question about a dog's vision

[Billy Costigan]

I've heard numerous times that dogs see in black and white and can see a couple colors. How in the heck did someone find out what a dog can see? I mean if a dog can't talk or write something down how do scientist know what they see? This is a serious question. Can someone please tell me exactly how they claim to know what a dog sees through a dog's eyes when they are human?

Probably a dog like Scooby told a scientist.

Yes, dogs are unable to speak or write English. They are not completely dumb and have the ability to react to different stimuli. If you think about it for a second, it really isn't too hard to think of multiple possible experiments to find out. Many high school kids set out to prove dog colorblindness for their Science Fair Experiment.

Dogs that eat live squirrels can see with the squirrel eyes too.

That begs the question, do squirrels see in color?

Billy I can confirm they love peanut butter.

They see red really well.

The reason I say this, a dog can lick his schlong in complete darkness and not miss one square inch

How can you be sure of this in complete darkness?

Night vision? But I don't think I really wanna know. Also can't blind squirrels scratch nuts and what not...
