If he's not flinchy about it and there's no heat in the foot/leg, I would probably take a wait and see approach. He might have stepped on a rock after the farrier visited and busted a vessel in there and bruised it. If that's what happened, then it's possible he could abscess.
He is barefoot and my farrier usually does a great job with no problems. This is the first time anything bad like this has happened making me wonder if it was his new assistant that did this. His last assistant he had cleaned the frog out with that scrapper thing while he did the rest. It makes sense that if the frog was cut short then he stepped on a rock he could of broke a blood vessel.
I do not have hoof testers but I did squeeze the heel, pushing in on it, and he did not flinch. I also did not feel any abnormal heat in the leg or hoof, no swelling in the leg either, which is a relief. So far we just dry bandaged it and are going to keep him on stall rest and see how it goes. Thanks for all the help!
