Aggressive dog training? Caesar Milan?

A friend of mine and I were talking about dogs, she was telling me that her 2 year old Shiba Inu that she just adopted a couple weeks ago is showing signs of aggression to certain family members, strangers, and other dogs. She always brings up "Ceaser Milan" and his show the Dog Whisperer, she bases her dog training on his show. I personally don't believe his methods of training are correct, in a lot of the shows he condones using "dominant" methods over the dog, which sometimes can be a bit harsh. I don't believe these methods are right, i think they just provoke fear in the dogs. Dogs know we are not dogs, they look at us (the owners) with love and loyalty, by us trying to prove our dominance to them i believe it just provokes fear, and while that may work in certain situations, that is just making the dog afraid of you. Anyways I told her this and every once in a while, she will tell me that i do a bad job at training my dog. Just because i choose to use different methods other than dominance doesn't mean my methods are "wrong". I even let her walk my dog once and she explained that if you hold the dog on a very short leash and keep pulling her back harshly every time she tries to go ahead of you, she will eventually learn to walk right next to you. I felt so bad for my dog, she was practically getting whiplash, and her method didn't work at all :( What do you guys think of ceaser milan and his "dominance" technique in training? I personally believe that show is outdated and he is not a real educated trainer, she should not base her training on a show on TV. She should get some real one on one dog training with a licensed dog trainer. Am i right?
