Navicular disease presents as a chronic forelimb problem where pain is centered in the navicular apparatus, leading to a characteristic set of gait and stance changes. The horse often shows a shortened stride on the affected limb because the painful navicular region makes propulsion and weight bearing uncomfortable. To minimize pressure on the heel area, the horse may land toe-first, which can cause toe bruising from repetitive concussion. Radiographs often reveal changes in the navicular bone, reflecting degenerative or structural alterations in the surrounding supportive structures. If the condition affects both forelimbs, the horse may adopt a sawhorse stance, standing with the legs spread and weight distributed to reduce stress on the painful navicular region. All of these features together—pain in the navicular area, shortened stride, toe-first landing with toe bruising, radiographic bone changes, and a sawhorse stance—fit navicular disease.
