you watch these shows and videos.but ask yourself,did I watch this horse grow up and did I see how many times this was tried before going on film?
That's very true, but a lot of his tips and tricks can work on other horses as well, not just the ones he's working with at the moment. Just like any trainer, you take what you like with a grain of salt, leave what you don't like, and use what works best for your horse and you. No one is saying use only Clinton Anderson's methods and you have to think he's some sort of horse training god.
I, for one, have used a lot of his techniques on my two-year-old and he's a better horse for it. My friend uses a lot of his techniques, as well, and finds they work for her. Do all his techniques work all the time? Nope. But it's always fun to watch him work and think about things you can do with your horse.
