If you’ve ever been greeted by a slobbery lick from your dog, you might have wondered, Why do dogs lick humans? While it might seem like a simple sign of affection, licking serves multiple purposes for dogs. This comprehensive guide explores the reasons behind this behavior, its potential meanings, and how to manage it if it becomes excessive.
Why Do Dogs Lick?
Dogs use licking as a form of communication, exploration, and bonding. While the reasons can vary depending on the situation, here are the most common explanations:
1. To Show Affection
Licking is often seen as a gesture of love and bonding. Puppies lick their mother and littermates as a natural way to strengthen family ties, and adult dogs carry this behavior into their relationships with humans.
2. Seeking Attention
Your dog might lick you to get your attention, especially if they’ve learned that licking elicits a reaction. Whether you pet them, laugh, or scold them, the attention reinforces the behavior.
3. Exploration and Taste
Dogs use their tongues to explore their environment. Human skin is salty and carries scents from our activities, making licking a way for dogs to gather sensory information.
4. Stress or Anxiety
Licking can be a self-soothing behavior for dogs. If your dog licks excessively, it could be a sign of stress, anxiety, or boredom. Licking releases endorphins, which can help them feel calm.
5. Instinctual Behavior
In the wild, dogs and wolves lick their pack members to communicate submission or to solicit food from adults. This instinctual behavior may carry over into domestic dogs.
6. Grooming and Care
Dogs lick themselves and others as a form of grooming. Licking you might be their way of showing care or “grooming” you as a pack member.
7. Medical Reasons
Sometimes, licking can signal a medical issue, such as:
- Skin Conditions: Dogs may lick itchy or irritated skin on themselves or their owners.
- Nausea: A dog feeling queasy may lick surfaces or people.
- Pain or Discomfort: Licking can be a way to cope with pain.
The Psychology of Licking: What It Means in Different Contexts
Understanding when and why your dog licks you can offer insights into their emotional state.
1. Licking Your Face
- Sign of affection and trust.
- Could be a remnant of pack behavior where puppies lick the faces of adult dogs.
- May be an attempt to taste or smell leftover food particles.
2. Licking Your Hands
- Hands carry a lot of scents from the environment, making them an interesting spot for exploration.
- May indicate a desire for attention or food.
3. Excessive Licking
If your dog is obsessively licking you or themselves, it could indicate:
- Anxiety or boredom.
- Underlying medical issues such as allergies or gastrointestinal problems.
- Compulsive behavior, which may require professional intervention.
Is Licking Always a Good Thing?
While licking is generally harmless, there are situations where it might be problematic.
Potential Risks of Licking
- Spread of Bacteria: Dogs’ mouths can harbor bacteria, and licking open wounds or sensitive areas could cause infections.
- Excessive Attention-Seeking: If licking becomes constant, it can be disruptive and indicative of unmet needs.
- Underlying Medical Issues: Persistent licking could signal a health problem that needs addressing.
How to Manage or Reduce Licking
If your dog’s licking is becoming excessive or undesirable, there are strategies to manage it:
1. Redirect the Behavior
- Offer a chew toy, puzzle, or other engaging activities to redirect their energy.
- Use training commands like “Sit” or “Leave it” to interrupt the licking.
2. Avoid Reinforcing Licking
- Do not reward licking with attention, even if it’s negative. Instead, ignore the behavior until it stops, then reward calm actions.
3. Identify Triggers
- Pay attention to when and why your dog licks. If it’s due to stress or boredom, address the root cause by providing comfort or stimulation.
4. Establish Boundaries
- Teach your dog that licking is only acceptable in certain situations by using consistent commands and rewards.
5. Address Underlying Issues
- If you suspect medical or emotional causes, consult a veterinarian or a professional dog behaviorist for guidance.
