Why does it have to be Boston Dynamic? There are lots of robot dogs out there now. I also agree with all the good points made by others already about low gravity (these dogs took a long time to get trained well against Earth's gravity, they won't "just work" on Mars or the moon). Wheels have their problems but are also very simple and hence fewer ways to fail.
