I like the concept of pet stairs, especially to get on the bed. However, only one of my chihuahua's will use it. The older one (13 yrs) is a little apprehensive. She refuses to use the stairs. We have stairs going down to the basement and she uses them but I think the steps on the pet stairs is a little too shallow for her to be comfortable on them. The younger chihuahua (9 yrs) goes up and down them constantly and seems to love them.
