We happened to watch an episode of the “Dog Whisperer” on cable TV (National Geographic channel) in a hotel room while we were traveling and speaking, and found the work Cesar Millan does with the dogs is much like what we encourage people to do with their livestock. He teaches people to understand their dogs and deal with them in a positive and assertive way.
Check out the show or read his book, “Cesar’s Way.” We found much of it applicable to other livestock (and even children!).
