, and long-term results.
I recently received a video of Holly, a dog, being hit - cuffed in the neck - by, and later biting, Cesar Millan. I had not seen it before. In this video, Mr. Millan moves closer to Holly while she's eating. Holly eats faster as he moves in and immediately moves away as he continues to approach her. Holly gives him plenty of warnings -- don't come any closer -- because she needs her space to feel safe. Mr. Millan ignores these warnings then cuffs her in the soft part of her neck; you can see this at 0:44 of the video.
After talking briefly with Holly's human companion, and with Holly appearing to be relaxed but still stressed, Mr. Millan swipes at her face and Holly then snaps at and bites him on the hand, drawing blood; you can see this at 3:44 of the video. Mr. Millan admits he "didn't see that coming." He goes on to back her into a corner.
