Digging After Going To The Bathroom
Perhaps you assumed that a dog digging up grass after they use the bathroom in your yard or pavement was a way to “cover” their droppings. However, the truth is that this is a way for them to mark their territory! By doing such a thing, they are able to leave the scent of their paws on the dirt and let others know that they have been there. Perhaps they are also trying to claim that particular patch of grass.
Winking
No matter what you might think, a dog that winks at you is not one trying to tell a funny joke or hinting at something. The truth is that they probably just got something in the eye. It is very likely that this object bothers them or irritating their eyes in one way or another.
