We do our own trimming for the most part, but I have our farrier put pads and shoes on and off depending on who is going to show and who is training....
His price varies per horse depending on whats to be done.
Usually spending $85. Per hoof, that's including shoe,pad,putty and fitting.
It costs me $65 per trim (and that's cheap in my area)...$175 for plain toe clipped shoes...and I don't even want to know what padded or special shoes would cost....I'm sure it would be well in the $200 range.
I've only shoed my mare once since owning her. However, I do plan to shoe her again this coming spring. They're needed when I drive her on the roads. Her shoes weigh a ton!!! Luckily, I do have a good draft horse farrier who knows what he's doing.
