It was dark in his stall so I couldn't see a lot, but I picked his feet out and palpated his rt front leg (the obvious problem leg). Nothing seemed too out of the ordinary, so I went home to grab a quick bite (and to grab the liniment) before returning to do a more thorough exam.
I pulled (literally) him out of his stall and into the barn lights. Picking up his hoof again, I could clearly see the problem: he somehow partially pulled his shoe earlier in the day. The shoe (which still had all 6 nails in the wall) was pulled about a half an inch back. He has front clips, so when he stepped down on the newly placed shoe the clip embedded into his hoof wall. It was in there about 1/2'-3/4'. It was about 7:30pm, so I wasn't sure if I'd be dealing with the farrier or vet at this point.
I called my farrier and he was awesome enough to come out free of charge and pull/reset the shoe. It did not bleed, and Monroe felt instant relief; he was 90% sound once the shoe was reset. We are on abscess watch, but since he didn't bleed my farrier is fairly confident he won't get one.
My farrier has never seen this, so he could really only speculate on what to expect. It makes me wonder, has anyone on here had this happen? He has been doing this for 30+ years, so for him to say he's never seen it surprised me.
It was a super scary night for me...Monroe is my baby (well, after my actual baby) and seeing him in pain killed me. I was ready to camp out in his stall all night holding his foot up.
