While Weimaraner size may assist in the performing of tasks of a sporting dog, it also makes the breed more susceptible to hip dysplasia. However, this breed has a lower rate of dysplasia. This may be due to selected gait velocity and mechanics specific to the breed, but gait analysis of Weimaraners is lacking. Study objectives were to define normal trotting mechanics and to determine the influence of velocity on gait. Dogs were trotted at a slow and fast trot and at both velocities. The trot had a diagonal footfall sequence with a 2-beat rhythm alternating between diagonal bipedal support and suspension. Velocity increase was achieved with significant increases in stride length and head, withers, fore, and hind paw displacements (P < 0.05). Range of motion of the elbow and hip significantly increased with increasing velocity (P < 0.05). These parameters will assist in gait evaluation and detection of lameness.
