Quarter cracks are vertical cracks in the hairline or coronary band of the horses hoof. They can be large or small, they can bleed and they can make a horse lame. Since the crack is sometimes an open sore its best treated in some way. Depending on the causes of the cracks they don’t all heal by themselves unless something specific is done.

The problem with dealing with quarter cracks is the movement and stresses put on the foot that spread the crack and prevent it from mending. If the horse becomes lame the problem usually can’t be ignored.
