The person who uploaded this video to YouTube gave it the title, "Dog doesn't understand how to go up stairs," which frankly we find a bit judgmental and reductive. When you watch the video, you will see that the dog negotiates the stairs perfectly well, but backward. How can someone say it doesn't understand how to climb stairs when it started at the bottom, and now it's here (at the top)? Let's not sniff at those who think outside the box. Cheers to you, dog, for discovering the pleasures of non-comformity, and not climbing the stairs a certain way just because "society" tells you to.
