Horse Pain Recognition and Welfare

Horses mask pain as a survival strategy. The Equine Pain Scale and Horse Grimace Scale help owners and vets recognise and treat pain in horses more effectively.

Key Facts

The Horse Grimace Scale validates pain assessment from facial expressions in horses
Stoic horses may not show obvious pain behaviour until conditions are severe
Lameness affects around 10% of UK horses at any given time
Colic - abdominal pain - is the leading cause of horse death in the UK
Musculoskeletal pain from poor saddle fit, dental problems, or back pain often manifests as ridden behaviour issues

Welfare Considerations

Horses evolved as prey animals and naturally mask pain to avoid appearing vulnerable. This creates significant welfare risks - horses suffering from chronic pain may appear normal to owners who are not looking for subtle signs. Facial expression changes (tight muscles around the eyes, flattened nostrils), behavioural changes (reduced activity, reluctance to work, irritability), and changes in movement pattern are all indicators of pain that owners can learn to recognise. The Horse Grimace Scale provides an evidence-based tool. Treating the underlying cause of pain improves welfare and usually resolves performance problems that were actually pain responses.

What You Can Do

Learn the Horse Grimace Scale to better recognise pain in horses in your care
Treat unexplained ridden behaviour problems as potential pain indicators first
Schedule regular dental, saddle fit, and veterinary checks to identify pain sources
Use the Horse Grimace Scale app to monitor your horse between vet visits
Advocate for pain recognition training to be included in all equestrian coaching qualifications
