I was so interested by
this because I'd never seen this
before. Well, that was a lie. I've seen cats chase around laser
pointers, but I was curious why Harley had chased the dot. My other dogs, Nani
and Stitch had never done that before, actually that day, Dylan had tried
to flash the laser towards them and they couldn't have cared less about it.
Also, I grew up thinking that dogs were colorblind, so I wondered why
Harley was so intrigued by something she could barley see. I was as curious about
this just as Harley was about the dot. So I had to do some research on this phenomenon. I was surprised to learn that dogs and cats are
not colorblind, however, the colors that they see are
less distinct than the colors humans see. According to Science
Made Fun, humans have three cones in their eyes; red, blue, and green. These cones send the images to our brains that help us distinguish colors. Live Science says that dogs are either missing a third cone or it just doesn't work. The image below is the color spectrum of a dog and a human.
I'm not going to lie, this kind of blew my mind. I mean I went through my entire life thinking dogs only saw in black and white, so I never questioned anything. Harley could see the dot after all. Science Made Fun also mentions that scientists test this theory by rewarding dogs with treats if they pick a certain color. It's important for us to know how smart our dogs actually are. Some people believe that dogs are nothing but animals who poop on the floor and retrieve a stick or ball if thrown at them, but dogs are so much more than a "mutt." Dogs are brave, kindhearted, and so intelligent and if we treat them otherwise, what does that make us? Dogs are man's best friend and we should give them a little credit.
Science Made Fun left a link to a cool little Youtube video about colorblindness. It's a quick test to see if you could be colorblind. If you would like to check it out here's the link: https://www.youtube.com/watch?v=oADLENgvo4I

I'm glad you included how they conduct the test. I was wondering how they would know. Great blog
ReplyDeleteWow I really did think that dogs were color blind. I have been thinking this ever since I was little. Now when a person says a dog is color blind I can show them this blog and let them discover this amazing information.
ReplyDeleteI didn't know that dogs weren't color blind because I also have grew up with people telling me that. It's fascinating how this actually works though and I love the way you address it in your blog! Good job!
