Dog vision, explained

Howtown - 2024-05-30

Apps claim to show you the colors dogs see – but where does that information come from?

WELCOME TO HOWTOWN! Our small but mighty team of two (Joss Fong and Adam Cole) digs into the evidence behind commonly held facts and claims in the news.

What other questions do you have about realities your pets experience?

@sailorkisser - 2024-05-30

I've heard that dogs can smell emotions from several places but never got an explanation of how. How are emotions measured quantitatively so we know dogs can smell them? Do we produce chemicals/pheromones for emotions that release into the air that we could measure with a device? Can other humans detect them?

@digressor - 2024-05-30

Do dogs wagging their tails really indicate their emotions?

Howtown, Big If True (Cleo), Johnny Harris, Search Party, etc. all excellent. All great story telling and informative.

09:18 Have you ever seen those movies with dogs reuniting with owners after a long time ? did you notice that when the dogs SEE their owner they dont recognize them , but after they SMELL him , they imediatly recognize him !

@wolfywolfhowl - 2025-09-08

I would like to see how a dog reacts after not seeing his owner after a long time, and someone else enters the picture wearing the clothes of the dogs owner, how would the dog be, confused, tripping, is the reaction the same.

@ToScale - 2024-06-07

Fantastic video. Shout out to the shot at :45... that's some serious motion control(?) / After Effects mastery. There are likely many hours behind those few seconds, and your viewers deeply appreciate it.

@isacami25 - 2024-06-14

i love that the representation for the smells that the dog is processing is also done through color, because that's the only way we can process it

I’m an Explosives Detection K9 Handler, and I’m really glad you brought up how we can’t understand how their olfactory senses factor into their vision!

We have a saying called the hamburger effect, where a human smells a hamburger and generalizes it, a dog smells and distinguishes the meat, bun, lettuce, tomato etc

@PlayNowWorkLater - 2024-05-30

I remember learning about this in university, but that explanation didn’t even come close to this summary. I wish I had this back in my university days. Probably would have got that question right on the exam. Future generations will have THIS to view to help them understand a very interesting topic. I really look forward to future videos of whatever topics you decide to explore and explain how we actually know something. Great channel idea.

@kavyavijay4953 - 2024-06-03

I love how German works. ‘Umwelt’ is the word for environment and is made up of ‘Um’ (around) and ‘Welt’ (world), so it’s the world around you

@brinta2868 - 2025-04-29

@kavyavijay4953
In other words, pretty much the same as in English.
environ = Old French for 'to surround'
Environment = that which surrounds you

@Csakbetksszmok - 2025-06-06

Hungarian is also full of such composed words : )

@mike_et_saika - 2025-07-11

@@brinta2868 English and German have the same indogermanic ancestry, so the basic mechanics on how words are put together are quite similar.

But to be fair, "Umwelt" is a bit broad and unspecific. "Umweltbewusstsein" would better fit the context of this video. Bewusstsein = awareness. Or "Umweltwahrnehmung". Wahrnehmung = perception.

I also speak Lithuanian, where my parents are from. Lithuanian is almost proto-indogermanic, very archaic language. Aplika = Ap- (circular-) and linka (bent around). A circle bent around (f.e. an individual).

@คี-ซะมะ - 2025-02-04

0:44 I'm jealous of all of you who could see a number. Also, the bit previous to this comparing human vision and dog vision - they were almost identical for me, just that in the dog vision one of the colours (red, I think) was darker.

@คี-ซะมะ - 2025-02-04

4:57 ... Again, just no difference for me other than there's less shine on the blue.

@Vim-Wolf - 2025-07-13

Something that made me laugh. In our puppy classes they had pictures on the wall "This is what you see" and "This is what your dog sees" and with my colour blindness they looked EXACTLY THE SAME 🤣 So I see exactly the colours my dog sees, but without the benefit of nasal enhancement. 👃

It's really strange that almost every human hears "dogs are color blind" and thinks this means that they don't see any colors, but nobody would ever think that about a color-blind person.

@Padoinky - 2025-08-05

An even more basic question is how do we know that when two people are looking at the same thing, that they’re actually seeing the same thing in the same manner (size, structure format, texture, color, etc)?
