Digging After Going To The Bathroom
Similar to cats, dogs would dig the ground after pooping. But unlike cats, they do this not to cover their droppings but to spread their scent on the ground. It’s one way that they mark their territory. Other dogs would smell their scent on the ground.
Winking
Although winking might look like it’s another secret language of dogs, there really isn’t too much behind it. It’s more likely that they have something in their eyes that they have trouble getting rid of.
