Since I was a young child, I have had an enormous passion for horses. When I was eight years old my parents bought me my first horse; a three year old, untrained National Show horse named Maxx. Maxx was outstanding, and really took care of me; a kid that knew very little about the horse filld life I was bringing myself into.
Maxx's largest flaw was his club-foot, which caused muscle loss in his left shoulder from favoring it and made him off balanced in his back. At the prime age of eight years old, Maxx slipped in the pasture causing a transverse facture in his left front cannon bone. Ever since I have been bewitched with what makes horses move correctly.
Hoof Growth: Your horse's hooves grow about 1/4" per month. If they grow too long they'll crack, chip off, or break off in pieces and become imbalanced. That is why you need to have your barefoot horse trimmed about every six weeks. Even if your horse is shod, his hooves still grow, and they will grow faster at the toe than at the heel. So every six weeks or so, you need a farrier to remove the shoes, trim and balance the hooves, then replace the shoes. Shoes left on to long can cause irreversible problems.
