Stable design profoundly affects horse welfare. Horses evolved as social, wide-ranging grazers, and housing systems that restrict movement or social contact can cause significant physical and psychological harm.
Traditional individual box stabling, while convenient for management, is poorly aligned with equine behavioral needs. Horses are highly social animals with strong motivation to move, forage, and interact with others. Confinement in small, isolated stalls for extended periods drives high rates of stereotypic behavior and may contribute to gastric ulcers, respiratory disease, and musculoskeletal problems. Modern welfare-oriented stable design incorporates larger stalls, windows between horses, group housing, track systems that encourage movement, and structured turnout programs. The evidence supports managing horses in as natural conditions as possible while meeting safety and health requirements.
