Ok I realize I am chiming in on this very lengthy post, and I also admit after reading all of page 1 and several posts on every other page, I must say... that I totally concur with Eileens first page post >totally<...and I would like to add my own thoughts.
There are sooo many training methods, there are soooo many "dog personalities", NO ONE method is right for all dogs. My father used to say:
You can please all of the people some of the time, Some of the people all of the time, BUT, you can NEVER please all of the people ALL of the time!

That being said... the same would hold true with training methods! Right? Well I have been training dogs for over 20 years, some through dog training clubs with my dogs, some methods I've learned through reading, some through training classes/seminars/workshops/videos etc. and finally professional certification as a Pet Trainer. As of now, I own and manage my own Dog Training and Behavior Consulting business. Over the last couple of years, I have used exclusively Positive Feedback/Reward Based Training. However and a really big HOWEVER!... along came Phoenix. My very precious Border Collie boy (not my first BC). As far as obedience training..he excelled, no suprise there. He went to work with me, met all sorts of strangers (and some actually and literally strange LOL!), kids, other dogs, cats etc.) He was maturing into a very nice social doggy. Then one very cold winter day, ice covered my windshield, and I decided to let the heater melt the ice off. So Phoenix and I were sitting there side by side, when after I started my vehicle, I accidently hit the wiper blades. B A M!!!

there went Phoenix, after expressing his anal glands! Peeeee-UUUU! over the seats to as far back into my Nissan XTerra, that he could get, and NOTHING, was gonna get him back up front.
Well that was the end of him getting in the car by himself, he would run out the doggy door and hide behind a bush in the back yard, if he even thought I might want to take him somewhere. To make a loooonger story short, on advice of a Behaviorist, I use my positive training to get him over his fear. 3 months later... finally he jumped into the car. Ok, sounds good up til now. During that 3 months of not going anywhere in the car (also behaviorist advice), he now developed a serious aggression toward people, other dogs and kids!!!! Now what! I was sooo upset, we cured one problem only to create another even worse. I tried again for many, many months to work with this aggression, all the positive stuff I knew. Not working... period, and it was getting to a point that it was only a matter of time before he bit someone. I decided to weigh all the good advice I got on these boards, and eventually decided on starting herding training with him. I was told that the discipline methods used with seriously whacky dogs may be against my current training methods, so I had best be prepared. Well anyone here who was at that first Herding Clinic I went to with Phoenix last June knows exactly what I mean! The first 5 minutes we were there he showed his attitude, got whacked on the butt twice with a stock stick and told in no uncertain terms, you will not do that...! We have been doing our herding training for a year now, and let me tell you up until this past March's clinic, Phoenix got in trouble every time, but it was less and less everytime we went. The aggression and whacky attitude toward people was the first to go, and now he can actually pass a dog nose to nose, and nothing!
Soooooo, my point is all the positive training in the world was not going to stop Phoenix...BEFORE... he bit someone. I never would have used physical discipline on him, but that is what it took for him. He is really maturing into a very nice dog now. We still have very minor incidents now and then, but I have people coming up to me now who saw him last June, and they are amazed at his changed attitude.
I now train with a mixture of methods, and personalize my training depending on the dog and the people involved (the people being the biggest problems by far!).
Excercise, discipline, then affection (Ceasar) Rules, Boundaries and Limitations (Ceasar) what's not positive about that?!
I think it's unfair for anyone to say he has been deliberately cruel or killed dogs? Please he is only 1 trainer, and I know he has made a positive difference in many dogs and peoples lives. No one is perfect, no one. No one method is perfect!
Like has been already said here, if you don't like it don't do it... seems simple enough to me.

I happen to be one that likes Ceaser. I don't agree with everything he says or does, but I do agree and use many of his methods...depends on the circumstances and the people involved.
