Answer to:
After my dog has done his business outside, he scratches his feet across the floor in the house and flicks mud and grass everywhere. Why does he do this? Actually it is a territorial thing, and contrary to what others have posted, they are TRYING TO GET THEIR SCENT ON THEIR FEET! This behavior is also prominent in large wild cats such as lions. When lions patrol their territory borders they often spray landmarks to warn other groups of their boundaries. After they have sprayed, they do the foot motion in the same way that you see your dog doing....
