Why Do Dogs Lick People?

Dogs licking people is a common behavior that is often seen as a sign of affection. It can also be a way for dogs to communicate or express submission, as well as explore their environment through taste and smell.

Why This Happens / Why It Matters

Communication and Bonding

Licking is a natural behavior for dogs and plays a significant role in canine communication. Puppies lick their mothers to encourage care and feeding, and this behavior often extends into adulthood as a way to bond with their human companions.

Sensory Exploration

Dogs have an acute sense of taste and smell, and licking is an extension of this sensory exploration. By licking, dogs gather information about their environment and the people in it, which can be particularly important in understanding their surroundings.

Behavioral Significance

Licking can also indicate submission or a request for attention. In some cases, dogs might lick excessively due to anxiety or stress, which could require behavioral intervention.

Research-Backed Key Points

A study published in the Journal of Veterinary Behavior found that licking is often a calming signal in dogs, helping to reduce stress in social situations.
Research from the American Society for the Prevention of Cruelty to Animals (ASPCA) suggests that dogs lick people as a learned behavior reinforced by positive attention.
According to a paper in the Journal of Applied Animal Welfare Science, excessive licking can be a sign of compulsive behavior in dogs, often linked to anxiety.

Practical Tips

Reinforce Positive Behavior: Reward your dog when they display affection in ways other than licking to encourage a variety of bonding behaviors.
Monitor for Changes: Pay attention to any increase in licking, as it could signal stress or health issues.
Provide Mental Stimulation: Engage your dog with toys and activities that can help reduce excessive licking caused by boredom or anxiety.

Common Myths or Mistakes

All Licking Means Affection: Not all licking is purely affectionate; it can also be a sign of submission or anxiety.
Ignoring Excessive Licking: Failing to address excessive licking can lead to further behavioral issues.
Using Licking as the Only Bonding Time: Encourage diverse forms of interaction to strengthen bonds.

When to Seek Help / Warning Signs

Excessive or Compulsive Licking: If your dog licks themselves or others excessively, it might be a sign of anxiety or a medical condition, and consulting a veterinarian or animal behaviorist is advisable.
Licking Accompanied by Other Symptoms: If licking is paired with other symptoms like loss of appetite, lethargy, or visible distress, seek professional advice.
