Beagle

The Beagle is a British breed of scent hound, similar in appearance to the much larger foxhound. It was bred primarily for hunting rabbit or hare, known as beagling. Its sense of smell and tracking instincts make it suitable for use as a detection dog for prohibited agricultural imports and foodstuffs in quarantine. It is commonly kept as a companion dog.
