I think you've gotten some very good advice here - my recommendation is to get a new farrier immediately. If you post on horseshoes.com, I'm sure you'll be able to find a qualified farrier in your area. Or I would imagine your feedstore or vet has someone they can recommend. Definitely change who you are using - this is not a farrier!
