In the silence between a horse and its pain lies one of veterinary medicine's oldest dilemmas: how to know what a creature cannot say. Researchers at Adelaide University tested whether blood-borne immune signals might serve as a proxy for suffering in horses with gastric ulcers — a condition found in nearly every racehorse — only to find the test could not distinguish the sick from the healthy. The failure is not a dead end but a clarification, narrowing the field of possibility and reminding us that understanding animal suffering demands methods as particular as the animals themselves.
