Cesar Millan uses traditional, old-school punishment and aversive methods to train dogs, that the American Veterinary Society has their own position statement on:

/position_statements/Combined_Punishment_Statements.pdf 

"AVSAB’s position is that punishment
 (e.g. choke chains, pinch collars, and electronic 
collars) should not be used as a first-line or 
early-use treatment for behavior problems. This 
is due to the potential adverse effects which 
include but are not limited to: inhibition of 
learning, increased fear-related and aggressive 
behaviors, and injury to animals and people 
interacting with animals."


In Cesar's shows, there are some episodes where I have seen him use positive reinforcement training but it is rare. Usually he chokes the dog with their collars to 'calm' them or let them know who's boss, or he kicks them in the ribs to change their mindset.  Aversively training any animal results in loss of trust, fear, avoidance behaviors, aggressive responses, and can even make the behavior worse (depending - some dogs may think they are receiving attention for a bad behavior, or they can even become less pain sensitive). here's a study that's more scientific 
[http://binalunzer.com/Links_files/aversivestimulation.pdf ]. Training like this on TV makes the general public think that it is OK to do this form of training even if animal is in pain, and families routinely try to 'alpha roll' dogs at home resulting in dangerous confrontations. Oftentimes a family trying to mimic Cesar's training gets in trouble.  Don't forget children are watching the show, too. 

Positive training can train dogs just as well as punishment training most times. So, why should we use shock collars, kick dogs, and choke dogs? Positive training is safer, effective, and family-friendly.  If you do your own on-line search, you will see the wide array of opinions on Cesar - for example see this New York Times article [ http://www.nytimes.com/2006/08/31/opinion/31derr.html?pagewanted=all&_r=0 
]. I have seen Cesar use an electric shock collar on the show and not tell the audience, and I have seen dogs pee themselves out of fear on the show as well. He never addresses what's going on at those times; [ http://www.youtube.com/watch?v=Qh9YOyM2TAk ]

There's no arguing that punishment training can work (it has for 75 years), but if there are better methods out there that are just as effective and scientifically proven to be better, we should use them, in my opinion. 

Don't you want your dog to look happy when they train?

As Cesar Millan completes his SIXTH season in media, he has come to be known as a household name. In 2006, the New York Times wrote an article named 'Pack of Lies' where they explore the real training tactics that The Dog Whisperer uses. Read the article and see for yourself. I myself train differently and have to allow for freedom of speech. But take note, since 2006 The New York Times has written other articles noting the PRODUCTS that Cesar Milan markets, and how families are starting to train their children as he trains dogs.

Dominance theory, pack theory, and the forms of training Cesar uses are all another way of saying AVERSIVE training. It is a very traditional technique that is starting to lose hold in the training world for many reasons. 1) It's dangerous to try at home without a trainer 2) Dogs can aggress back 3) Dogs will find other outlets for their aggression 4) Dogs will find other people to dominate if the REAL problem isn't solved 5) It causes a loss of trust in the relationship 6) It stresses the dog, and can cause real damage and pain (I've seen this occur) 7) It doesn't work on all dogs (even though Millan's series shows the dogs it does work on - READ THE NOTE the author Shibashake makes herself after she weighs the pros and cons in the article below, 'Aversive Training Pros and Cons').

Keep in mind that many many trainers train the Cesar Millan way to this day with all types of animals - horses, monkeys, show/agility dogs, anything with a leash or lead. I have personally been taught by trainers of this mindset as well. I have as a student and trainer taken an OATH that I will not train aversively if it is avoidable. But if it seems that this is the only option I must make every effort I can to solve a problem.

I have included some articles from the NYT on Cesar Millan, and one from a page detailing some pros and cons of this form of training. Weigh it out yourself, everyone!
