Are blue eyed dogs more sensitive to the sun?
Scientifically, yes lighter colored eyes are more sensitive to bright lights and the sun because a lighter color iris allows more light to pass into the retina of the eye.

Why do police dogs wear goggles?

Are blue eyes more sensitive to dogs?
This kind of blue eye has nothing to do with the merle gene, white trim genes or the albino gene (which probably does not exist in dogs). These eyes are completely sound, though perhaps slightly light sensitive just as blue-eyed people are slightly more light-sensitive than those with brown eyes.
Are green eyes rare in dogs?
Similar to humans, the presence of green eyes in the canine world is a rare but striking sight. From Bulldogs to Beagles, almost all dog breeds sport eyes of varying shades of brown. This is down to the Merle gene which produces eumelanin—a brown pigment—in the iris.
