I think it would help if the stairs were a little deeper, and spaced a little farther apart so the climb is more gradual. So far my dog won't use it.  I purchased it to help him get up on the bed, since one of his hind legs is a little arthritic.  He sniffed the steps, then walked to another section of the bed and jumped up on it without using the steps.  Maybe over time he'll get used to it, and I'll try enticing him with some treats.  But I fully expected that he would walk up these steps just like he does any other.  No luck, at least so far.
