Isn’t it funny how animals don’t look each other in the eye, really? Maybe only humans do, maybe only humans really recognize each other. It’s like this photo, where the kittehs are "yaahm"ing away on their lollipop, not looking at each other. Same is happening here—the horse and puppeh are all "snort!" and "ew!!!" respectively, and not looking each other in the eye.
That puppeh is totally freaking out man! Thanks to Lori S.
