What Do Dog Licks Really Mean?
It’s a common and often heartwarming behavior: your dog runs up excitedly and begins licking your face like there’s no tomorrow. Many pet owners interpret this as a dog’s version of kissing — a furry sign of love and affection. But is that really what’s going on? Let’s explore the behavior of dog licking from a biological and behavioral perspective to answer the question:
do dog licks actually mean kisses?
The Origins of Dog Licking
Licking is a behavior rooted deeply in canine biology. It starts in puppyhood when newborn pups are licked by their mother not only to clean them, but also to stimulate breathing and digestion.
- Instinctual behavior: Dogs are born with the reflex to lick, mirroring what they experienced from their mother.
- Pack communication: In wild canid packs, licking is a method of communication. Submissive dogs often lick more dominant members as a sign of respect or appeasement.
Licking as a Sign of Affection
Yes, in many cases, dogs do lick their humans to show affection. When your dog licks you when you're relaxed or playing, it often indicates a level of bonding.
- Positive reinforcement: If licking you results in petting, praise, or even laughter, your dog learns that this action gains your attention and approval.
- Oxytocin release: Interactions like licking — similar to petting — can release oxytocin, the “love hormone,” in both you and your dog.
Other Reasons Dogs Lick
However, licks aren’t always signs of adoration. There are several other reasons why your dog might be licking you or objects in the environment:
- Taste: Dogs might simply enjoy the salty taste of human skin or residues like lotion or food.
- Exploration: Dogs use their mouths and tongues to explore their surroundings, much like we use our hands.
- Anxiety or stress: Licking can be a self-soothing behavior. Dogs may lick repetitively if they feel anxious or nervous.
- Medical issues: Excessive licking — especially of objects or themselves — might be a sign of underlying health problems, gastrointestinal issues, or allergies.
Understanding Context Matters
To truly understand why your dog is licking, pay attention to the circumstances:
- Is the environment calm, or is your dog trying to comfort you (or themselves) during moments of tension?
- Is the licking focused on a wound, either yours or their own?
- Does it happen during play, quiet time, or after you’ve applied a new lotion or cream?
Reading your dog’s body language can provide many clues to their motivations.
When Is Licking Problematic?
Although licking is usually harmless, there are scenarios where it might become problematic:
- Compulsive licking: Persistent licking of surfaces, people, or themselves can stem from anxiety disorders and may require behavioral intervention.
- Open wounds: Dogs licking open wounds (yours or theirs) can cause infection and delay healing.
- Allergies or irritations: Overlicking specific areas of their own body could indicate itching or irritation that needs veterinary attention.
Should You Let Your Dog Lick Your Face?
While it’s generally safe, be mindful of hygiene concerns. Dogs carry bacteria in their mouths that may not be harmful to them but could affect humans — especially young children, elderly individuals, or those with weakened immune systems.
To balance affection with health considerations:
- Redirect licks to your hand instead of your face.
- Keep up with your dog’s dental hygiene.
- Wash after being licked if you have any cuts or sensitivities.
