I'm always amazed at the incredible sensitivity of a dog's nose, aren't you? I've heard a Bloodhound's nose is 100 times as keen as a human's nose, and a German Shepherd's 40-50 times
No wonder they save so many lives by tracking missing persons or felons and by sniffing out bombs and drugs
Now in recent years, I've heard about training puppies still another use of their great natural talents – cancer detection!
