Dog gait is fascinating. My dog "single tracks" -- his front and rear prints converge. As he walks faster in snow (so I can see it), the prints converge from : : to . .
In snow, it is obvious why this is advantageous. And yet I've never seen a museum use this print pattern in their "follow the stickers to a display" tricks.
You can kind of see the principle in a photo on his (very old) page: http://corvis.catell.us/
When he runs free, it is a straight line of four prints and then a body length: . . . . . . . .
I'm surprised I can't easily find pictures of this. German Shepherds do this, as do many other dogs. http://www.dpca.org/JEC/illustrated_standard/Gait/gait.htm
