Dogs are just the most wonderful creatures to have around the house - a lot of unconditional love, boundless energy, and often a laser focus on something they really want. With my dog Edgar, it's food - he is lost to everything except the desire to get a mouthful or more of whatever he thinks my wife or I might share with him.
I'm not a dog expert, but what I do know is that dogs just don't have the kind of logic processing that humans do. It's why Edgar will beg for food that is no longer around - or why two dogs will do what they do on this video. These two just want to go outside, and are simply unaware that the patio door is closed and they will hit it. One does it, and It's like, "well, that can happen" - right? Well, a few seconds later, pooch #2 hits the same door in almost the same way. Why? Just let it be a canine version of a "sight gag" and leave it at that!
