why do dogs sometimes walk around in a circle before they lay down?

I notices that my dogs recently started walking in a circle before they lay down. Why is that?

It's a throwback to before they were domesticated. When laying prone, they want to be sure nothing is behind them to sneak up and...eat...them while they rest. If they just started doing it, their hearing or vision might be going. It's nothing to be alarmed about.
