I was afraid it would be to hard and long between steps  for my little apple-head Chihuahua she's only 3 pounds, but after I sat her On steps several times , she understood it was not going to hurt her and she is using it to get off of the bed and back on after she uses her pee pad, I remove it at night since,  she sleeps with me and not worry of her
Getting off bed while I sleep. She is so small, I barley feel her when she moves, I give this a high 
Marks and even told my sons girlfriend of it, since she needs one for her Chihuahua who is  little bit bigger than mine.
