The most common myth about a dog's eye sight is that they are completely color blind.
Dogs can in fact see colors, just not as well as us humans.
A dog vision does not recognize figures by their detail and texture like us humans, but instead by their shape and different form.
A dog's sight is no where near as good as our sight as humans.
It is a thought out myth by how well dogs hunt and capture their pray but they have just become good at what they can work with.
Dogs see different in color values different from us humans as well.
To give the common example dog trainers sometimes define, a dog will not see a difference in a red ball on green grass.
The colors will blend in, but a different color ball such a pearl or peach color will be seen.
It all kind of just depends on the color differences.
But on the other side of us seeing better colors than canines, they see movement a much better practice.
Such things like animals or rodents on the move, dogs are very likely to see whereas us humans are more likely to just look at the still position objects.
On the flip side, canines can see incredible at night.
To compare how us humans see compared to dogs, it is a huge differential fraction.
Do not under estimate how well your canine can see at night.
If you ever wonder how dogs run at such high speeds at night, this can answer it.
