This would be my game plan. Make an appt with the vet for x-rays and Previcox. Get a farrier refferal from the vet. Farrier's working through vets are thorough and will not cut corners. If the horse is in pain, she may not be such a wonderful horse for the farrier to shoe. It may be too time consuming if he has 30 more head to trim and shoe by the end of the day. I have seen farriers pass due to time restraints, and this is a busy time of year for them. First this thread blamed a crappy farrier, and then blamed the owner for not making said crappy farrier do his job. All of this finger pointing is useless in helping OP help this horse which does not even belong to her.
