Why Does My Dog Have To Lick My Face. Think of this as the doggy equivalent of social kissing. Dogs lick because they are curious to know how you are feeling and where have you been.

It’s a natural greeting for your cat. This is not always something obvious, like the burr between his toes. Dogs who aren’t appreciated enough will likely to lick their pet’s faces prior to going to bed because they find it relaxing and comforting for themselves.
