Did you know??
*The basenji, an African wolf dog, is the only dog that cannot bark
*A dog can hear sounds 250 yards away that most people cannot hear beyond 25 yards. The human ear can detect sound waves vibrating at frequencies up to 20,000 times a second. But dogs can hear sound waves that vibrate at frequencies of more than 30,000 times a second
*Dogs cannot see as well as humans and are considered color blind. A dog sees objects first by their movement, second by their brightness, and third by their shape
*Dogs are able to see much better in dim light than humans are. This is due to the tapetum lucidum, a light-reflecting layer behind the retina. Because it functions like a mirror, it also accounts for the strange shine or glow in a dog's eyes at night
*The first living creature to orbit the earth was a dog. Named Laika ("Barker" in Russian), she blasted off aboard the Soviet Union's Sputnik 2 on November 3, 1957. With no way to bring her back to earth, she became the first creature to give her life for the exploration of space
*The fastest dog, the Greyhound, can reach speeds of up to 41.7 miles per hour. The breed was known to exist in ancient Egypt as many as 6,000 years ago
