Thanks for all the responses, and I agree with all you have all said. Owner does care about the horse but plans to sell. She is starting him on bute today. Yes, the shoes could have masked the problem. Oh, and he is in a very dry pasture and is able to run into his stall which is 6 inches of sawdust on rubber mats. Which makes the thrush not make much sense because there really isnt any mud in his pasture. But, I suppose with shoes, he could have packed in some dirt and mud and it hung out there, Im just not sure. But now to add to it, although this horse will run through the pasture on his own just for fun he is sore. And holy rude!!! This boy has become rude to the point of dangerous. I watched him on a lead line last night, rear spin and buck like a fool! Just walking through the yard!! So is his discomfort making him rude? I don't know but he will start on bute today and the shoes have been off now for almost 2 days, I will be very interested to see what comes of all of this. Although I would love it if she would get some xrays on him, I so want to know whats going on. So, its possible xrays are coming soon. I have to wonder if he had navicular and maybe this last set of shoes just put him over the edge. Not that Im saying shoes are bad, Im saying that he is getting a normal shoeing and maybe that's not what he needed. I do know his old owner of 4 years was not so good about getting trims in a timely manner so maybe that has something to do with his issues today.
