Since Farrier is due next week, I would put a new plan into effect, talk to the Farrier BEFORE he does anything with the horse.
I would want NO SOLE trimmed off this visit. I would not want him trimmed SHORT on the wall either, just enough to level things up. This should fall within the short working window of time horse allows hoof work done. NO CORRECTIVE trimming done, no matter what the Farrier says about turning horse toes in or out.
Take some photos of hoof sole, before and after the trim. Some from the side, before and after the trim of each hoof. I might be obnoxious enough to measure each side of hoof wall, inside and out of EACH hoof, to insure they are equal lengths. Toe length should match on each pair of feet, though fronts may not be the same length as hind hooves. That is OK. Write it down as your starting point, before the trim in horse records. Then measure again after the trim, again both sides of wall on both hoof pairs, toe lengths should be equal on each pair. If not have the Farrier do a little rasping to equal the sides on a hoof, with each pair of hooves matching the other hoof in wall and toe length measurements. Don’t let him rasp anything really short to match the other side of hoof! You are looking for balanced hooves of equal sizes, wall heights, toe lengths when the job is finished. This is ALL presuming your horse has no problems, a dished or upright hoof, non-matching pairs of hooves that have to be dealt with.
You stand right there, watch and remind Farrier NOT to take off sole, nor trim walls really short if you see the hoof knife or nippers in use. This time of year is when horse hoof grows the least, you can’t afford to lose any more hoof and sore horse up. We have horses the Farrier may just run a rasp over, smooth them up, take any nicks out, because they are not growing hoof now. Yes I pay the same as when horse is growing hoof, for the trim. I am paying Farrier for his time and expertise, keeping horse usable.
I would be rather shocked if any of our horses limped or needed ‘rest time’ after a trim to recover. That is totally unacceptable. Doesn’t happen here, Farrier knows what to remove and WHAT TO LEAVE ON when trimming or shoeing, horse is immediately able to be ridden and used, even very hard if that is on his conditioning schedule. Horse does NOT get sore after shoeing, trimming or use starting 10 minutes after Farrier put the last hoof down.
Then when your Farrier is done, jog out the horse, see if he still limps. I am thinking he should not, with no sole removal or very little to no wall shortening. Sometimes just a polish of hoof wall with the rasp is all horse hoof needs. You GOT your money’s worth, horse is not lame. Farrier doesn’t always need to leave those trimmed hoof rings to show “Farrier did his job”. Or at least I hope not.
Hope to hear better news after the planned visit by Farrier next week.
