Is it Good for a Dog to Lick Your Lips? Pros & Cons

As dog owners, we often find ourselves showered with affection from our furry friends. One common display of affection is when our dogs lick our faces, particularly our lips. 

While it may seem cute and endearing, there are important factors to consider when evaluating whether it is good for a dog to lick your lips. 

In this article, we will delve into the pros and cons of this behavior to help you make an informed decision about allowing your dog to lick your lips.

The Instinctive Behavior of Licking

Licking is a natural behavior for dogs that dates back to their wolf ancestors. Puppies lick their mother’s face to seek attention and communicate their needs. 

Similarly, adult dogs often lick their pack members to establish social bonds and show submission. 

It’s important to understand that when a dog licks, it is not always with the intent to harm or annoy but rather as a way to communicate and display affection.

Pros of Dogs Licking Your Lips

Social Bonding: Dogs view their human companions as part of their pack and licking can be seen as a gesture of bonding and affection. It can strengthen the emotional connection between you and your dog.

Endorphin Release: When a dog licks, it can stimulate the release of endorphins in both the dog and the person being licked. These feel-good hormones can promote relaxation and a sense of well-being for both parties.

Emotional Support: Many dog owners find comfort in their pets’ affectionate behaviors. Allowing your dog to lick your lips can provide emotional support and relieve stress, especially during challenging times.

Cons of Dogs Licking Your Lips

Hygiene Concerns: Dogs explore the world with their mouths, and their tongues can harbor bacteria, parasites, and allergens. Allowing your dog to lick your lips may introduce these microorganisms into your mouth, which can potentially lead to infections or allergic reactions.

Reinforcing Undesirable Behavior: If you reward your dog for licking your lips, they may interpret it as positive reinforcement, encouraging them to repeat the behavior excessively. 

This can be problematic, especially if you’re trying to discourage licking in certain situations.

Transmission of Diseases: Although it’s relatively rare, certain zoonotic diseases can be transmitted from dogs to humans through saliva. Conditions such as giardia, salmonella, and ringworm can pose a risk, particularly to individuals with compromised immune systems.

Mitigating the Risks

To strike a balance between the pros and cons, it’s essential to take certain precautions:

Training and Boundaries: Teach your dog appropriate behavior by setting clear boundaries. Reward them when they demonstrate calm and controlled behavior instead of excessive licking.

Regular Veterinary Care: Ensure your dog receives regular veterinary check-ups and vaccinations to minimize the risk of disease transmission.

Good Hygiene Practices: Maintain good personal hygiene by washing your hands and face after interactions with your dog, particularly if they have been licking or playing outside.


Allowing your dog to lick your lips can be a personal choice influenced by various factors.
