Maybe you notice that the lower neck muscles of a horse you are considering buying seem very large or defined. Enlarged neck muscles can be a characteristic of horses that crib, an annoying and sometimes damaging stall vice. Cribbing and wind-sucking are associated with a higher incidence of at least one severe condition causing abdominal pain (colic). So you should make efforts to avoid purchase of a cribber. If you own, one then make reasonable efforts to reduce or stop these behaviors.

When wondering about muscle enlargement or muscle loss, always compare right to left sides for symmetry.
