Loading and travelling in a horse trailer causes significant stress for many horses, with welfare implications from fear, injury risk and chronic aversion to handling.
Many horses experience loading and transport as highly aversive due to fear, physical discomfort and restricted movement. Traditional approaches involving force (ramps pushed behind horses, people chasing horses on) create fear-based aversion that worsens over time. Evidence strongly supports systematic desensitisation and counter-conditioning approaches that build positive associations with the trailer gradually. Journey welfare depends on appropriate space, ventilation, food and water access and regular rest stops. The welfare investment in good loading training pays dividends in reduced stress and injury.
