I see. In my experience, (admittedly limited compared to his) in actually going into people’s homes, what I generally found was a dog without any *real* problems, but owners who just didn’t have a clue about basic dog behavior. They were treating the dog like a kid. But, it was frustrating to try to get them to do what was required. The dogs were fine with me, would learn behaviors quickly (sit for instance) but the human often didn’t really WANT to be the boss.
Dogs are dogs, not people and when people think otherwise, I think it’s generally to the dog’s detriment.
But, I have seen a few dogs (when I worked for a vet) who I think should have been euthanized for safety sake. They may have been ok in very specific homes, but they would not ever be suitable for the normal dog owner.
Just my opinion, I have not really kept up with the newer training methods since I only train my own dogs now, and what I do works for me.
I looked around a few minutes, and there's actually a lot of Cesar clips on youtube, if you can watch those. They're shortened clips, of course, but they help get a feel for the guy... I haven't found the one, quintessential clip, you should watch several.
This one isn't bad, but it underplays the walking part probably. When you watch the show, the walking part is important for getting to the right state of mind.
