We talked for a minute but she kept getting distracted focusing towards a car (her car) that was several feet away. There was a dog in the car that would pop up and bark if anyone walked pass the car which is normal. I asked her why she kept looking out and she told me her dog gets crazy when a black person walks pass the car.  I found it humorous and never considered the fact that dogs are suppose to be colorblind. I would've asked her to explain that with no hesitation but I was floored.  I pointed out that the dog barked at everyone that came pass the car. She said that he barked the loudest and jumped the seats when the black couple walked past.  I am not trying to make this a racist topic or a debate, and I am unsure about the color blind theory. I think most dogs in cars bark as protecting their owners property. Kodak barks and growls at any male, female, beast or child that are 10 to 100feet away just claiming territory. Maybe it's just me, but I ended the conversation with you better go check on your dog. Maybe he thinks he's about to get Jacked, & I went in the store. |
Your friend is partially correct, hundreds of tests showed dogs could not distinguish between colors, but it was found out the tests were done wrong. Because of a dogs intensive sense of smell the, dogs were noticing odor cues and not sight cues. When tests were done ruling out odor as one of the components that differentiated between the objects, it was found that dogs could distinguish different colors.
The dog sight experiments are used as a classic example in experimental psychology as to why an experiment has to be set up in such a way as to rule out any other variables that could produce the result. Unfortunately, many people just remember the first tests so this is why there is some confusion.
Even among humans there is a great deal of difference on how we see colors. Woman on average can see many more differences in shades of color than men.
