> It requires you to act like the alpha dog (which is a very awkward feeling to most people) in order to maintain the behaviors you want.
The "alpha-dog" theory has been totally disproved by dog behaviourists. It was an extrapolation from a single case study in the 1930s, of captive wolves. It has since been debunked, and is not even applicable to wolves, never mind domestic dogs.
All the dog training which is based on this (such as Cesar Milan's submission-based training) holds no merit, and is far more likely to be detrimental than positive, as it relies on terrifying the dog. Note that this was only debunked in 2000, so a huge amount of dog training and research needs to be revised as a result.
