Has your Cavapoo randomly picked up any funny new habits?

My 9 month old Cavapoo just started doing this cute thing where after he poops, he’ll dig with his back feet as if to cover up the poop with the mulch. One day he just started doing it. I don’t know if he saw another dog do it first and wanted to try it out or if it’s just random. Has yours ever started a new habit out of the blue?
