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".

The conversations probably went something like this:

Apprentice: You wouldn’t believe what I saw on Facebook last night!

Sue Dyson: Double video explanation of equine ethogram for recognizing lameness and pain

Bad behavior or signs of pain? All the facial expressions shown here are part of the ethogram developed by Dr. Sue Dyson's research team at the Animal Health Trust in England. In a continuation of the research, recognition of facial expressions in both ridden and unridden horses has been recommended as a way to identify potential lameness, not just "naughty" behavior, with larger welfare implications.

Researchers at the Animal Health Trust (AHT) Centre for Equine Studies in England have produced a practical tool to help owners, riders, and professionals recognize signs of pain by observing a horse’s facial expressions. The second part of the study was published recently, along with a new video, with a focus on facial expressions relationship to lameness. Both videos are included in this article.
