Our dog is always freaking out as long as one of us has COVID. First time a few years ago he screamed as soon as he lost sight of my mildly sick girlfriend. He doesn't really care about other colds.
I vaguely recall reading somewhere that their sense of smell is like 100,000 times the strength of ours, plus they’ve got a whole area of their brain devoted just to processing odors. Their scent tracking is on a level humans can’t even dream of, we’re just along for the ride!
Not only that, but their sense of smell is stereoscopic! Or I guess maybe sono-scopic makes more sense, but just how when we hear a sound we can vaguely hear what direction and how far away it is, it’s the same for their smell
What?! That’s wild, I can’t even wrap my head around how that would work. Like, it makes sense when you say it, but I can’t even imagine what it would be like to experience.
Lol no i mean like you can tell if it's someone directly next to you, or if it wafts over from across the room (like if a dog farted on the couch and hit you 10 seconds later)
If I heard the dog fart, I could tell from the sound. If the dog is the only other one in the room, I can usually tell if it was me or it. But there’s no way I could tell from just the scent alone.
There was a murder in my country some years ago and corpse sniffing dogs on boats found the body even though it had been weighted down and was on the bottom of the ocean
It's impressive yes, but they're not smelling "through" the water as such, that's impossible, as the nose is obviously just a "receiver". Everything they smelled to track that ring were particles that dissolved into the water and then evaporated into the air.
My good friend, none of that changes anything about what I've said. To smell something, particles have to reach the nose of the creature smelling it. That's just how it is and how it HAS to be according to physics.
You might also be conflating a dog smelling something that is in the water with a dog's ability to smell while he himself is under water. However, the same mechanism applies, except that in this instance, the particles don't need to evaporate into the air, they just dissolve into the water, which are then picked up by the dog's nose.
Smell is always just particles getting to your nose. In that regard a dog can ”smell through water” since the particles move through it to its nose. To have the nose under water and smell I think sharks are better than dogs because they can breathe in water. However, it is still particles moving through particles to your nose - regardless of particles. The boundary we put between air and water in this sense is just a way to categorize different molecules and their attributes- and what is left is semantics.
The distinction is moving water. Crossing a pond, yeah no dice. Following a stream, esp if you have some time for the water to move away, different story. They’ll still be able to track the scent, but the scent will have moved down stream, so it is effective at throwing them off your track. Of course a dog handler would know this, and you’re gambling they won’t find the point where you exit the stream (and leave a fresh scent trail). Still, it’s not completely ineffective.
Water can be quite hard for search dogs. Water tends to act like a magnet. It will suck in all the other scents around as well. That can make it very hard for the dog to distinguish between the other scents.
Fun fact, I did some SAR training a couple weeks ago, they picked up on a 41 day old scent trail of a missing person before. Its incredible what dogs can do.
I used to encourage people to hide toys and treats from my bloodhound as a game. People would always try zigzagging and backtracking and rubbing the scent in other places before hiding it thinking that she would follow it. Except the dog would completely ignore all false trails and just go straight to the hiding spot everytime! It's amazing!
u/faithhopecarnage, there weren't enough votes to determine the quality of your post...
The fate of your post is in the hands of the most savage animals of all now, the mods.
Dogs have been shown to be able to track a fingerprint on a glass slide that was left exposed to the elements for a week. Water doesn't mean shit
yeah fr, they can even be trained to smell certain types of cancer. Dogs are amazing

We sort of have that. If someone in a room farts, you can generally tell which direction it came from and how far away it is based on smell lol
I don’t know anyone with this ability at all. Maybe you have dog dna.

Tbf, we have 11 billion or so synapses for our senses. 10 billion are for sight. Different animals, different primary senses

Quite impressive!!! Both the dog and your confidence!!
Well done on THAT training! He IS Superdog Saul!!
How in the what
Their sense of smell is insane.
And yeah, they can even smell things under water.
Can't imagine how they see (or smell) the world.
It's impressive yes, but they're not smelling "through" the water as such, that's impossible, as the nose is obviously just a "receiver". Everything they smelled to track that ring were particles that dissolved into the water and then evaporated into the air.
They can smell things that are under water.
A quick Google should sort that out for you.
Yes, in the way that I just explained to you.
They can smell things at the bottom of a lake. Things that weren't placed there recently.
They train what's known as cadaver dogs. And drug dogs to do it.

You're being unnecessarily pedantic dude. I can't smell things in a kitchen. The particles have to waft over to my nose. Its the same thing.
If it was unnecessary I wouldn't have had to repeat myself 3 times.

You are both right. The end.
Pedantic.
My dog loves scent games!
I have read that water actually makes the scent easier for the dog. The old movies where they crossed the water to get away were wrong

That's incredible, dogs are amazing
To be fair, usually its moving water there.

"what do you mean you lost it,, hang on give me a minute,, ZOOM"
I’m equally impressed that doggo did the full lie down indicator despite meaning submerging full tummy in what must be a cold puddle!
Haha that was my reaction too. Poor fella
Border collies are the best and smartest and my favorite dog and yes, he is playing a cool game you go baby!!!
That's genius
The fact that dogs do not need to breathe to smell is a hell of a feature I am glad I don’t have.
To never not smell everything at every moment would be maddening.
Scent trailing on your scent, I wonder if Saul would find it with another person scent. Great job Saul.
That is unbelievable !
Well that’s how genius roll … good doggie.
If only Smegol had Saul…
Dogs know everything on the dinner table better than you do with your eyes.
I feel so bad he chose to throw it in the puddle meaning the dog would have to lie in it 😭
Aston! Good dog!!
There must be a lot of “ noise” in their brains!
Poor wet belly
Wow, amazing
Amazing
omg!! Incredible!
Poor buddy had to lay in the cold ass water to signal. Awesome dog
Lol he can track it throgh anything actually!
superrrrrdog!
As a human, god dozed off while building my nose. Its clogged all the time
Next video should be a search at a beach
How can he do this????😱
Afriggingstonishing!
The dog deserves more than a like
I’m confused how he let the dog know what smell to look for
