Bad Timing

Dont horses have the worst timing ever? Do they know when something big is coming up? Well I had been riding vodka mainly hunter recently to get ready for his first hunter show that was two weeks ago(he did great). But the next thing on our plate is to go to a USDF show we leave on friday. Last Wedsday was going to be his first time back in the dressage saddle his shoe was a little loose not much at all so I was going to do a light ride in the indoor with him but he was lame like head bobbing lame. So I gave him half a gram of bute bc i thought it had to me something with the shoe. I just wanted him to be comfortable until the farrier could come out. The next day i went out to check on him and he ripped off like half of his off wall. I called the farrier and he said dont pull the shoe just duck tape it so i did and he was lame poor thing. So now his hoof is patched and he is almost sound. I was riding on friday and he decided so learn how to buck its just perfect just perfect i guess it is just...bad timing...
