The beagle is a breed of small hound that is similar in appearance to the much larger foxhound. The beagle is a scent hound, developed primarily for hunting hare (beagling). Possessing a great sense of smell and superior tracking instincts, the beagle is the primary breed used as detection dogs for prohibited agricultural imports and foodstuffs in quarantine around the world. The beagle is intelligent. It is a popular pet due to its size, good temper, and a lack of inherited health problems. Beagles are used as sniffer dogs for termite detection in Australia, and have been mentioned as possible candidates for drug and explosive detection. Because of their gentle nature and unimposing build, they are also frequently used in pet therapy, visiting the sick and elderly in hospital. In June 2006, a trained Beagle assistance dog was credited with saving the life of its owner after using her owner's mobile phone to dial an emergency number.
