Needless to say, my new farrier trims the frog every time and those horse's feet haven't ever looked better, and he hasn't been this sound in a long time. But, to each his own--when it comes to hooves, no two things work the same on a different horse.
I don't believe a frog should be trimmed routinely at all. I will remove flaps & tags, but not always. Depends on the climate & what they live on too. If the feet are likely to get & stay muddy, I will remove flaps that could harbour thrush.
Routine trimming of frogs not only removes the calloused(hopefully) outer skin & makes the frog more sensitive, but in exposing the softer material actually further encourages thrush. I suggest there has been more going on than just whether the frogs are pared or not, if the horse no longer has thrush. The method of trimming - principles that are followed - has a large bearing, as do diet & nutrition, as do the environment the horse lives on & his lifestyle.
