It's almost always a sign of dominance and marking territory. It's a sign of kicking up the grass, dirt and spreading his scent from his paw pads and/or pee/poo all over his territory to mark what he considers to be his. Some back-kick after play or excited activity or when feeling dominant over a toy/object in their possession.
