The beagle is a breed of small hound that is similar in appearance to the much larger foxhound. Beagles have a strong, medium-length neck (which is long enough for them to easily bend to the ground to pick up a scent), with little folding in the skin but some evidence of a dewlap; a broad chest narrowing to a tapered abdomen and waist and a long, slightly curved tail (known as the 'stern') tipped with white. Beagles are the dog breed most often used in animal testing, due to their size and passive nature. In the United States, as many as 65,000 beagles are used every year for medical, cosmetic, beauty, and other chemical tests. They are purpose bred and live their lives in cages undergoing experiments.
