I haven't done any clicker training myself (haven't done much training in fact, haha) but I am all for anything which uses positive reinforcement really, if it's effective. I was thinking about this lately as I have been flushing out my horse's mouth after a tooth extraction... I thought I had no chance at all and it was very difficult to start, but I really worked hard on my patience and keeping it positive and I think we've done an OK job. I mentioned it on Facebook in the beginning (just posted a funny photo of her looking unimpressed) and someone, albeit abroad, immediately suggested an ear twitch to get the job done! Really made me stop and think about the different trains of thought.
