The steps are stronger than I anticipated.   We use these steps for our 65 pound Pit Bull to access the back yard.  The depth from floor to ground level is almost 38 inches.  Presently there are no permanent steps in place to access the back yard.
     The deluxe doggie stair is a great temporary fix until permanent steps are installed.  We no longer have to brave unpleasant climatic conditions in order for our pet to access the back yard.
