Simulation shows what dogs see and hear when they look at us and it’s blown people’s minds

An incredible simulation has given an indication of how a dog might actually perceive their human.

It's a question which has dogged anyone who has had a dog in their life - how does your beloved pooch actually see and hear you?

Dogs have very different sensory perceptions to humans.

For starters, their eyes - if dogs were humans, they would be wearing glasses, with their vision generally near-sighted.

A dog would have to be 20 feet away to see an object as well as a human could from 75 feet away, and mutts can't see the colors red, orange and green. They perceive blues and yellows best.

It's not all bad news for dogs in the eyesight department though. The extra rods in their retinas and larger pupils mean they're better at seeing in the dark, and they're also better at seeing moving objects than we are (mailmen they want to chase, sticks being thrown).

They have 10 to 20 times better motion sensitivity than humans, according to PetMD.

Their hearing is also super different to a human's. They can hear sounds that are twice as high-pitched as we can, hearing up to 45,000Hz while the best we can manage is 20,000Hz.

In real terms, this means they can hear things like insects and rodents that we can't, and also the hum of electric lights and the quartz crystals in digital clocks.

They can also hear sounds that are around four times quieter than humans, but can't hear lower-pitched sounds.

They also have a slower perception of time than we do because of their high metabolism - one hour for us feels like 75 minutes for them.

BBC Earth documentary Secret Life of Dogs revealed: "Dog's eyes process what they see more quickly than we do. It's almost like they see in slow motion."

So how does this all look in real terms? What would it be like to see the world through your dog's eyes?

YouTube creator Benn Jordan set out to create a simulation of how a dog might perceive things.

In the video, the camera shows a dog's point of view from the ground, with the colors more intense and objects blurrier than we see them.

Jordan explains in the video that dogs perceive time as being about 33 percent slower than we do.

So when he played back the video, the sounds including his voice were lower and the movements slower.

Many people took to the comments on social media to share their reaction to the incredible clip.

One joked that it was funny that humans appear 'slow' to dogs, writing: "Crazy to think they’re still our best friends when we are so slow to them lol."

Another shared that they had an inkling that dogs might see us as a bit slower, because of how quickly they can move compared to us.

They wrote: "Wow. I always thought that, just due to size difference and movement speeds, that dogs would perceive us as slow lumbering giants. But I had no idea how true that was."

Meanwhile, someone else wrote that it was amazing to them that dogs see in slow motion, saying: "In my wildest dreams I never imagined that dogs perceive the world in slow motion."

Of course, this doesn't quite give the full picture as the most important sense for a dog is the sense of smell.

They have 60 times more scent glands in their nose than we do, while the part of their brain that controls smell is 40 times larger.

So while their vision is less clear than ours, their sense of smell is so sensitive that dogs can even be trained to smell cancer.
