Dogs have their own unique way of saying hello, and licking is one of their most common forms of greeting. When one dog licks another, it’s often their way of reaffirming social bonds, much like humans shake hands, hug, or smile when meeting someone. Ear licking specifically can be seen as a friendly gesture that communicates trust and familiarity. This behavior is especially common in dogs that have an established relationship, such as siblings or housemates, as it strengthens their connection and sense of belonging within their pack.

Dogs have phenomenal senses, one of which is their sense of smell. Dogs can sense subtle changes in their environment and even in other dogs.

When it comes to ear infections, a dog may detect the presence of bacteria, yeast, or other irregularities in their friend’s ears long before any physical symptoms become obvious to humans. By licking, they may instinctively try to "help" address the issue, though this behavior is no substitute for proper treatment. If you notice persistent licking, it’s worth checking for signs of infection, such as redness, swelling, or an unpleasant odor.

Going back to dogs being pack animals, they respect a social hierarchy where some dogs take on dominant roles while others are more submissive. Submissive dogs often use body language to communicate their status, such as rolling onto their backs to expose their vulnerable areas. A dog can lick another dog’s ears as a way to show submission to another dog in the hierarchy. Licking another dog’s ears can be another way to signal submission and respect within the pack.

This reasoning may seem like an odd one but dogs may lick each other’s ears just because they like the taste. Just like how dogs can smell an ear infection in another dog, they can also smell everything else in their ear. They can be drawn to the ear wax, sweat, and oils that are produced in the ear and give off a strong scent and flavors that dogs find appealing. Ear wax is a salty substance that dogs love so if your dog is licking another dog’s ears, they may be enjoying themselves a little snack.

For dogs, licking is one of the most intimate ways to express affection and build trust. When a dog licks another’s ears, it’s often a sign of love and companionship. This behavior is especially common among dogs who are close friends, siblings or share a household. It strengthens their bond and fosters a sense of security within their relationship.

For some dogs, licking is more than just a way to interact with others—it can also be a form of self-soothing. The repetitive motion of licking, combined with the comforting sensory feedback, can help dogs manage stress, boredom, or anxiety. Just like humans might fidget or engage in repetitive habits when feeling uneasy, dogs may lick obsessively as a coping mechanism. However, if this behavior becomes excessive, it could indicate underlying issues that need to be addressed. Providing alternative outlets, such as engaging toys or additional exercise, can help redirect their attention and reduce compulsive licking.

Dogs can easily fall into various obsessive behaviors, and licking is among their most common. Initially, it may seem innocent or that they are addressing a specific issue, but soon you might notice it’s incessant and they can’t seem to stop. This behavior is often observed in shelter pets who lick or chew as a response to anxiety. In severe cases, some dogs have even chewed parts of their tails off. stop. This can often be seen in pets in shelters in the form of licking or chewing due to anxiety. It can even get so bad that some dogs have chewed part of their tails off.

While ear licking may seem harmless, it does come with some potential risks. The constant moisture from saliva can create an environment that fosters bacterial or yeast growth, leading to ear infections. Additionally, over-licking can cause irritation to the delicate skin inside and around the ears, which might result in redness, sores, or discomfort for the licked dog. If you notice your dog licking another dog’s ears incessantly or see signs of irritation, it’s important to intervene. Excessive licking could indicate an underlying problem, such as anxiety or even an undetected ear infection in the licked dog, both of which may require veterinary attention.

While occasional ear licking is normal, excessive or obsessive licking can signal a problem that requires action. If your dog can’t seem to stop, or if the recipient of the licking shows signs of irritation, such as shaking their head, pawing at their ears, or avoiding the other dog, it’s time to step in. Observe the licked dog’s ears for signs of infection, like redness, swelling, or an unpleasant odor. If you suspect an infection or the behavior persists despite redirection, consult your veterinarian for guidance. It’s always better to address the issue early to prevent complications and ensure both dogs remain happy and healthy.

If your dog is licking another dog’s ears excessively, redirecting their behavior is a gentle but effective way to break the habit. Offer them engaging distractions, like chew toys, puzzle feeders, or interactive play, to occupy their attention. Positive reinforcement can also work wonders—praise and reward your dog when they stop licking in response to your command. Consistency is key here, as reinforcing alternative behaviors will help them form new, healthier habits over time. Remember, the goal is to redirect without disrupting their natural social interactions entirely.
