Vet Approved Guide: Why Do Dogs Lick Your Face? Behavior, Science & What It Means (2025)🩺🐶

By Dr. Duncan Houston BVSc

Dogs lick. A lot. And for many pet parents, one of the most common (and sometimes confusing) expressions of this behavior is the full-face lick attack. But is it affection, submission, communication, or something else entirely? As a veterinarian, I often explain that licking is a deeply ingrained, multi-functional behavior that varies depending on your dog’s mood, training, and history. 🐕❤️

Let’s explore the science and emotional motivation behind why dogs lick our faces—and when you might want to set boundaries. 👅🐾

🧠 The Top Reasons Dogs Lick Your Face

1. 🫂 Affection and Bonding

Face licking is often a dog’s way of saying, “I love you!” In packs, dogs lick to bond and show submission to higher-ranking members. Your pup may be showing respect and affection toward you as their favorite human. 🥰

2. 🍽️ Taste and Curiosity

Dogs love salty skin, food residue, or even the scent of your moisturizer. Your face may simply smell intriguing or delicious, especially after meals or workouts. 🧂🍗

3. 🐾 Learned Behavior (Reinforcement)

If licking your face leads to laughter, petting, or playful interaction, your dog learns that it gets attention—and that behavior is reinforced. This is one of the most common reasons face licking persists. 🧠🔁

4. 😬 Stress or Anxiety Relief

Repetitive behaviors like licking can soothe nervous energy. Some dogs lick to self-soothe when feeling overwhelmed. If your dog’s licking is frequent, frantic, which contain L-theanine and chamomile. 🌿

5. 👶 Puppy Instincts

In the wild, puppies lick their mother’s mouth to prompt regurgitation and show submission. This behavior carries over into adulthood and may explain licking around your mouth or chin. 👶🐾

6. 💡 Checking on You

Some dogs lick when they sense emotional shifts or illness. Studies show dogs can detect changes in human hormones and moods. Face licking could be their way of checking your wellbeing. 🩺

🔍 Is Face Licking Safe?

In most cases, face licking is harmless. However, there are a few considerations:

• 🦠 Germs: Dog saliva can carry bacteria (like Pasteurella or Capnocytophaga) that may pose risks to immunocompromised individuals
• 👶 Children: Young kids may be more vulnerable to bacterial transfer or startle responses
• 😷 Wounds: Never let your dog lick an open cut—this can cause infection

If you’re concerned, you can gently discourage face licking while still maintaining affection. Learn how below! ⬇️

🙅 How to Set Healthy Boundaries

1. 🛑 Teach “No Lick” or “Enough”

Use clear, consistent cues to mark unwanted behavior. Immediately redirect your dog to another activity or toy. 🎯

2. 🎁 Reward Calm, Non-Licking Behavior

Use treats or praise when your dog shows affection without licking. Reinforce what you want to see! 🧀🧠

🧬 Breed-Specific Insights

Some breeds are naturally more “licky” than others. These pups tend to be more affectionate, oral, or attention-seeking:

• 💋 Labrador Retrievers
• 🐕 Golden Retrievers
• 🎭 Pugs and French Bulldogs
• 🧸 Cavalier King Charles Spaniels
• 🌪️ Jack Russell Terriers

While licking isn’t inherently “bad,” teaching balance helps maintain respectful boundaries, especially with guests or children. 🧠🧍♀️
