Apparently, dogs see UV light very well (which humans don't)
This results in some weird and wonderful visions!

How exactly true all this is I don't know. I guess scientists have come to those conclusions by noticing dogs see UV light more easily than humans, but it is interesting.

I don't know about all those "facts".....some seem a bit far fetched.

I do know that canines have special cells inside their eyes to help reflect light multiple times to increase their night vision.
I do know that canines have about 22 million plus smell receptors in their nose and roughly 40% of their brain is for smell.
I do know that canine hearing range is well beyond human hear range, roughly 2x.
I do know that canine are red/green color blind, but they do see color. This is why they lose a green toy in green grass.

It is interesting to debate those "facts" as cited in the article, but what is the information source???
