Pity the poor dog who can’t figure out how to get up or down a flight of stairs. Some try it backwards, some sideways, and a few have even more creative approaches.
There is no truth to the rumor that Rutgers University is offering a four-year degree program in Going Up/Coming Down Stairs. I mean, not four whole years of it…
I would surmise that the dog whom back up the stairs do so because it allows them to face downward, which is their direction of greatest risk (from falling).
