A new study says dogs rely on their sight to understand the world, and the world they see looks vastly different from ours. The research, bolstered by some high-tech doggy goggles, is finally showing us how dogs actually see things. For years, we just assumed dogs were essentially colorblind, seeing the world in black and white. Our assumptions were incorrect.

Publishing their findings in Cognitive Science, researchers strapped some eye-tracking goggles on 11 dogs and let them go about their daily walks along a predetermined route. The eye-tracking device detected over 20,000 instances of dogs focusing their attention on specific things, which the researchers whittled down to exactly 11,698 after removing all the things the dogs looked at when they went into one of their sniffing trances.
