Through A Dog’s Eyes: How Your Pooch Sees The World

  • 03/02/2021
How-Pets-See-Your-Home.jpgEver wondered what the world looks like through your dog's eyes? Well, contrary to common misconceptions, pooch vision isn't limited to just black and white. Instead, as a recent article on HomeAdvisor points out, our furry friends can detect a range of colours, including blue, yellow, and grey.

Some experts think canines can also distinguish between red and green, although how they actually see these colours is up for debate. One theory suggests they see red as a dark brown colour, while another posits that red turns to black in a dog's eye.

Either way, one thing is for sure: doggy vision is more muted than a human's. Just imagine someone has turned the contrast down on the TV, and you'll start to get an idea of what this might look like.

Dogs see less colour than humans because they have fewer colour receptors - they've got two. We've got one extra. Also referred to as cones, colour receptors are cells in the retina that detect different wavelengths of light. They then decode the information into colours. In other words, fewer cones mean less data to process. Paint is a good comparison. You can make more hues by mixing three primary colours instead of two.

Despite their limited colour spectrum, dogs trump us when it comes to night vision. A larger pupil means dogs can see up to five times better than humans in dim light. And in terms of peripheral vision, dogs have always got us covered. Our four-legged companions have a 240-degree field of vision compared to our measly 180-degree limit. This probably explains why you can never walk into the kitchen without Fido thinking it's treat time.

The way dogs see the world is a result of natural evolution and selective breeding. But now that most dogs live a life of domestic bliss, can the way we arrange our home affect our pet's well-being? The answer is yes and no.

If you're the kind of person who likes bold and bright colours, then don't worry. Go as wild as you want. Dogs are indifferent to interior colour schemes. In fact, it pretty much looks all the same to them. But if you're thinking about freshening things up by rearranging the furniture, proceed with caution. Dogs thrive off familiarity and routine. So move one piece of furniture at a time to stop them feeling confused or disoriented.

As far as dogs are concerned, the way things smell is far more important than how they look.  Artificial aromas from air freshers and scented candles aren't so pleasant when you've got a super sense of smell. So go easy on them.

And always use scent-free sprays when cleaning a dog's favourite blanket or bed. Febreze it, and your pooch could have a very uncomfortable night's sleep. They might even try to sneak in with you instead. And as much as you love them, dog drool on the pillow might be just one paw across the line.
