Dogs have a famously great sense of smell, but what makes their noses so much more powerful than ours? They're packing some sophisticated equipment inside that squishy schnozz.

--- How much more powerful is a dog’s sense of smell compared to a human?
According to one estimate, dogs are 10,000-100,000 times more sensitive to smell than humans. They have about 15 times more olfactory neurons that send signals about odors to the brain. The neurons in a dog’s nose are spread out over a much larger and more convoluted area allowing them more easily decipher specific chemicals in the air.
--- Why are dog noses wet?
Dog noses secrete mucus which traps odors in the air and on the ground. When a dog licks its nose, the tongue brings those odors into the mouth allowing it to sample those smells. Dogs mostly cool themselves by panting but the mucus on their noses and sweat from their paws cool through evaporation.
--- Why do dog nostrils have slits on the side?
Dogs sniff about five times per second. The slits on the sides allows exhaled air to vent towards the sides and back. That air moving towards the back of the dog creates a low air pressure region in front of it. Air from in front of the dog rushes in to fill that low pressure region. That allows the nose to actively bring odors in from in front and keeps the exhaled air from contaminating new samples.

they have such complex snoots but cant seem to find the treat i dropped on the ground 4 seconds ago
they're actually too excited to treat the information received from the nose, their brain is like "ok we are going to look for it with our eyes since we saw it 4 seconds ago"
instead, if you just make them smell the treat and then hide it (without letting them see it at any point) no matter how excited they are they will be more likely to look for it with their nose
Bruhhhhhh this had me dying!!! Haha
They find it yet?
Doggo noses are so cute
this made me giggle 😄
I can never say this enough, no channel on TH-cam is as underrated as yours.
Ah yes 800k+ subs is underrated
@@triscuit6516 yep
My channel...
@@poser7869 no your channel isnt underrated it just sucks :(
@@EarthIsFlat456 just a matter of what people like more facts channels there are like hundi of them who end up posting the same things more or less but gaming channels offer more a social reaction to their subd with live streaming and sub meet ups etc
I'm amazed that you guys are still managed to find tiny facts I never thought about. Dogs exhale air in a different direction so it won't disturb their next air sample! Through a cute little slit in their nose! WHAT???
This video would be hours long
Even we humans have this. But it is down between buttocks.
@@ahmedm5780 Time to see a doctor about your exhalation flatulence 12 times a minute.
Haha I just checked my dogs nose for that slit
Wow you must super duper smart.
The writer had a pun in each scent-tence...
Wow, the joke was dog-gone funny.
Fur-give me for that.
They were just hidden about for you to happen a-pun
I can’t BAYLEEF you made that on the spot
Ok I’ll LEAF now don’t PUN-ish me
@@sprinkleydonut8087 not funny
@@sprinkleydonut8087 you kinda milked it tbh
Doggo nose is also for boops
And mlems
Jiyū Maehara: Oh yes. An old dogger im sitting gets ”booped” all the time. He just stares at me like a questionmark 😂
Bop!
It's not called a Doggo nose. It's a Doggo Snoot.
Yeeee haha
we don't deserve this amount of quality for free.
No, we do.
PBS!
yeah we do. i aint sitting through ten 30 sec ads just to watch a 2 min vid
@@tommybro5313 maybe we dont
Except it's not for free.
God bless this channel and everyone who works on it.
Yes, Zeus is pleased.
Gandalf bless this channel and everyone who works on it.
Fun fact; wolves are not even close to as good with their noses as dogs. Basically by teaming up humans and dogs had the opportunity to specialize in different ways while having eachother as a safety net
I wonder if humans have lost some of our smell sensing abilities when we teamed up with dogs?
@@silverish9081 likely.
Whenever I come across a video about dogs I recall the intense grief I felt when I accidentally killed my dog in Minecraft
they had us in the first half, i'm not gonna lie
Recommend using a mod "friendly fire" to prevent accidentally killing your own pet.
I mean, dont everyone?
I Killed 3 tamed Dogs Because i Thought They were Bad Wolves When i First ever Played MineCraft... R.I.P. My Friends' dogs I Killed
Cause of Death: Misunderstandings
I miss little Biscuit
Dude you're everywhere
Yes! that's why every time I try to hide my cheese sticks, I always fail!
Well to be fair most cheese is pungent enough that even a human could track it down
YES my dogs could hear the wrapper being opened and the smell of the cheese being exposed to the air from across the house. Suddenly, you have big brown eyes looking up at you with the sweetest expression. So much for enjoying a whole stick of cheese yourself...
Not to sound like a creep but I have noticed your comments in many recently uploaded video today!! Coincidence??
@@ChrissehCat same with me and my toastie. I have to record it sometime, he basically wakes up from his sleep with his nose twitching and he kind of follows the scent before his eyes are fully open 😂😂😂
You can't imagine how much I love your videos :')
Samee
maybe do a deep look inside an ant colony? maybe even on the leafcutter ants and how they farm?
edit: lol nvm you already had such video
They did make a leaf cutter video a while ago. Though another ant colony video could be interesting
@@Ecotasia a video on how ants and termites evolved beside each other in a million year war would be neat
This is a good video about a pupper's snooter and how it boops.
yeah ikr
All those dog nose close ups are weirdly satisfying to watch.
i want to boop the noses.
You just sold me with that "Yes, she is" :)
that "yes she is" was so cute
Dogs scent can also remind them of traumatic events. For example, when we used to bring our dog on a car ride she would get super anxious when we drive by the veterinarian office. I guess she thought we were taking her in for a visit. Their scent is amazing.
Have you made a video on snakes? Like, shedding and movement,
I think that would be interesting
Nope- we haven't yet. Good suggestion!
Ya that may be more interesting
Important question: DID ANYONE BOOP THE SNOOT? anyway, really good animation. Also it's nice to see the cross section of the olfactory recess.
I booped the snoot.
@@raptorrex4973 *snout 😉
I love how wonderful the inside of the dog looked like all the anatomy and how amazing it looked props to ur editors! Also you I love ur voice❤️🔥
She protecc
She tracc
But most importantly...
She bring hiker bacc
Yes
I said "Yes she is!" In unison with you and it made my entire week.
Very nice! Great visualization overlays!
if I remember right, in comparison, if a humans sense of smell is as big as a post stamp, then a dogs is as big as a fotball court
Shining Star no, they only have 15x more sensory cells then us
But that doesn’t take tha quality of the cells in to Count
Wow!!! Dogs are really amazing. This channel really teaches you about everything. Learned many things on this channel, I'm so lucky that I've subscribed here.
"yes she is" 0:44
i pressed like, awh doggos x
She’s such a good girl 🥺✨💞
i've only met this dog this video but i love her already
Aw she's such a good doggy!!!
Beautifully made video, thanks so much!
I always like the vid before watching it! I just know that the video is GREAT!
I would advise against making a habit of that. You probably won't be disappointed here, but elsewhere, perhaps.
Thanks for reminding me.
And here is my dog, still sleeping all day ...and can't even sniff out her own food.
But she is everything to me...
She is a pug btw.
That explains a lot. Pugs are brachycephalic, like Bulldogs, Boxers, etc. They have breathing problems because of their very short snouts. They can also overheat, because their mouths don’t open as wide as, say, the German Shepherd in the video, so their panting is less efficient than a long nosed dog’s.
Sad. We need to either stop breeding pugs, or selectively breed them into something better. Pugs are suffering because they look cute.
Your videos are always so high quality. We don't deserve this knowledge you give us!! 😩😩
Yes you do!
High quality contents as always! Really love this channel. ❤
I can’t stop watching your videos they are so addicting ❤️
These visualizations are great! My favorite thing I learned is that the exhale goes out the side, I had wondered why their nostrils were shaped like that. So cool.
deep peeps is the best fandom name I have ever heard
This channel deserve 200M subs!!! Keep up the good work guys!!
Aww this is the best video you guys have posted yet! Keep doing what you do! My dog kinda looks like this one so if she's on the opposite side of the house and I grabbed a treat for her she comes running. Dogs truly are amazing so are cats! I wish us humans had that ability 😭
If the guy/gal who does the music on this channel doesn't have a Grammy I'll scream
Blessed be the doggo's snout !!!
You’re the only commenter who spelled it right. Everyone else is spelling it “snoot.”
This channel is beyond amazing, wish they’d teach things like this in school!
Very Informative - Thanks for posting this.
I. WANT. THAT. BOOP.
Doggo nose:GIVE. THAT. BOOP
me:MUST.....BOOP!!!!!!!!!!!
So... A Little Bit Of pepper May Cause the Dog to endlessly Sneeze?...hmm
Loved the visualizations! Great job :D
What an amazing channel.✌️
Nice work team Deep Look.
Why are there comments from 2 or 3 days ago?
Probably Patreon, if they have one.
If they uploaded it privately first and shared it with specific people then those people can comment before the video is uploaded publicly

experiments and research?
@@fachryhakiki Wait wait wait 😲 THEY CUT A DOGS NOSE OPEN 😲

Very interesting and informative video.
Thank u so much
I must boop the snoot
bruva Alfabusa?
*snout
I have a dog?
I like how they can tell time with their sense of smell, like learning and associating a certain scent concentration with when we come home.
Great video! Doggies are so intelligent and helpful. The nose knows.
NEED TO BOOP
