The Dog Nose Secrets Most Pet Parents Never Notice

Your dog’s nose isn’t just cute, it’s doing things you probably don’t even realize. From tracking invisible scents to sensing weather changes, that little snoot is working overtime.

What facts should I know about my dog’s nose?

Your dog’s nose can smell between 40,000 – 100,000 scents (humans can only smell 10,000)
A wet nose aids in trapping scent particles and making it easier to smell
Dogs have between 100 -300 million olfactory receptors compared to only 5-6 million in humans
Much like a human fingerprint, each dog nose print is unique (In fact, some microchip databases ask for a nose print. Also, some vets take nose prints as a keepsake when a dog crosses the rainbow bridge)
It’s a myth that a warm nose always means a sick dog
Dogs smell different scents with each nostril, much like you see different views with each of your eyes.
A dog’s nose contains sweat glands and helps to regulate body temperature
When a dog licks their nose, it helps to keep their nose moist, clean, and healthy
A dog’s nose is built to pick up scents even up to nearly 100′ underwater
Dog’s can smell a scent that is 5-14 days old
A dog’s nose can pick up scents that are as much as 40′ underground
Trained dogs can pick up scents that are 130 miles away

Note: Some dog breeds, like bloodhounds and beagles, are great for scent work. They smell the scent particles of lost people or even human remains after disasters. These breeds are often considered the best scent dogs.

Cracked or bleeding skin of the nose
Persistent dryness that doesn’t improve over time
Excessive discharge with yellow, green, or blood coming from the nose
Crusty build-up and dry nose
Lumps or bumps on or around the nose
Swelling or sores on the nose
Color changes (like white, pale color, pink patches on a usually dark nose)
Sensitive to touching the nose (especially sudden change in sensitivity)

Note: I had a cat years ago, whose bright pink nose would always turn ghost white whenever she was experiencing an illness of some sort. It was her way of saying, “I’m sick.”

When Should I call My Vet About My Dog’s Nose?

You will want to call your vet if your pup’s nose does any of the following:

Bleeding that won’t stop (a little bleeding may be okay. For example, a scratch or drop might be okay)
A thick and often colored discharge, like green, yellow, pink, or red mucus
Deep cracks or open sores
A sudden change in nose color, like my kitty would do
Your dog shows sensitivity to their nose being touched by flinching, turning his/her head, barking, or growling
Excessive licking of the nose
Pawing at the nose
Coughing, sneezing, lethargy, loss of appetite, or sudden change in behavior

What Are The Most Common Causes of Dog Nose Issues?

Weather – Cold or dry air, as well as too much sun, can make your pup’s nose dry, cracked, or sensitive from a sunburn

Allergies – Food or environmental triggers (Henry’s nose will get more runny if he sticks it into sagebrush)

Dehydration – If your pup isn’t drinking enough water, his nose can get dry. Henry drinks a lot more water with his water fountain. His nose will get dry if he hasn’t drunk enough during the day.

Hyperkeratosis – This is a condition that causes excess skin to build up and lead to a crusty nose.

Infections – An infection, regardless of whether bacterial, fungal, or viral, can change nasal health

Foxtails or debris – This can happen when your dog sniffs a foxtail or debris. Remember, your dog’s nose is generally wet, and items can stick to it like a magnet. I’m often surprised by what I will see stuck to Henry’s nose. I’ve seen everything from feathers, leaves, and dirt.

Autoimmune conditions – Health issues like lupus can change your dog’s nose health. Your vet will be able to diagnose and give you proper care instructions.

What Can I Do At Home To Ensure My Dog’s Nose Is Healthy?

Thankfully, it doesn’t take much effort to care for your dog’s nose. There are simple home remedies, DIY care solutions, and even easy store-bought options.

At-home care:

Wipe gently with a soft, damp cloth to remove dirt.
Keep fresh water available at all times. If your dog doesn’t drink as much water as you’d like, try a water fountain. It truly does encourage Henry to drink more.
Use a humidifier, which can be very valuable in dry climates. Just like the dry air can give you a nosebleed or allergies, the same is true for your pup. A humidifier can be a great idea for you and your pup.
Apply a dog-safe balm to your pup’s nose when your dog’s nose looks dry
Provide shade and limit sun exposure. This can be especially important for light-colored noses. You can even use a DIY dog safe sunscreen like this one from Aner Adventures.

DIY home solutions:

Coconut oil – Only apply a very, very small amount to your pup’s nose. It will moisturize and soothe, while not hurting your pup when it’s licked.
Shea butter – A pure, unscented, and dog-safe shea butter acts much like coconut oil. Again, apply a very, very small amount. You can always apply more if needed.
Olive oil – Can be very soothing for crusty, dry noses. But again, start with a small amount.

Store-bought options:

Dog-safe nose balms or butters
Sunscreen made for dogs, which is especially important for pale or pink noses
Moisturizing wipes for quick cleanups. I use these often for Henry since he has a tendency to stick his nose into the dirt to smell. He also gets a very dirty nose when he digs.

Here’s what you’ll want to do and look for daily to keep your pup healthy and your vet bills low.

Inspect your dog’s nose when brushing your pup for any unhealthy signs
Give your dog lots of water. Or get a water fountain to entice your pup to drink more.
Use a dog-safe sunscreen to protect your pup from a sunburn (even in winter)
Always have a dog-safe moisturizer on hand and use it as needed.
Check to make sure there is no obstruction in your dog’s nose, like a foxtail, dirt, or sticker
Call your vet if something looks or doesn’t feel right. It’s always best to err on the side of being safer rather than live in regret.

How can I save money with proper dog nose care?

You may never consider that your dog’s nose needs attention until there’s an issue. But when you watch for signs daily and care for your pup’s sniffer daily, you can avoid pricey vet bills. Consider the following for a moment.

Issue	Estimated Cost
Emergency vet	$100 – 5,000
Obstruction in the nose	$200 – 3,000
Nose cancer	$5,000 – 12,000
Healthy dog nose	PRICELESS!!!!

Boop that healthy dog nose!

I know a healthy dog nose may never occur to you until your pup has an issue. For Henry, I’m always watching if nose for the first signs that he doesn’t feel well and acting accordingly. Often, I think a furry friend’s nose is a barometer of health. It blinks or blares as there’s a health issue in the works. Act quickly, and it’s often easy to nip the issue in the bud, or maybe that’s the nose.
