I've been thinking about customizing some draft horses... so I went out to the pasture to do a little research. Please pardon the dirt. Pete, on the left, is a Percheron gelding. Titan, his best buddy, is a bay roan Clydesdale gelding. Pete has more width and bulk, while Titan is leggier and more narrow. Here I even noticed the difference in their faces—see the how the distance between their eyes are different, as well as from eye to nostril. Titan's tail is naturally long, whereas Pete's has been docked. Notice the different shaped hindquarters.
