I own a Chihuahua and have taken the stairs when he was still a baby, for him up the stairs was so self-evident. Really understood that he, the stairs needs as a small dwarf, he has but only when he jumped down the couch and is popped with the snout to the ground. Since the howling was big and since the stairs shall be taken, if he has quite a hurry. I prefer it alone so already, because I find small dogs should not constantly jumping, is not good for the joints.
The staircase is so in my opinion for Chihuahuas, Yorkshire Terrier, small poodle, Maltese, Dachshund and co. In my uses it at least very grateful :)
