Doggos can be extremely smart, but sometimes our human ways and inventions are simply beyond their ken. Stairs, for instance: they are pretty bizarre for dogs, and they need to think a lot about them to understand how to use this adjunct to gracious living without falling.
This cute labrador pup is definitely gonna learn how to use stairs properly - someday. But for the time being, the little pooch is a bit puzzled, so it tries to move like a snake, and constantly forgets to use its legs. Don't worry, doggo - one day you will be big enough that you'll be able to leap over all those stairs in one bound!
