Ridden Horse Ethogram: New Sue Dyson study confirms viability of behavioral observation system to identify musculoskeletal pain in horses under saddle

This horse is demonstrating signs of musculoskeletal pain as described by the Ridden Horse Ethogram: 1) Ears are behind the vertical for more than five seconds; 2) Intense stare; 3) Mouth is open, exposing teeth for ten seconds; 4) Hindlimb toe drag.

As flight animals, horses instinctively remain silent in the face of pain, A new study, published earlier this month by Dr Sue Dyson in the peer-reviewed journal Equine Veterinary Education, shows that they however do have a "voice" if observers are trained to "listen".
