Dogs usually lick each other’s ears as a mix of grooming, affection, and communication, but sometimes it can signal boredom, anxiety, or even an ear problem in the other dog.

Quick Scoop

The main reasons

  • Grooming help : Dogs can’t easily clean their own ears, so a buddy may lick to remove dirt, debris, or earwax, just like social grooming in wild canids.
  • Affection and bonding : Ear licking is an intimate behavior that often shows trust, comfort, and friendship between dogs that live together or play often.
  • Social signals & hierarchy: Often the more submissive dog does the licking, using it as a polite “you’re the boss / we’re cool” gesture within their little pack.

The weirder-but-normal bits

  • They like the taste : Some dogs genuinely seem to enjoy the salty, waxy flavor and smell of another dog’s ears, so the behavior can become a quirky habit.
  • Self‑soothing or boredom : Repetitive licking can calm some dogs when they’re anxious or under‑stimulated, so an ear becomes their living stress ball or boredom activity.

When it might be a problem

  • Possible ear infection or irritation : If one dog suddenly becomes a magnet for ear-licking, or if the licking is intense and constant, it can mean there’s already an infection, moisture, or discharge that attracts the other dog.
  • Risk from overdoing it : Too much licking can irritate the ear skin and actually cause or worsen infections, so it’s smart to interrupt obsessive sessions and have a vet check the ears.

What you can do

  1. Watch the frequency: Casual, occasional licking between dogs that otherwise seem relaxed is usually harmless.
  1. Check the ears: Redness, odor, head shaking, or discharge are all “vet time” signs.
  1. Redirect if obsessive: Offer toys, play, or training games if one dog fixates on the other’s ears so it doesn’t turn into a skin or infection issue.

Bottom line: a little ear licking is normal dog social behavior, but obsessive or sudden changes are your cue to step in and get those ears checked.
