Why Does My Dog Sniff My Face?

Your dog may sniff your face to pick up your scent, understand your emotions, strengthen your bond, understand you better, learn about your recent activities, self-soothe, or instinctually gather information.

To Pick Up Your Scent

A dog’s nose is capable of detecting subtle odor molecules that create your unique scent.

By sniffing your face, dogs can identify who you are. Your natural smells give dogs clues about your identity.

To Sense Your Mood

A dog can pick up on tiny chemical changes emitted when you experience different emotions.

By nosing around your face, dogs can get a read of your mood from smells that indicate contentment, anxiety, fear, and more.

To Monitor Your Health

Dogs are able to smell markers of illness in your scent that humans aren’t even aware of.

Frequently sniffing your face allows dogs to check your health status and notice if something may be amiss.

To Strengthen Their Bond With You

For dogs, sniffing is a way to gather evidence that you’re a member of their family and pack.

Your facial scents offer proof that you’re their loved one. Face sniffing reflects dogs’ attachment to you.

To Better Understand You

Overall, sniffing your face allows dogs to gain a deeper understanding of your identity, emotional state, health, and role in their life.

It’s a critical way they interpret you and the human world.

They Detect Food or Other Smells on You

Dogs may sniff your face to pick up traces of food, drinks, smoke, perfume, or other smells that provide information about where you’ve been and what you’ve consumed recently.

Their sensitive nose pinpoints scents on your skin.

To Learn About Your Activities

Your face collects smells from various environments and activities.

Dogs can get clues about where you went and what you did by sniffing—whether you took a walk, played at the dog park, worked in the garden, etc.

To Soothe Themselves

For some dogs, gently sniffing your familiar facial scent has a calming effect. The familiar smells provide comfort and reassurance when a dog is stressed.

Its Just Instinct

Face sniffing when you arrive home or when dogs meet you may stem from an instinctual greeting ritual common among canines.

They sniff to gather details about you as an individual.

Should You Let Your Dog Sniff Your Face?

You should let your dog sniff your face in most situations. This common canine behavior is natural and serves several beneficial purposes for your pup.

While face sniffing may seem intrusive or odd to humans, it provides critical information that helps dogs interpret and connect with you.

Your facial scents allow your dog to identify you, monitor your health, sense your mood, strengthen their bond with you, and more.

It is a primary way they gather details about you and feel close to you.

Though harmless in most contexts, you may want to limit face sniffing if your dog excessively paws at you or becomes too pushy.

Set boundaries without scolding them.

You can also gently block their access to your face when you don’t want to be sniffed.

Overall, frequent face sniffing is your dog’s innate way of getting to know you.

The complex smells collected on your skin, hair and breath offer an incredible amount of data to your dog that we can’t imagine.

It likely provides them comfort and insight they desperately need.

While you don’t have to allow face sniffing at all times, keeping an open mind about this common ritual will help you better understand your dog.

When To Worry About A Dog Sniffing Your Face?

Most of the time, you don’t need to worry about a dog sniffing your face. However, excessive, forceful, or out-of-context face sniffing could signal a potential issue requiring attention.

While natural dog behavior, unwanted face sniffing should be redirected.

Consistent boundary pushing, nose poking, or pawing at your face is problematic.

Dramatic changes in sniffing habits or aggressive leaning into your space warrant evaluation.

Excessive face sniffing may indicate anxiety, nervousness, or stress in your dog.

They may be seeking abnormal amounts of comforting scent input.

Compulsive sniffing could also reflect a neurological or sensory issue.

Observe what triggers intense sniffing and if it eases their worry.

Consulting a vet or trainer can help determine causes.

Likewise, a dog suddenly fixated on sniffing your face could be responding to changes in your scent from illness, pregnancy, or medication.

Dogs detect these shifts before humans.

But constant focus on your odors may mean monitoring you obsessively.

What To Do About Your Dog Sniffing Your Face

Generally, tolerate your dog sniffing your face in moderation. However, set boundaries around unwanted sniffing using positive reinforcement training and redirection.

Try To Identify Why They May Be Sniffing

While a natural dog behavior, excessive or forceful face sniffing should be discouraged.

Start by paying attention to contexts where your dog sniffs your face respectfully versus inappropriately. Identify triggers and patterns.

Redirect and Distract

Use treats, praise, and distraction to redirect your dog when they try sniffing your face at unsuitable times.

Avoid scolding or pushing them away, which can harm trust.

Be patient – it may take consistency and time before they understand boundaries.

Consider A Vet/ dog Trainer

If your dog obsessively or aggressively tries accessing your facial scents, consulting a vet or trainer may be needed.

Excessive sniffing could indicate anxiety, health issues, or neurological problems requiring assessment.

Teach Commands

You can also use the “leave it” command when your dog attempts unwanted face sniffing.

Reward them for obeying.

With time, they will learn sniffing only on your terms is allowed.

Walk Away

When your dog sniffs your face excessively despite training, briefly leave the room or area.

This teaches sniffing prompts your departure. As pack animals, your absence motivates them to change their behavior.


Overall, be understanding of your dog’s innate drive to sniff for information.

Allow plenty of consensual face access rather than suppressing natural instincts.

Stay calm when redirecting unwanted sniffing and keep training sessions positive.


The next time your dog shoves their snout into your face, resist the urge to push them away.

While an annoying behavior to humans, face sniffing is perfectly natural and important for dogs.

Your facial odors provide a wealth of social, emotional, and health information that allows your dog to interpret and connect with you.

It is a ritual that builds relationship bonds.

Rather than scolding your dog for following their natural instincts, be patient and use positive reinforcement to set boundaries around face sniffing.

With time and consistency, you can redirect unwanted sniffing while still allowing this sensory experience that means so much to your dog.
