30 Dog Nose Facts Your Dog Wants You to Know

1. Wet noses help capture scent.

Interestingly, whether a dog's nose is wet or not has little to do with health. The myth of dry nose indicating a sick dog has been debunked. With the myth set aside, those wet noses play a primary role in detecting smell. Having a wet nose helps dogs capture tiny scent particles which increases a dog's ability to detect the smells. Just as a wet cloth picks up dust better than a dry one, explains Stanley Coren in an article for Psychology Today.

2. Crusty noses and noses with ulcers or bumps need veterinary attention.

While a dry nose doesn't necessarily mean your dog is sick, keep an eye for crusty noses or noses with ulcers. In older dogs, crusty noses may be a sign of nasal hyperkeratosis, a condition that causes a distinctive thickening of the skin of the dog's nose making it appear crusty. Discoid lupus, on the other hand, is an autoimmune disorder known for causing unsightly ulcerations on the dog's nose. Dogs may also develop cancers in the nose and allergies.

3. Dog noses can be employed in different sniffing methods.

Dog noses can be used for tracking or air scenting. In tracking, dogs tend to carry their heads low so to detect the scent of broken vegetation, while in air scenting, dogs will instead carry their heads high considering that they are after the lighter, more volatile compounds left behind by humans.

4. Dog noses can sniff many types of cancer.

According to UC Davis Health System, researchers have established that dogs are so far capable of recognizing melanomas as well as bladder, lung, breast and ovarian cancers. Who knows if one day we'll find furry coats along with lab coats in some future cancer diagnostic settings!

5. That little indentation in the nose has a purpose.

That little indentation, known as "philtrum," found in the middle of the bottom part of the nose and at the top of your dog's upper lip, is thought to carry moisture from the mouth to the rhinarium—the moist surface area of your dog's nose.

6. The Lagotto Romagnolo dog breed has a nose for truffles.

In 1985, the use of pigs for finding truffles has been prohibited because of the substantial damage these animals have caused to truffles. This vacancy has led to the use of the Lagotto Romagnolo in Italy for hunting down truffles.

7. Dogs have a vomeronasal organ.

On top of having a powerful nose, dogs come also equipped with a special organ known as the vomeronasal organ or the Jacobson organ. This organ acts as second nose, powering up a dog's sniffing capabilities. The vomeronasal organ simply consists of a patch of sensory cells found within the nasal cavity just above the roof of the mouth. It is meant for detecting pheromones. Pheromones are hormone-like, behavior-altering agents that are released by dogs for the purpose of other dogs detecting them.

8. Dogs have a bump on the roof of their mouth that helps them analyze odors.

This little bump is known as the "incisive papilla" and communicates with the dog's vomeronasal organ which is responsible for detecting pheromones.

9. Teeth chattering helps send scent to the incisive papilla.

Dogs may sniff a spot, then flick their tongue against this little bump or they may chatter their teeth. When they do so, they send scent molecules towards their incisive papilla so that they reach the vomeronasal organ and dogs can better analyze the smell.

10. Dogs may use sniffing as a calming signal.

The term "calming signal" was coined by Norwegian dog trainer Turid Rugaas to describe special signals dogs use to communicate with each other. Sniffing the ground is one of them. It is often seen when dogs see another dog approaching and want to signal no threat.

11. Dogs use their tongues in place of a tissue to blow their noses.

Unlike humans, dogs can't go grab a Kleenex and blow their nose." Dogs with chronic nasal discharge tend to adopt a casual "drip and lick" approach rather than deliberate attempts to blow," says veterinarian Dr. Mark Rondeau.

12. Dog nose prints are as unique as human fingerprints.

According to a study, taking nose prints in dogs is actually quite a fairly easy process. All that's needed is to dry the nose with a lint swab, impregnate the leather of the nose with China ink and a nose print is then printed on a white cardboard. Voila!

13. Dogs use nose touching to gather info.

Cats may touch noses, but so do many dogs. According to a study, nose touches in dogs may reveal information that go beyond saying hello, perhaps more like something along the terms of "Hey, have you encountered any good treats around here?"

14. Some dogs have a Dudley nose.

A Dudley noses is a flesh-colored nose that is often means for disqualification in the show ring for several breeds. A dark, black nose is usually preferred from a health standpoint because the pigment protects against the sun. The term Dudley nose derives from bulldogs bred from a part of Black Country in Worcestershire, UK.

15. To dogs, smell is ever-changing.

Ever wondered how dogs never grow bored of sniffing the same spots day after day? Here's some food for thought: "Each departure from the house brings a new scene, one never visited. Each day, each hour, wears a new smellscape. There is no such thing as “fresh air” to a dog. Air is rich: an olfactory tangle that the dog’s nose will diligently unknot," explains Alexandra Horowitz in the book: "Being a Dog: Following the Dog Into a World of Smell."

16. A dog's nose has special structures that amplify smells.

These special structures are called turbinates and they consist of intricate mazes made of bone. Their purpose is to control how air moves through the dog's nose providing an increased surface area, and therefore, greater reception of smell. A dog's long nasal cavity helps accommodate these turbinates.

17. Foxtails are a threat to dog noses.

Foxtails release seeds that may get sniffed up into dog noses, causing sneezing, pawing at the nose and even nose bleeds. Affected dogs require veterinary attention to remove the lodged foxtail from the nose.

18. The furless skin surface of the dog's nose is called rhinarium.

It can also be called planum nasale, but some dog owners simply refer to it as nose or snout, while breeders may prefer to call it "nose leather. "

19. Dogs have slits at the side of their noses for a reason.

While the interior part of the dog's nostrils is meant to take in air, the exterior slits found on both sides of the dog's nostrils allow air to escape every time the dog exhales. The exhaled air flows out of those slits creating a swirl of air which lifts more particles of odor off the sniffed surfaces allowing them to be suctioned for further investigation.

20. Dogs are capable of moving their nostrils independently, one at a time.

According to a study conducted by Siniscalchi, M., et al, dogs tend to use first their right nostril for smelling things considered non-threatening (and then right afterward switch to using their left nostril), while they exclusively use the right nostril when sniffing things associated with threat.

21. Dogs don't fear the scent of rattlesnakes.

According to a study, the lack of a right nostril preference while sniffing rattlesnake-associated odours, suggests an absence of fear. This may explain the high rates of rattlesnake envenomation in dogs.

22. Flews help collect scent.

Those pendulous, droopy lips often seen in bloodhounds and other dogs that are used for scent help trap smells as these dogs are sniffing with their heads low to the ground. This allows those precious scent molecules to reach their destination: to the almighty nose and beyond!

23. A puppy's nose can interfere with potty training.

If you fail to clean up properly soiled areas using the right products, this may come back and bite you. Patricia McConnell in her book "Way to go! How to housetrain a dog of any age " claims: Any scent left behind says: "this is your bathroom" just as those universal bathroom signs found scattered around in any public place. Make sure to use an enzyme-base cleaner to clean up your puppy's accidents to prevent this "bathroom sign" effect!

24. Dogs prefer to urine mark on vertical items.

When dogs urine mark, they are leaving their scent on certain surfaces for the purpose of providing other dogs with relevant information, sort of like a business card. Just as you would put your business card at eye level on a bulletin board, dogs will mark on vertical objects so to leave their scent "at nose height for other dogs." On top of this, the scent of urine is known to last longer on a vertical surface compared to an horizontal one. Yes, now you know why dogs are so attracted to peeing on your car's tires!

25. Dogs may be able to tell the passage of time with their noses.

Alexandra Horowitz in the fabulous book: Being a Dog, Following the Dog Into a World of Smell claims, "As each day wears a new smell, its hours mark changes in odors that your dog can notice. Dogs smell time. The past is underfoot; the odors of yesterday have come to rest on the ground."

It is, therefore, possible that dogs may predict their owner's arrival from a long day at work from how long the owner's scent concentration lingers since he leaves the house. Researchers suggest that after dog owners leave the house, their smell lingers for some time. There's a possibility that the scent decays slowly over the day, and around a certain time, dogs associate a specific amount of scent with when the owner should be unlocking the door.

Rare Dog Breeds with Split, Double Noses

26. There are some dog breeds equipped with a distinctive split "double" nose.

Examples include the Pachon Navarro and the rare Catalburun of Turkey. The double-nosed Andean tiger hound is another one but this one most likely descends from the Pachon Navarro. The double nose is simply a nose with nostrils that are split by a band of skin.

27. Dogs can detect scents at concentrations of one part per trillion (ppt).

For sake of an example, that the one drop of a liquid in 20 Olympic-size (2500 ft3) swimming pools!

28. Dogs detect individual scents.

You may just smell soup when you come home and mom is cooking dinner, while your dog smells carrots, celery, potatoes, parsley and all the other minute components of that soup!

29. Dog noses are lined up with cilia.

A dog's nose is equipped with special sensors that are meant to detect foreign particles, basically things that shouldn't be there. When these sensors detect foreign particles in the nose such as dust, pollen or debris, the cilia, which are special broom-like structures lining the dog's nose and lungs, spring into action, readily triggering a sneeze. The sneeze helps sweep the irritants out of the dog's lungs and out of the dog's body. Achooooo!

30. Putting your dog's nose to work increases your dog's optimism!

According to a study, allowing dogs to spend more time using their noses through fun nosework activities makes them more optimistic. By allowing dogs more "foraging" time, their welfare is therefore improved.

Dog noses are fascinating! So many interesting facts and I am sure there are many more we still need to discover.

Lorelei Cohen from Canada on July 18, 2019:

Well I do indeed now know everything about a dog's nose that I could ever want to know and a little more. You have truly done your homework on this article. Amazing.

Adrienne Farricelli (author) on April 05, 2019:

Shepards, there is so much being discovered lately on those dog noses. These dog nose facts are just a few, there are many more!

It's super cool that you did tracking with your GSD, they are an amazing breed!

Adrienne Farricelli (author) on April 05, 2019:

Michelle, I know I had to look twice when I first heard about these weird dog breeds with double noses or split noses.

Sam Shepards from Europe on April 03, 2019:

I started with ow, I know that and that. Then I went oh really? Serious?

Fascinating article, coming from someone who did tracking training with German Shepherds when I was between 11 and 18 years old.

Michelle on April 03, 2019:

Wow, the split nose thing is kind of weird, I'd love to see one. Really interesting read. thanks

Heidi Thorne from Chicago Area on April 01, 2019:

Absolutely fascinating! Some of our dogs have been active sniffers (like our current boy dog). He has his snoot to the ground a lot of the time we're out on walks. And then he'll occasionally do an alert head up sniff, nostrils flaring to take it all in. He's so intent on it, we have to stop. Though we don't know his exact breed mix, he definitely has some strong tracking breed in him.

Thanks for this wonderfully informative article!

Adrienne Farricelli (author) on March 31, 2019:

Yes, dogs' smelling abilities are quite impressive! I can't stop looking at my dog sniffing and exploring his whereabouts and wondering what it must feel like. Gotta love those dog noses, especially when they come to such great use to humanity.

Larry Slawson from North Carolina on March 31, 2019:

Very cool. Had no idea that dogs could actually detect certain cancers too! Thank you for sharing!

30 Interesting Christmas Facts to Impress Your Friends and Family

Mistletoe means something very unromantic in German.

When you're searching for non-controversial conversation starters for around the dinner table or anytime that one family member wants to start something (we've all got 'em), these Christmas facts will come to your rescue. They also make great trivia fodder for a fun holiday game night, even if yours are via video call this year. We all probably already know there's a lot more to Christmas than finding and then unwrapping gifts (see our gift ideas for 2020!), donning Christmas sweaters and finding Christmas decorations that make the house look like Santa's workshop. It’s an age-old celebration with centuries of tradition and meaning behind virtually every aspect of the holiday that will have even the holly jolliest of us saying, "Huh! I never knew that!"

From the religious observations you may already look forward to every year to pagan origins and some facts that are just entertaining, we guarantee you'll learn something from this list. Take a breather from the frenetic pace of the holiday season check this list twice. Maybe you’ll even get inspired to write some of them in your family’s annual Christmas letter or card or give your social media posts some flare.

While Christmas celebrates the birth of Jesus Christ, there is no mention of December 25 in the Bible. Most historians actually posit that Jesus was born in the spring. And his birthday itself didn't become the official holiday until the third century. Some historian believe the date was actually chosen because it coincided with the pagan festival of Saturnalia, which honored the agricultural god Saturn with celebrating and gift-giving.

The tradition of Christmas trees goes all the way back to ancient Egyptians and Romans, who marked the winter solstice with evergreens as a reminder that spring would return. So if you decorate with a green tree, wreaths or evergreen garland, you're throwing it back – way back.

You might want to brew a cup o' tea when trimming your tree this year to pay homage to its origins. When Prince Albert of Germany introduced a tree to his new wife, Queen Victoria of England, it really took off across the pond. A drawing of the couple in front of a Christmas tree appeared in Illustrated London News in 1848 and as we say, the idea went viral.

You probably already knew that the idea of Santa Claus came from St. Nicholas, but the real saint wasn't a bearded man who wore a red suit. That all came much later. According to legend, the fourth-century Christian bishop gave away his abundant inheritance to help the needy and rescued women from servitude. His name was Sinter Klaas in Dutch, which later morphed into Santa Claus. The rest of the trappings followed.

Before Coca-Cola got in on it, Santa used to look a lot less jolly — even spooky. It wasn't until 1931, when the beverage company hired an illustrator named Haddon Sundblom for magazine ads that we got the jolly old elf. Now, kids won't get nightmares when they dream of Christmas eve.

According to legend, we hang stockings by the chimney with care thanks to a poor man who didn't have enough money for his three daughters' dowries. Generous old St. Nick (remember, that's his trademark!) dropped a bag of gold down their chimney one night, where the girls had hung their stockings to dry. That's where the gold ended up, and how the tradition began.

Rudolph the Red-Nosed Reindeer first appeared in 1939 when the Montgomery Ward department store asked one of its copywriters to create a Christmas story the store could give away as a promotional gimmick. The store had been giving away coloring books for years, and decided to make its own to save money.

The Christmas wreath originated as a symbol of Christ. The holly represents the crown of thorns Jesus wore at his crucifixion, and the red berries symbolize the blood he shed. So when you see a wreath this season, you'll remember the reason for the season.

Turns out, we were originally dashing through the snow for an entirely different holiday. James Lord Pierpont wrote a song called "One Horse Open Sleigh" for his church's Thanksgiving concert. Then in 1857, the song was re-published under the title it still holds today, and it eventually became one of the most popular Christmas songs.

This prank almost went too far. Nine days before Christmas in 1965, the two astronauts aboard Gemini 6 sent an odd report to Mission Control that they saw an "unidentified flying object" about to enter Earth's atmosphere, traveling in the polar orbit from north to south. They interrupted the tense report with the sound of “Jingle Bells,” as Wally Schirra played a small harmonica accompanied by Tom Stafford on a handful of small sleigh bells they had smuggled aboard.

By the time the Puritans settled in Boston, celebrating Christmas had been outlawed. From 1659–1681, anyone caught making merry would face a fine for celebrating. After the Revolutionary War, the day was so unimportant that Congress even held their first session on December 25, 1789. Christmas wasn't proclaimed a federal holiday for almost another century, proving that the Grinch's notorious hatred of the holiday was alive and well long before he was.

The Jamestown settlers created the first American batch of eggnog, although it may not have tasted quite the way we know and love today. The word nog comes from the word grog or any drink made with rum. So technically, an early nog didn't require the rich, milky base we now ladle out of grandma's cut-crystal punch bowl.

If you've ever watched Clark Griswold decorate his house in Christmas Vacation, that probably doesn't come as much of a surprise. In fact, the Consumer Product Safety Commission estimates that 14,700 people visit hospital emergency rooms each November and December from holiday-related decorating accidents. So please, be careful when you're decking your halls.

Every year, letters to Santa Claus flood post offices across the world, forcing parent to find a way to answer them or explain to the kiddos why their letter got, um, lost in the mail. Cementing their reputation as one of the nicest countries around, some big-hearted Canadian Post Office workers started writing back. As the program took off, they set up a special postal code for Santa as part of a Santa Letter-Writing Program initiative: HOH OHO.

For the love of Christmas, don't forget to water your tree. Dried-out Christmas trees spark about a hundred fires each year, cause an average of 10 deaths, and result in $15.7 million in property damage, the Consumer Product Safety Commission reports. Not only will an errant spark ruin your holiday, it can put both you and responding firefighters in danger.

Between Thanksgiving and New Year's Day last year, the U.S. Postal Service delivered an estimated 910 million packages — in addition to almost 15 billion pieces of mail. That includes gifts for faraway loved ones, cards, letters to Santa and those dreaded credit card bills after we put our holiday purchases on plastic (oops).

Think "Xmas" is a newly nefarious attempt to take Christ out of Christmas? Think again. According to From Adam's Apple to Xmas: An Essential Vocabulary Guide for the Politically Correct, "Christianity" was spelled "Xianity" as far back as 1100. X, or Chi, in Greek is the first letter of "Christ" and served as a symbolic stand-in. In 1551, the holiday was called "Xtemmas" but eventually shortened to "Xmas." In reality, Xmas is just as Christian as the longer version.

It may feel like Christmas is everywhere you turn from October right on through New Year's, and those decorations hit stores earlier every year. That's partially because most Americans really do jingle bell rock their way right through the season: over 90 percent of us. Not all of those celebrate it as a religious holiday, though.

If church seems a little sparse on Christmas Eve, there may be a reason for that. The Pew Research Center found that fewer people think of Christmas as a religious holiday these days. Only 51% of people who celebrate attend church on Christmas. It didn't say what percentage of those only go on Christmas and Easter.

According to the National Retail Federation's 2017 data, consumers spend an average of $967.13 for the holidays, although individual spending can vary widely. In 2018, total retail sales in November and December hit a staggering $717.45 billion.

The holiday flora is an ancient symbol of fertility and virility — and the Druids considered it an aphrodisiac. So keep that in mind next time someone jokes about meeting you under the mistletoe. You might want to know what you're getting yourself into.

The name itself even has a meaning that might not inspire as many warm fuzzies, however. Mistle thrush birds eat the plant's berries, digest the seeds, and then the droppings eventually grow into new plants. So, the Germanic word for mistletoe literally means "dung on a twig." Pucker up!

Some families cook up a turkey for Christmas dinner, others go for ham, and still more go rogue and stick a leg of lamb or another protein in the oven. Google searches for "ham" and "turkey" both spike during the month of December, according to Google Trends data. Despite the popularity of both festive entrees, spiral-cut ham remains the more popular choice for a Christmas table. The jury's still out on whether people prefer ham or turkey sandwiches the day after, though.

The National Confectioners Association says a choirmaster originally gave the candies to young children to keep them quiet during long church services. Grandmas who still dole out sweets during droning sermons, you've got history on your side. But it wasn't until a German-Swedish immigrant decorated his tree with candy canes in 1847 that they became popular as a Christmas candy.

The first tree at Rockefeller Center probably looked more like Charlie Brown's than the resplendent one today. Construction workers at the site first placed a small, undecorated tree while working there in 1931. Two years later, another tree appeared in its place, this time with lights. It grew and grew from there. Nowadays, the giant Rockefeller Center tree bears more than 25,000 twinkling lights and is visited by millions of selfie-takers each season.

You may know Washington Irving best for The Legend of Sleepy Hollow and his headless horseman, but he wrote a lot about St. Nicholas, too. In fact, he bestowed eight tiny reindeer on the big man. He loved Santa Claus so much that in 1835, he helped found the Saint Nicholas Society of the City of New York, serving as its secretary until 1841.

Londoners and visitors probably know the iconic spruce that stretches to the sky in Trafalgar Square each year, but few realize where it comes from. Every year since 1947, the people of Norway have gifted the tree to the people of London. They donate the tree in gratitude for Britain's support for Norway during World War II. Now that's what we call goodwill toward men.

During World War II, The United States Playing Card Company joined forces with American and British intelligence agencies to create a very special deck of cards. They gave them out as Christmas gifts that also helped allied prisoners of war escape from German POW camps. Individual cards peeled apart when moistened, to reveal maps of escape routes. Sometimes truth really is stranger than fiction.

Unless you cut it yourself, your "fresh" Christmas tree probably spent weeks out of the ground before it made it to your local retailer. And there's likely no hiking into the woods to get it, either: 98% of American trees today grow on farms, mostly in California, Oregon, Michigan, Washington, Wisconsin, Pennsylvania and North Carolina, the country's top Christmas tree-producing states.

We fart

Let's start with the obvious. Women do fart, even though our grandmothers swore that wasn't the case. But the facts don't lie. Everyone does, despite what your boyfriend or little brother thinks. Women fart just as much as men, passing gas an average of 10-20 times per day, according to Dr. Purna Kashyap, gastroenterologist at the Mayo Clinic in Rochester, Minn. A TED-Ed video he helped create explains how passing gas is actually a sign of healthy gut function. Things like beans, oats, soy, and dairy can cause you to be more gassy than usual. Now, if you believe your excessive flatulence is affecting your day-to-day life, you may need to change your diet, or see a doctor to make sure it's not something more serious.
