I have a maltese/pomerainian who loves to be on the bed, and jump OFF the bed. If you have a small dog that thinks they can fly , you MUST get these, they will love you for it. Think of the height of youre dog compared to the height of youre bed, is it 2 maybe even 3 or even 4 times as tall as they are?? Then, think of yourself jumping off something that is double , triple or quadruple youre height,  a bunch of times each day .
 How long are your knees going to last for ??..........
These are really comfortable stairs for them,not like the steep narrow and shallow treaded products  you will find in youre typical pet store, that your dog will stand at the bottom of and look up at you like you are nuts if you think they are going to be going up .
Youre dog will be flying up and down these things in no time, and saving his health and you vet bills
