Just what my wife needed.  We have two huskies @ 9 & 10 years old.  They are starting to have trouble jumping into the back of her dodge Journey.   Now they can just walk up the ramp.  The length is just right so the bumpers that keep it from sliding are firmly set on the ground and the back floor of the S.U.V., and the non-skid surface is the right amount of traction.
