I got to the barn today and my BO had trimmed my horse's hooves for me- this is the second time he's done this. He's not requesting any payment for having it done, but I don't want him doing it. Last time I hinted that I'd rather have my regular farrier do the trimming, but he didn't seem to get it, I guess.
The worst part? He trimmed so short that my gelding won't walk on pavement. :S
How can I let my BO know, nicely, not to trim my horse's hooves without asking?
(To clarify, my horse was not overdue, I keep a close eye on it.)
