I wouldn't presume to specify that she needs "one inch" off; that is a LOT,on such a small animal...but I certainly agree that her feet are much too long, and need a uniform trim(meaning not just of the toe or just of the heel, but 'all around'.) It may not be possible/safe to take off ALL the excess length in one trimming, because the 'quick' tends to advance downward in a hoof that has gotten too long, and may need to be 'driven back up' by repeated moderate trims, usually closer together in time than the 'usual' interval of 6-10 weeks.
I also very much agree--you need a farrier who actually knows what he/she is doing! Lack of genuine ability may be why your current one gets so much less than others for his work!
