Rough differences in straddle exist between types ofgaits: the straddle decreases in width from walk to trot and then to gallop. When they walk, mammals leave a pattern consisting of two parallel rows ofprints. However, when they speed up, they leave other characteristic patterns indicative of the type of gait being used. We call these patterns groups. The group pattern is measured from the leading end of the pattern to the trailing end of the same pattern so as to include prints from all four feet.
This measurement must be recorded from the same point on the first print to the same point on the next print. I suggest that the trailing edge be used. The stride, as defined, includes two full walking steps. Other authors have used stride to refer to one step. After many years, I now prefer this definition because the stride during a normal walk then equals the body length of the mammal from its hips to shoulders and is directly indicative of the animal's size.
