Most of the time, dogs licking each other is simply a sign of affection. Dogs already have a way of communicating with each other, but they also use their tongues to express themselves. They lick one another for reasons such as grooming, licking wounds, showing affection, or simply getting to know one another better.
So when your dog licks another dog’s ears, you shouldn’t be alarmed, especially if the whole act was gentle and without any problems. If the licking behavior is aggressive, however, you should immediately separate them and call a vet to check for two possible reasons:
Dogs have ear wax glands that produce a light waxy substance to prevent dust from going inside their ears. This substance also acts as their natural protection against bacteria and other germs. Ear infections are common in dogs because their ear canals are also quite long, just like ours.
These are small parasites that feed on the wax inside your dog’s ears, causing it to become red, swollen, and irritated. They look like tiny moving dots under a microscope or magnifying glass. Some breeds are more at risk of getting mites, especially those with long ears.

Dogs portray this kind of obsessive behavior towards others due to different reasons. It can be because of anxiety, dominance, excitement, fear, or stress.
