Provided is a method, system and computer readable-medium to evaluate lameness in a four-legged animal. The method includes selecting a gait analysis test. Test data associated with the animal is collected for a plurality of gait cycles at a speed associated with the test. The test data is collected in relation to a pressure sensor pad having a plurality of sensors. A plurality of paws and associated paw pressure of the animal are identified in association with each of the cycles in relation to the sensor pad. A gait lameness score is computed in association with a paw based on a ratio of, a total paw pressure for the paw in the plurality of gait cycles divided by total pressure for the plurality of paws in the plurality gait cycles, and a mean paw pressure for the paw that is expected by a breed of the animal.
