I snagged these photos from an online barefoot trimming group. It was recommended to the owner a few months ago to stop trimming the horse (he had been sore after a trim) and just to let the hooves grow. Here they are a few months later. What do you think? Chalk this up as another win for the "celery" approach?
(You'll see some pictures where the hooves have been touched with a rasp- we'll just ignore that for now.)
