We don’t believe in playing favors with your dogs, discriminating, or saying that one is smarter than the other. All dogs are equally sweet and lovable, and it doesn’t matter who’s smarter. Only, in this case, it’s hard to stand our ground on this point, since one of these bulldogs is clearly smarter than the other.
Dogs like to look outside the window since it gives them a sense of control; they want to be in charge of things and to know what’s happening around them. Looking outside the window allows them to keep an eye on the street and make sure nothing is out of the ordinary (or that they aren’t missing any action). This is probably what these bulldogs were doing, but only one of them realizes the point of looking out the window.
