Why Do Dogs Kick Their Feet After Pooping and Peeing?

It is normal for dogs to vigorously kick the ground with their hind legs after defecating. This is called scraping or peeling out. Some dogs will also do it after urinating.
When a dog kicks or scratches the ground immediately after defecating or urinating, it is not trying to wipe the paws clean. Dogs tend to spread their paws out sufficiently so that they do not risk stepping into the poop. Dogs tend to clean their body parts, including their paws, by licking them. Although dogs may kick grass, dirt or other material onto the stool, they do not try to cover feces in the way cats do, because stool piles and scratch marks are so essential for canine communication.
