Just got this for my bigger Springer Spaniel.  So far she has not used the steps, but over time she will figure it out and walk up and. into bed.  Both Springer go up and down stairs all day so I know there is hope.  
I have one other Springer and she jumps up without any problem.  I like the way is collapses but wonder about the locking mechanism.  Better than I expected, well put together with quality solid wood.  The carpet on the treads will help give them that little boost they need.
I would highly recommend this product.
