Did You Know...
... THAT DOGS CAN SEE COLORS?
It is widely held, though no one is sure why, that dogs do not see in color. In fact, dogs have trouble distinguishing green, yellow, and red but blue and purple can be seen vividly. As predators, dogs need their vision most to distinguish motion and follow prey through the brush in a hot pursuit. Most of the dog's world is defined by scent, though, as their sense of smell is a good 1000 times stronger than ours.
