She is very cute! However, I do want to point out a few things. What is that carpet looking material? I would remove it ASAP. She could (and probably will) begin chewing it and ingest the fibers. This could be very dangerous as it could lead to an impaction, which is very serious and can be deadly.
The wheel she will quickly outgrow. They are too small for full grown chins and it can cause her to run in an awkward position, and put strain on her spine. They also break easily and she could also chew the plastic on that. I have had a chin get an impaction as well from plastic. The wheels most people use that are safe for chins are the 15" Chin Spin and the Flying Saucer (metal, not the plastic ones in pet stores.)
