Well, how would it work? You'd have to have a bit of the animal that would be separate, detached from the other bits. But then how would that bit get nutrients and oxygen?
​
Also what good would it be? Most terrain is unsuitable for wheels. That's why we build roads.
​
Also, what would it evolve from? If you're talking about "animals we can pet and cuddle with", that would be vertebrates, right? Well, where are the potential precursors to a wheel in vertebrate anatomy? How would they replace legs?
