Fair enough! Like I said, I posted in case anything jumped out at OP. I agree that every owner should do what they think is best. If their horses have crappy feet, it’s time to really study the management instead of blame it on the breed.
I need to go find it but there’s a study out there that showed (on average) horses’ hooves begin to distort at 3 weeks post trim. I know this is true for mine - 5 weeks is often WAY too long and they’re taking a ton of foot. If the horse isn’t growing enough foot to trim at 4 weeks (especially shod), I’d start looking at diet, trim, and workload (is the horse just wearing off their foot).
Hoof boots can be miracle workers, but they take some commitment and dedication!
