Here's something I found really interesting. It's about the colors dogs see compared to what we see.

Lol.

Humans are believed to have three different cone types, a trichromat, while dogs have two, a dichromat. Each cone contains a photopigment that is maximally sensitive to a separate wavelength of light. These photopigments are what makes color vision possible. A human's three cone types are maximally sensitive at 445 nm, 535 nm, and 570 nm respectively. The canine cones are maximally sensitive at 429 nm and 555 nm.

Again please, but in English.:confused: :p

LOL, I thought it was a little over my head, I'm glad there were pictures. :D But I thought it was interesting, I was never sure if dogs can see colors, but they can, to a point.
