That picture is too cute.
I bought a tiny ottomon on clearance at target and put it next to the couch and Chloe used to use that to jump up on the couch. I also once bought a stair basket at target, like the type of baskets that sits on 2 steps of a stairway- well guess what? If you flip it upside down and put it next to a couch you have 2 steps for a dog.

It worked great! Chloe is big enough now that she can jump on the couch so we dont have anything in thier but I have the ottoman next to my bed so she can get up on it.
