During a horse lameness examination, why is observing on different surfaces such as grass and concrete helpful?

• A. It is the best time to shoe the horse
• B. It confuses the source
• C. Different surfaces stress different tissues and help pinpoint the source
• D. It takes longer

Answer: (C)

Observing on different surfaces tests how changing the load and concussion through the limb alters the horse’s gait, which helps locate the source of soreness. A soft surface like grass absorbs more shock, which can lessen or mask subtle signs of lameness, while a hard surface like concrete increases impact and can exaggerate or reveal problems in the limb. By comparing how the horse moves on both surfaces, you can see where the lameness is most pronounced and whether it’s tied to structures that bear more load or respond to impact. This variation helps distinguish whether the issue is related to the hoof and distal tissues or deeper structures up the limb, guiding further diagnostic steps.
