I have found that any official dog stairs are too narrow for my bully, Abby. She has such a hard time because of her age and joints, so we made some up. We got a Square leather step stool from Target and put it next to a covered bench at the end of the bed. She can maneuver up onto both of them then onto the bed. Bella is much smaller and younger, she can get up the dog stairs, we got the wooden ones with the storage bin from Pet Smart.
