When the nose knows, it knows
Some dogs can smell dead bodies under water, where termites are hiding, and natural gas buried deep under dirt. They can even detect cancer that is too small to be detected by a doctor and can find lung cancer by sniffing a person's breath.
Who's got the smarts? And, who doesn't
The most intelligent dogs are reportedly the border collie and the poodle, while the least intelligent dogs are the Afghan hound and the Basenji.
