Not to sound like a total fruit cake, but I think if you "listen" to your horse, they tell you what they want or need. For instance, before the abscess blew, I knew something was up, and now after we have discovered what it is, if Oz wants his foot soaked longer, you are not moving his foot from that bucket until he is ready.
Also of recent talk around the barn is the topic of farriers. How do you know who's good and who's bad? What's too much to charge? And then when you encounter a problem, is your gut right about it or are you really the idiot that just knows nothing about feet? It's such a touchy situation, with the clients and farriers both alike. I guess to each their own and obviously if there was only one right way, then there wouldn't be all of these different farriers and techniques out there....
