Hi, I bought my first horse 2 yrs ago. A 16 yr old TWH gelding. A yr later, my vet told me he was more likely 25-30, looking at his teeth. (this is still debatable). In March last year he had foundered. We had shoes put on his front feet. He's been doing better all along. 2 weeks ago I asked the farrier if we could take his shoes off for the remainder of the winter. It's very snowy here and his shoes just seem to accumulate ice packs. The farrier said that would be fine. The next day, the horse started favoring the right foot (always the problem foot). I thought maybe just because he was trimmed. Over the next few days I noticed more bruising on his sole on that foot. Today he has a piece of the outer hoof chipped away. He's outside 24/7 with his stall open to the paddock and a run in shed as well. I don't know if this chipping is normal when the shoes are removed? It's pretty big, like an inch long and 1/4 inch thick (or deep). I'm calling my farrier to ask his advice, but I wanted to run this by you all as well. Tonight he'll start getting bute in applesauce...he hasn't needed since spring. I don't know what else to do for him.
