I noticed it yesterday morning. Then farrier confirmed my suspicions today. He advised box rest and hoseing down. Which I’ve done. I’ve left him in today. With leg wraps on. I’ll see what it’s like later x
It really depends on how long it's been going on for. I would give the horse a day or two and see if it goes way, because it might have just been a bump, but if it doesn't go away then take the horse to the vet.
