Abstract: A staircase for installation onto a vehicle is disclosed herein. The staircase includes an attachment-mechanism, a first-step and a second-step. The first-step and the second-step are pivotally connected such that the staircase is able to move between a folded-position and an unfolded-position. The staircase offers an effective method for loading elderly or disabled dogs into vehicles without strain on the pet owner and prevents the pets from scratching the paint of a vehicle as they enter or exit.
