These stairs are perfect for our 95 pound Chinook! They are study and fit perfectly at the end of our bed, which has a high rise. It took very little training to get Lona to go up the stairs instead of jumping up on the bed. (We are trying to "save" her hips from wear, considering her size.) We still need to train her to use them to go down the stairs but don't anticipate any difficulty. Don't let the "pup" in the name of the product fool you!
