The Man's Best Friend Theme This Week

This week we're talking about our friends, the dogs. One of the sights we'll have a link to is a a daily mail on line piece that can help you see the way that dogs see. Dogs don't have the full color perception that humans do and also their vision is not as acute as ours. But even if dogs aren't as good we are at viewing things with vision, their sense of smell is out of this world compared to ours. And that has led to dogs being used, at least experimentally, to detect diseases.
