Why Does My Dog Sniff My Eyes? Understanding Canine Behavior

As a dog owner, you might have noticed your furry companion occasionally coming up to you and taking a gentle whiff of your eyes. It’s a puzzling behavior but not as strange as it might seem. The world of dogs is governed largely by their sense of smell. They use their noses to communicate, gather information, and interpret their surroundings. This article dives into why your dog might be so fascinated with the scent around your eyes.

1. The Power of a Dog’s Nose

It’s important to recognize their incredible olfactory ability to understand why dogs sniff eyes or anything. A dog’s sense of smell is estimated to be 10,000 to 100,000 times more sensitive than ours. They have up to 300 million olfactory receptors in their noses, compared to the mere 6 million we humans have. This heightened sense allows them to pick up on scents and chemical changes that are imperceptible to us.

2. Gathering Information About Your Health and Emotions

Your body secretes different chemicals and pheromones based on your emotions and health. Stress, for instance, can produce a particular scent. When dogs sniff your eyes, they might pick up on these tiny chemical changes. Tears, for instance, contain various chemicals that can hint at your emotional state, like whether you’ve been crying or are feeling stressed.

3. Bonding and Affection

Sniffing is also a way for dogs to bond. Just as humans might hug or kiss to show affection, dogs use their noses to get close and personal. Your dog might try to show closeness and create a deeper bond by sniffing your eyes. Their unique way of saying, “I care about you.”

4. Eyes as a Source of Unique Scent

Everyone has a unique scent, and different body parts can give off different odors. The area around the eyes might have a distinct smell due to tears, sweat, or even the oils from our skin. This smell might be intriguing or reassuring for dogs, helping them identify their beloved human.

5. Curiosity and Exploration

Sometimes, a dog’s actions are driven by sheer curiosity. The world is a tapestry of scents waiting to be explored by them. If your dog hasn’t sniffed your eyes before, or if you’ve used a new eye product, they might be trying to understand this new scent profile.

6. Seeking Comfort and Security

Dogs often find comfort in familiar scents. If they’re feeling anxious or uncertain, they might seek out the familiar smells of their owners. Your scent, especially around the face where they often receive affection, can provide reassurance and comfort.

Tips for Dog Owners:

  • Monitor their behavior: While occasional sniffing is normal, excessive or obsessive behavior might indicate underlying issues. Always consult with a veterinarian if you’re concerned about any behavioral changes.
  • Maintain hygiene: Clean your face and eye area to prevent infections or irritations, especially if your dog is a frequent sniffer.
  • Be gentle: If you wish to discourage your dog from sniffing your eyes, gently redirect them or use positive reinforcement training techniques. Never scold them harshly, as it might foster anxiety or fear.

Frequently Asked Questions (FAQs)

1. Why does my dog sniff my eyes?

Dogs have an extraordinary sense of smell, vastly superior to humans. They use this keen sense to understand their environment and gather information about the beings around them. Like other parts of your body, your eyes produce natural secretions and odors. When your dog sniffs your eyes, they might pick up on your scent or any changes in it. It can also be their way of understanding your emotional state, as some believe dogs can detect changes in our body chemistry that reflect our emotions.

2. Is it safe for a dog to sniff my eyes?

While it’s natural for dogs to be curious and want to sniff various parts of our bodies, letting them get too close to your eyes can be potentially unsafe. There’s a risk of bacterial transfer from the dog’s nose to your eye, which might lead to infections. Additionally, a sudden movement could inadvertently cause injury. While a brief sniff is likely harmless, it’s always best to gently redirect your dog and discourage behaviors that might risk injury or discomfort.

3. How can I discourage my dog from sniffing my eyes?

Consistency is key if you want to discourage your dog from sniffing your eyes. Every time your dog moves in to sniff your eyes, gently redirect them by guiding their head away or offering a distraction such as a toy or treat. Over time, your dog will learn that sniffing your eyes doesn’t lead to any reward. Combining a verbal cue like “no” or “enough” with redirection can further reinforce your desired behavior. Additionally, training your dog to recognize personal boundaries can be helpful in these situations.


In the grand scheme of canine behaviors, sniffing your eyes is a relatively benign and often affectionate gesture. By tapping into their unparalleled sense of smell, dogs try to understand us better, bond with us, and navigate their world. Next time your dog gets up close and personal, remember they’re just their curious, loving selves.
