This study was conducted to find out the compensation strategy through kinetic gait analysis by comparing dog with congenital luxation of the shoulder joint and normal dog. Ground reaction forces were recorded for all limbs while normal poodle dog and poodle dog with shoulder joint luxation was allowed to walk on an instrumented platform. The dogs were evaluated for maximal vertical force (MVF), body load distribution (BLD), and symmetry index (SI). The MVF was increased in the contralateral forelimb of luxated shoulder joint. The SI was also increased in a dog with dislocated shoulder joints in the forelimbs. For BLD, the maximum load distribution increased centrally, but the total load distribution decreased in the ipsilateral forelimb paw. In contrast, total load distribution was increased in the contralateral forelimb paw. During forelimb lameness, changes in weight-bearing load showed compensatory load redistribution. These biomechanical changes may lead to changes in the musculoskeletal system in a dog with luxated shoulder.
