Dogs have powerful senses that enable them to do things that humans are unable to.
If you’ve ever walked your dog in the dark then you may have noticed that he reacts to things that you haven’t even noticed.
But, is this due to his great sense of smell or does he have an ability to see in the dark?
Dogs can see in low light conditions due to the design of their eyes which gives them an ability to detect motion and changes in light much better than humans.
Can dogs see in the dark better than humans?
Dogs are able to see in the dark much better than humans.
While humans have a narrowed field of vision in low light, dogs can see up to five times better than we can.
This is because their eyes have a higher concentration of rods, which allow them to see in the dark.
Dogs also have a layer of reflective cells called the tapetum lucidum that increases their vision at night, this is what makes a dog’s eyes glow at night time.
This layer reflects light back through the retina, increasing the amount of light that can be detected.
While your average human can only see about 5% of what’s available in total darkness, dogs can see as much as 20%.
Can dogs see perfectly in the dark?
No, dogs cannot see perfectly in the dark.
However, their vision is much better than ours in low light conditions.
This means that they are able to see things that we wouldn’t be able to see, such as a person or animal walking towards us in the dark.
Their improved vision also allows them to react faster to things that we may not even notice.
When combined with their great sense of smell dogs have the advantage over humans when it is dark.
Can house dogs see in the dark?
Yes, all dogs can see in the dark to some degree.
However, some breeds of dogs have better vision than others.
For example, working dogs such as Border Collies and German Shepherds have better eyesight than smaller breeds like Chihuahuas.
This is because they were bred for jobs that require excellent vision, such as herding sheep.
Dogs have a higher level of rod cells in their eyes which allows them to see better in the dark than humans.
This is why they are often used as service animals for the visually impaired and why they make such great pets for families that spend a lot of time outdoors.
So, the next time you’re out on a walk with your dog at night, don’t be afraid – know that they can see just fine.
