i've never heard of it but its actualy kinda cute ^.^ (not that i would ever want a horse like that though)
They would let a deaf horse run. Some wear ear plugs that block almost all sound as a way to keep them calmer. There is a Standardbred stallion(Oaklea Julian) that raced most of his career with only one eye. He had a great career.I would guess that it was either some kind of genetic deformity or a birth defect. It is also possible that it was an injury suffered as a foal. I can't really see them letting a deaf horse run but IDK, they might.
these are the same thing.either some kind of genetic deformity or a birth defect.
