Did your farrier show you how to do any rasping yourself? If there’s any way for you to take a few swipes of the heels, refresh the rolling of the outer wall, you can likely make faster progress than even trimming every 3 weeks. Crushed heels easily continue to follow that growth angle, so if there’s a way to swipe them even twice a week, you will likely make faster progress.
So much depends on the skill of the farrier, frequency of trimming (see above) and how comfortable the feet are. The more the horse moves, the better the growth rate, which means more of the old “wrong” foot can be trimmed each time. Going 3 weeks will make faster progress than 4+, so that’s a definite plus.
If the diet isn’t supportive of optimal growth, I’d address that. What’s he eating?
It depends on how unhealthy the feet were to start. The less healthy, the most likely you’ll run into an abscess here and there, or at least some bruising. I WOULD have boots on hand just in case, as you don’t want a sudden dry spell making really hard ground and getting him sore to the point he’s not using himself well, which can then start causing body issues.
this speaks volumes about the progress so far, and the basic health of the feet to begin with.
I am very pro-barefoot, but not at all anti-shoe. More horses CAN be barefoot than owners are willing to do, because some don’t want to deal with boots, ever, even though some boots are so safe and secure and easy to use for many situations. But not all disciplines allow boots, so sometimes that’s a driver
In this area, owners need to become as educated as they can on what healthy feet look like, because unfortunately, there are a WHOLE lot of incompetent hoof care “professionals” (HPCs). They can talk a good talk, or at least sound like they know what they’re doing, but can’t (or won’t) trim properly. In this area (any area really) it’s always good to learn as much as you can yourself, so at least you can have more intelligent conversations to try to see when they’re BSing you.
Yes and no
Yes, in that you should most definitely see improvements in his level of comfort. It may not be a straight line, there are some adjustments, but the general trend should definitely be upwards. Feet grow at roughly 1/4" a month, and most front feet are grown out in 9-12 months, hinds a little shorter (they tend to grow faster). So in that 6-12 month range you can still have old hoof wall starting to hit the ground, and if it’s not quality wall, still see some cracks and breaks especially towards the end of a cycle. But he shouldn’t be more sore, or even AS sore as he was in the beginning, by 6 months, not by a long shot. It should be clearly evident by 6 months that things are improving
One caveat is that most of the next 6 months are Summer ,and depending on where you are, is a land of hard ground and flies. For this reason, it’s more optimal to pull shoes in the Fall, going into (usually) a rainy season with softer ground, well ahead of Winter frozen ground. It’s your specific location that matters most, so just know if the ground suddenly gets hard, and he seems a bit sore, more boot time, or put shoes in for 1-2 cycles to get past that, or otherwise help him out, just don’t assume barefoot in general isn’t working for him.
