They’re Helping You Out
Your dog sees you as a member of their pack, so it’s only natural for them to want to make sure you don’t suffer from any uncomfortable itches or dirt in your ears, either.
They’re Being Submissive
Submissive licking is a normal and social aspect of a dog’s life, so feel free to let them tell you how much they respect you by giving your ear a patina of slobber.
They’re Feeling Secure
Grooming in this manner can also indicate that your doggo is feeling content and secure, and that they really love you.
They’re Trying to Comfort You
A lick to the ear might be an attempt on their part to comfort you and make you feel better.
Dogs don’t only use their noses to explore their world but also their tongues. They can pick up some information by licking or chewing more efficiently than when sniffing.
