I am discovering that where one lives on two levels, and where occupants of the house are equal to or less than the number of dogs in the house, it is not physically possible for a person to exist on a floor of the house which does not contain at least one dog.

It doesn’t matter if one of them is sleeping in an entirely different room when you change floors, or scratching an itch. They come running. I think that if I tried to go down or up the stairs and didn’t hear a frantic “thump thump thump thump” behind me as the dogs raced to get to the next floor at the same time as myself, I’d be confused and possibly would experience vertigo.
