The Canine Rainbow and How Dogs See the World
How do we know how dogs see? Are they colorblind? Nearsighted? How do they perceive movement? Does their excellent sense of smell help dogs see? The first episode of Howtown from Adam Cole & Joss Fong is all about dog vision and is predictably fascinating.

I have been trying for years to find out about dog sound production - we know they _hear_ sounds in the ultrasonic range, but do they _make_ such sounds? I know sometimes my two dogs seem to communicate without barking or growling or anything else I can hear, so I am very curious
