Disclaimer: watch this video with a tissue at hand (read: a box of tissues). This poorly shot iPhone video clip made my big, brown puppy eyes water. Last summer I was but a baby pup, learning to chase my tail and walk down stairs. I didn’t have anyone to help me, so I had to learn for myself how to descend those wooden mountains. Now I jump down six at a time, but hey, I’m a big dog now. This big dog helps his puppy go down the stairs for the first time, and it is just precious. My human cried a sea of tears watching this clip with me.
