Definition: A horse that stands with its hooves wide when viewed from the front, then narrows as the legs attach to the chest is said to be base wide. The horse is often narrow through the chest. Because the weight of the horse is carried on the inside of the hooves, they may be more predisposed to unsoundness.
Pronunciation: b ā s w ī d
Examples:
When a horse is base wide, extra stress is put on the inside of the hoof causing extra stress on the fetlocks and pasterns that lead to arthritis.
