Have you ever wondered what your dog sees when he looks up at you, or at the treat in your hand?

Fascinating photos developed by a vet show how our puppies see the world compared to humans.

Color-blind dogs can only visualize yellow and blue, as evidenced by a series of photos of popular tourist hotspots, including the Peak District National Park, Brighton Pier and Durdle Door.

‘Dogs have dichromatic vision, which means they can only see in two colors; blue and yellow,” says Rhian Rochford, a veterinarian with the online company PocketVet.

‘While people see in three colors; blue, yellow and red. Instead of seeing red, a dog sees dark brown.

‘Green is seen as a beige color and purple as a blue shade.’

Brighton Pier appears to bulge out for your dog and can be up to eight times blurrier than a human’s view, as seen in the image to the right

A dog cannot visualize Durdle Door’s bright colors as shown in the image on the right because they only have two types of color-detecting photoreceptor cells in their eyes

Dogs still have a high quality of life despite their eyesight as they rely heavily on their other senses such as their smell which is 10,000 to 100,000 times more pungent than ours

At the back of the human eye are photoreceptors, which respond to light shining in, and those used to detect color are called “cones.”

The reason your pet’s vision is different is because they only have two types of cones while humans have three.

In addition, the photoreceptors used for movement and night vision are called ‘rods’.

Dogs’ retinas are heavy with rods, allowing them to see better in the dark and detect movement much better than humans.

As shown in the image of The Cotswolds on the right, dogs have four to eight times more blurred vision than humans, and also distinguish brightness half as well as humans.

Even without the color palette, there is plenty to see for dogs in the village of Portmeirion, North Wales, as can be seen from their vantage point in the image to the right

Dogs can only see yellow and blue, rather than the full spectrum of colors that humans can.  They see dark brown instead of red, beige instead of green, and blue instead of purple.

WHY DO DOGS VIEW DIFFERENT FROM PEOPLE?

At the back of the human eye are photoreceptors — cells that respond to light shining in — and the cells used to detect color are called “cones.”

Dogs see in different colors to us because they only have two types of cones, while humans have three.

The photoreceptors used for movement and night vision are called ‘rods’, and dogs’ retinas are heavy with rods, allowing them to see better in the dark and detect movement much better than humans.

Dogs’ eyes are also angled at 20 degrees, which increases their peripheral vision.

However, this also means that they can’t see things as 3D as humans, reducing their depth perception.

According to Ms. Rochford, our canine companions are also born with up to eight times more blurred vision than humans, and a reduced ability to perceive clarity.

She added: ‘Dogs have four to eight times more blurred vision than humans, they also distinguish brightness half as well as humans.

The eyes of “dogs” are angled at 20 degrees, which increases their peripheral vision.

“However, this also means they have less binocular vision — not seeing things as 3D — than humans, reducing their depth perception or ability to determine the distance between objects.”

But don’t feel like rushing to Specsavers for puppy-sized glasses as our pets still have a good quality of life despite their eyesight.

This is because they rely heavily on their other senses, such as their sense of smell which is 10,000 to 100,000 times sharper than ours, so they can still cope well if their eyesight deteriorates.

According to a survey by customer research firm TLF, 84 per cent of UK dog owners plan to stay with their pet in the future to show them the sights and smells of the UK.

Shannon Keary, of the dog-friendly holiday rental company Canine Cottages, who commissioned the photos, said: ‘As many Brits are taking their puppies on a staycation this year, we thought it would be interesting to see how dogs see the sights compared to how we do that. , and really understand what goes on in our dogs’ minds!

“While the images vary drastically, it’s exciting for dog owners to see what their pets are going through – and also encouraging to know that even without perfect vision, our dogs are still healthy and happy.”

Glenfinnan Viaduct is the famous railway line for the Hogwarts Express in the Harry Potter franchise, and Rhian Rochford magically showed us how our dogs would see the train (right)

Dartmoor National Park wouldn’t be quite as colorful for your dog as seen in the image to the right, but they would still enjoy sniffing with a nose up to 100,000 times sharper than ours

It turns out that dogs don’t need perfect vision to recognize their owners, as a study found that dogs can only identify their owners by their voice.

Researchers from Eotvos Lorand University in Hungary found that dogs are attached to their owner’s voice, which generates reward-related brain responses in the pup.

Amazingly, this brain activity is similar to that of a newborn baby listening to their mother, indicating that the dog-owner and baby-mother relationships are more similar than previously thought.

To find out, the researchers invited 28 dogs and their owners to play a classic hide-and-seek in the lab.

The owner hid behind one of the two shelters, while a stranger hid behind the other.

From their hiding place, both the owner and the stranger read out recipes in a neutral tone while the dog was given the task of choosing one from a distance.

The game had several rounds, with 14 different voices of strangers, some of which were more like the owner’s voice, and some more different.

To make sure smells weren’t helping the dogs, in the final two rounds, the researchers played the owner’s voice from where the stranger was hiding, and vice versa.

The results showed that dogs found their owners 82 percent of the time, even when the voices were switched.

According to the team, this suggests that dogs didn’t use their noses at the task, and instead could only recognize the voice.
