Back in the day before automobiles, a good horse trainer and veterinarian was the equivalent of “Mr Goodwrench”. A badly behaving or unhealthy equine was equivalent to breaking down on the highway or running out of gas on a lonely stretch of highway somewhere in Utah. My sources tell me that most of the training methods are ok, but stay away from the medical tips unless you are prepared to become the poster boy or girl for the local SPCA. Listen with tongue in cheek, and check with a professional before attempting any of these techniques on a real animal.
