My mare is barefoot and has recently developed a large chip on the outside of her front left hoof near the heal. (I'll try to get a picture on Monday) It started as a small chip, half an inch or so, but now a bigger piece, about an inch or inch and a quarter long, has come off (moving toward the toe). The horse is not at all lame. Out of concern I called my trimmer and explained the situation. She told me that the chipping is a natural way of the hoof trimming itself and not to worry unless the mare becomes lame. The hoof is due to be trimmed in about 2 weeks.
Has anyone experienced this with your horse? Should I worry?
