Why Do Dogs Lick Humans? Exploring the Fascinating Reasons Behind This Behavior

Chances are, if you’re a dog owner, you’ve experienced the endearing (or sometimes slightly gross) sensation of your furry friend’s tongue on your skin. But have you ever stopped to wonder why dogs lick humans? While it may seem like a simple act, the reasons behind this behavior are actually quite fascinating and varied.

The Affectionate Lick: A Sign of Love and Bonding

One of the most common reasons dogs lick their human companions is to show affection and strengthen the bond between them. According to curiosityaroused.com, licking is a comforting and instinctive action that reminds dogs of how their mothers treated them as puppies. It releases dopamine and endorphins, creating a sense of pleasure and well-being for both the dog and the recipient.

Karen B. London, a certified professional dog trainer and author, explains, “Licking is a natural behavior for dogs and can be a way for them to show affection and bond with their human family members.” This behavior can be traced back to the earliest stages of a dog’s life when they would lick their mother’s face to stimulate her to regurgitate food for them.

The Empathetic Lick: Understanding and Comforting Emotions

Dogs are known for their incredible ability to sense and respond to human emotions, and licking can be a way for them to express empathy and offer comfort. Research shows that dogs are more likely to lick their owners when they appear visibly upset or distressed.

Dr. Brian Hare, an expert on dog cognition and co-founder of the Duke Canine Cognition Center, notes, “Dogs have evolved to be highly attuned to human emotions and behaviors. Licking may be their way of trying to console us or offer reassurance when we’re feeling down.”

This empathetic licking behavior is a testament to the deep connection between humans and their canine companions and highlights the incredible emotional intelligence of dogs.

The Attention-Seeking Lick: A Cry for Playtime or Treats

While licking can often be a sign of affection, it can also be a way for dogs to seek attention from their owners. Dogs quickly learn that licking can be an effective way to get their humans to interact with them, either for playtime, treats, or simply to receive some much-desired pets and scratches.

According to Dr. Stephanie Borns-Wingle, a clinical instructor at the Cummings School of Veterinary Medicine at Tufts University, “Dogs may lick to get attention or resources, such as food or access to a certain area. They may also lick as a way to solicit play or other social interaction.”

If you notice your dog licking excessively, it could be their way of saying, “Hey, pay attention to me!” In these cases, it’s important to provide your furry friend with the attention and stimulation they crave through playtime, walks, or training sessions.

The Taste-Driven Lick: Exploring Flavors and Scents

Dogs have an incredible sense of smell and taste, and sometimes, they simply can’t resist the temptation to lick surfaces or objects that pique their curiosity. This behavior is often driven by the natural salts and oils present on human skin or the scents of lotions, perfumes, or even the remnants of food.

Dr. Alexandra Horowitz, head of the Horowitz Dog Cognition Lab at Barnard College at Columbia University, explains, “Dogs have a keen sense of smell and taste, and they may be drawn to lick certain areas because of the flavors or scents present on the skin.”

While this behavior may seem odd or even gross to us humans, it’s perfectly natural for dogs and is simply a way for them to explore and experience the world around them through their highly developed senses.

The Compulsive Lick: Addressing Excessive Licking Behavior

While licking is generally a harmless and natural behavior for dogs, in some cases, it can become excessive and indicative of underlying issues. Excessive licking can be a sign of boredom, anxiety, stress, or even obsessive-compulsive disorders.

If you notice your dog licking excessively, to the point where it’s causing skin irritation or disrupting their daily routine, it’s important to seek guidance from a veterinarian or a certified animal behaviorist. They can help identify the root cause of the behavior and provide appropriate solutions, such as environmental enrichment, behavior modification techniques, or even medication if necessary.

Dr. Kelly Ballantyne, a board-certified veterinary behaviorist, advises, “If you’re concerned about your dog’s licking behavior, keep a record of when it occurs, what triggers it, and how long it lasts. This information can be incredibly helpful in determining the underlying cause and developing an effective treatment plan.”

Conclusion

Dogs lick humans for a variety of reasons, ranging from affectionate displays of love and bonding to attention-seeking behaviors or simply exploring the world through their keen senses of smell and taste. While licking is generally a harmless and natural behavior, excessive licking can sometimes indicate underlying issues that require attention.

By understanding the fascinating motivations behind this behavior and seeking professional guidance when necessary, we can strengthen our bond with our furry companions and ensure their well-being. So, the next time your dog plants a slobbery kiss on your cheek, take a moment to appreciate the incredible depth of communication and connection behind this simple act.
