The "misbehaving" performance horse: is it ever behavioral?

Summary

# Editorial Summary: Understanding "Misbehaviour" in Performance Horses Contino's review challenges a widespread assumption in equestrian practice: that poor performance or difficult behaviour in competition horses stems primarily from training, management, or temperament issues. By systematically examining the physical and medical underpinnings of what is commonly labelled "misbehaviour," the author demonstrates that the vast majority of performance problems originate from pain, discomfort, or physiological dysfunction rather than true behavioural pathology. The review synthesises evidence across musculoskeletal, neurological, gastrointestinal, and systemic conditions that manifest as rearing, bucking, refusing jumps, head-tossing, and other evasive behaviours—highlighting how diagnostic investigation and veterinary intervention are often the appropriate first step rather than intensified schooling or retraining. This distinction carries significant ethical implications for equine welfare and informs the veterinary profession's responsibility to advocate for horses before behavioural remediation is pursued. For farriers, physiotherapists, and coaches working alongside veterinarians, recognising this framework means prioritising comprehensive lameness and pain assessments when performance deteriorates, rather than assuming the horse is simply being difficult or testing boundaries.

Key Findings

• •Most behavioral issues presented by performance horses have underlying physical causes rather than true behavioral etiology
• •Veterinarians play a critical role in identifying physical causes masquerading as behavioral problems
• •Performance horses struggling with optimal performance often present with signs misinterpreted as behavioral issues
