Dogs frequently express themselves through licking, a behavior that can range from endearing displays of affection to indicators of deeper behavioral or medical concerns. Understanding the nuances behind why a dog licks can significantly enhance the bond between pets and their owners, fostering a more harmonious environment. This comprehensive guide explores the various motivations behind this common canine action, drawing upon expert insights to help pet parents interpret their furry companions' signals and address any related issues effectively.
The Intricacies of Canine Licking: A Deeper Dive
The act of a dog licking its human companion, often affectionately termed 'doggy kisses', is a complex behavior rooted in both instinct and learned responses. Dr. Stefanie Schwartz, a board-certified veterinary behaviorist and the visionary behind Civilized Pet, highlights that licking is an innate behavior dogs learn during their formative puppy stages, playing a crucial role in canine communication and maternal bonding. It serves as a vital channel for dogs to convey their needs and emotions to humans.
Among the primary reasons dogs engage in licking is the profound expression of love and affection. From their earliest days, puppies receive licks from their mothers, a fundamental act of nurturing and stimulation that solidifies their bond. This deeply ingrained behavior naturally extends to their human families, as dogs are inherently social and affectionate creatures. Such interactions are not only pleasurable but also beneficial, as studies reveal that these shared moments of bonding can lead to reduced stress levels, or lower cortisol, in both dogs and their human counterparts. While embracing these affectionate gestures, it's also essential to establish healthy boundaries.
Beyond affection, dogs may lick as a form of 'allogrooming,' a social behavior observed among canines where they groom each other. This practice reinforces trust and strengthens social ties, making it a natural extension for dogs to 'groom' their favorite humans, viewing it as another way to show care.
Licking can also be a clear bid for attention. A dog persistently trying to lick you while you're preoccupied might feel overlooked. Dr. Rachel Malamed, a specialist in veterinary behavior, cautions that this attention-seeking behavior can become reinforced if the dog consistently receives a desired response, such as petting. While it's nearly impossible to ignore a dog's slobbery advances, responding to them can inadvertently encourage more frequent licking.
Boredom or anxiety are further drivers for excessive licking. Dogs, particularly working breeds like German Shepherds, Golden Retrievers, and Labradors, require substantial physical and mental stimulation. Without adequate exercise or engagement, they might resort to licking themselves, objects, or people excessively as a coping mechanism, potentially leading to destructive behaviors.
Furthermore, licking serves as a greeting ritual. Borrowed from their ancestral wolf behaviors, dogs lick each other and humans as a way to say 'hello.' Jen Gumas, a certified professional dog trainer, explains that wolves returning to their pack often lick others, sometimes even inside their mouths, to gather information and demonstrate submission. This instinct translates to dogs attempting to lick human faces, often targeting the mouth area.
In some instances, licking can signify medical issues. If a dog frequently licks unusual surfaces like floors or walls, it could indicate underlying gastrointestinal problems or compulsive disorders. Dr. Schwartz notes that air licking can also be a sign of nausea. Consulting a behavioral veterinarian is crucial for diagnosing and treating such conditions.
Finally, the simple truth might be that you taste appealing to your dog. Salty skin, especially in areas prone to sweat, or lingering food aromas can attract a dog's tongue. Sometimes, dogs lick to 'taste' where you've been, gathering information about your day through scent.
Recognizing the context of your dog's licking is key to understanding its meaning. While often a sign of affection, a sudden increase in licking, particularly if accompanied by signs of discomfort like a tense body, tucked tail, or lowered posture, warrants attention. It's important to differentiate between affectionate licks and those signaling stress, anxiety, or even a 'kiss to dismiss,' where a dog licks to politely request that an uncomfortable interaction cease. Given that dog mouths contain a multitude of bacteria, individuals who are immunocompromised should exercise caution with dog licks, especially on or near the face, to avoid potential infections.
