That is quite a range: from $21,153 (part timers) to $200,000 (farriers who work on race horses and show horses). In between that is $40,000 for farriers who work mainly on pleasure horses. Am I correct in assuming you think he is on the higher end close to $200,000? Can I ask why you think that he would be?
I would put PF in the lower range in my opinion based on the clients I have seen speak to the press about him. He works on the donkeys for the 2 Mile High Club in Cripple Creek which is a non-profit group and may not pay as high as other clients. We're not allowed to sleuth the individuals who spoke and said PF did farrier work for them but my impression from their interviews only is they are neighbors or former neighbors and more in the "owns one or two pleasure horses" category than the "wealthy hobby horse in show/race track" category. And that link also assumes salary for a "good farrier". We don't know that PF was a good farrier-- we only know some said they were not happy with his treatment of their animals and one said she stopped hiring him. That kind of reputation, if true, would be bad for PF's business prospects. PF might have earned more income from his dog breeding, cattle sales and rodeo competing. But it's really anyone's guess how much he made annually. MOO.
