Why Does My Dog Lick My Armpits? (7 Reasons)

Our beloved dogs possess an array of charming quirks and characteristics that often leave us in wonder. Occasionally, we observe them engaging in behaviors we might deem peculiar or unusual, such as licking seemingly random objects. Have you ever caught your furry friend in the act of licking your armpits? This may prompt you to wonder about the underlying reasons.

Could there be significance behind your dog’s armpit licking?

The act of dogs licking your underarms can be attributed to several factors. It might be due to their enjoyment of the taste of your sweat or an attraction to the flavor of your deodorant. Alternatively, it could be an expression of affection, an instinctual grooming gesture, a sign of submissiveness, or a response to the attention they receive. Additionally, in the case of young puppies, it may simply be a matter of curiosity.

Let’s delve deeper into the seven reasons why your dog might lick your armpits and whether this behavior should raise any concerns.

Seven Reasons Why Your Dog Licks Your Underarms

It’s essential to recognize that there may be more than one motivating factor behind this behavior. Therefore, paying attention to the context and setting of the situation and behavior can help you discern the specific reasons influencing your dog’s actions.

Reason 1: Your Dog Enjoys the Taste of Your Sweat

What may not appeal to humans in terms of taste or smell might be quite delightful to our canine companions, including our sweat!

Sweat contains salt and acidic compounds, which may have an appealing taste for dogs. Given that dogs have fewer taste buds than humans and possess a different sense of taste, substances like sweat can be surprisingly appetizing to them.

You might observe your dog not only licking your armpits but also other parts of your body, such as your hands, face, and even your bellybutton. However, unlike these other areas, your armpits tend to emit a more potent scent and a more intense flavor. This could explain why your dog exhibits greater enthusiasm when licking your armpits, particularly after you’ve engaged in physical activity.

Reason 2: Your Dog Is Attracted to the Taste of Your Deodorant or Antiperspirant

As discussed in the previous rationale, your dog might indulge in armpit licking not only due to their fondness for your sweat but also because they find the taste of your deodorant appealing. While deodorants and antiperspirants are generally non-toxic, it’s essential to ensure your dog doesn’t ingest these products. Some specific ingredients in certain brands can be harmful if consumed by dogs, as they are not intended for ingestion by any means.

Interestingly, dogs may also be drawn to the scented skincare products you use. You might observe your dog licking your arms or legs because they appreciate the taste of your lotion.

Reason 3: Your Dog Wishes to Express Affection

Our cherished canine companions have their unique way of conveying affection, which often differs from our human means of expression. While we use words, they rely on actions to communicate their emotions. Licking is one of the most prevalent ways dogs demonstrate their affection. Hence, if your dog lavishes attention on your armpits, consider it their distinctive way of saying, “I love you.”

While licking serves as a universal sign of canine love, various breeds may exhibit their affection through distinct gestures. What’s heartwarming for a Boxer, for instance, might not align with the love signals of a German Shepherd. So, the next time your furry friend shows an affinity for your armpits, understand that it’s their way of letting you know they deeply care.

Reason 4: Your Dog Engages in Grooming Behavior

Dogs frequently employ licking as a grooming behavior, and your armpits might pique their curiosity in this regard. The unique scent emanating from this area, influenced by deodorants, antiperspirants, or lotions, may intrigue them, leading to a grooming response. If your pup concentrates on your armpits, it could be their way of “cleaning” you by removing what they perceive as foreign scents.

Beyond cleanliness, grooming signifies a dog’s expression of trust and bonding. When your dog chooses to groom you, it underscores the profound bond you share. Consider it a compliment to the trust and close relationship you’ve cultivated whenever your furry friend exhibits a keen interest in your armpits.

And remember, dogs aren’t the only pets with a penchant for grooming their owners! You can witness a pet rabbit displaying this endearing behavior in this video:

Reason 5: Your Dog Is Demonstrating Submissiveness

Dogs convey a myriad of emotions through their behaviors. While some actions may appear aggressive or destructive, many, like licking, serve as subtle indicators of their inner state. When your dog licks your underarms, it can be a way of expressing their submission.

This gesture is akin to a service, signifying their trust and vulnerability towards you. It’s their means of conveying, “I acknowledge your leadership and pose no threat.” In addition to armpit licking, other submissive behaviors may include crossed paws, a tucked tail, or lying belly-up in your presence.

Recognizing these signals is crucial for comprehending the extent of respect and trust your dog holds for you.

Reason 6: Your Behavior Encourages the Action

Our actions significantly impact our dogs’ behaviors. While we often associate rewards with treats, for many dogs, mere attention is a powerful form of reinforcement.

Could it be that your unintentional reactions are reinforcing your dog’s armpit-licking behavior? Every time they receive a response, whether it’s laughter, scolding, or even just a glance, it could be interpreted as attention, thus reinforcing their conduct.

This concept of positive reinforcement is also utilized in training, where a trainer might reward a dog with a treat each time it obeys a command, strengthening the desired behavior.

If you suspect that your responses are encouraging this behavior and you wish to discourage it, consider minimizing the attention you provide during these episodes. Simple actions, like briefly ignoring or creating distance when they attempt to lick your armpits, can convey that such actions will not yield extra attention.

Reason 7: Your Puppy’s Curiosity

Similar to human babies, puppies have a natural inclination to explore the world around them by touching objects and placing them in their mouths. Since dogs lack hands, they tend to investigate new things by using their mouths, which includes licking.

Therefore, it should come as no surprise that your puppy licks you, even if it means targeting your armpits. After all, everything is novel to them, and this behavior is a part of their exploration process.

Why Does My Dog Lick My Deodorant?

As we’ve previously discussed, dogs navigate the world primarily through their acute sense of smell and taste, which often drives them to explore scents and flavors that are foreign to them.

Your deodorant likely contains a distinctive blend of fragrances, salts, and other chemicals that might pique your canine companion’s interest. Some natural deodorants, with their more “natural” ingredients, could be even more enticing to dogs, as they may remind them of food.

Should You Be Concerned About This Behavior?

In most cases, your dog licking your armpits is harmless and driven by curiosity or a taste for the unfamiliar. However, prolonged exposure to deodorants or antiperspirants could potentially pose a risk due to toxic ingredients.

If your dog suddenly begins this behavior without prior interest, it’s advisable to consult a veterinarian. Any abrupt change in behavior should be taken seriously. Always reach out to your vet when you have concerns, as their primary objective is to ensure the well-being of your beloved pet.
