The 24 Behaviors of the Ridden Horse in Pain is a film that dares to challenge the way we look at "badly behaving" horses, and promotes the notion that lameness doesn’t start at the head bob. Through a six-phase study, spanning three years, and over 400 horses, Dr. Dyson and colleagues developed The Ridden Horse Pain Ethogram (RHpE), a tool to reliably predict lameness before the condition worsens into limping and other obvious signs of injuries. The Ridden Horse Pain Ethogram is a catalogue of 24 behaviors, which scientific studies have demonstrated can be associated with pain in the ridden horse. The majority of these behaviors are at least ten times more likely to be seen in lame horses compared with non-lame horses. The film follows Dr. Dyson and Dr. Jim Myers of Gold Coast Equine, as they examine and diagnose show jumper Lauren McMahon’s beloved mare Galina, who was not obviously lame, yet seemed increasingly unhappy under saddle. Lauren had “tried everything” to figure out what was wrong, including ulcer treatments, multiple joint injections and specialized shoeing but Galina only became more resistant under saddle. Galina’s story is not uncommon for horses that do not present with an obvious head bobbing lameness. Oftentimes these are horses that get labeled as “resistant,” “lazy,” and for horses that buck or rear from pain, “explosive.” Trainers often tell riders to “push them through it.” The film educates horse lovers on how to spot the early signs of pain while taking viewers on an emotional “ride” through the eyes of a young girl who loves her horse and will stop at nothing to try to figure out how to make her comfortable.
