An ancient breed, the Beagle is a scent hound, used for sniffing out rabbits and hares. Its ancestors were brought to England by William the Conqueror. Unfortunately, due to their placid nature Beagles used to be often used in animal testing. Fortunately for the easy-going Beagle, these days they are more likely to be a family pet. Butch the Beagle held the Guinness World Record for oldest dog, dying in 2003 aged 28 (196 in human years). Notorious Beagles include one we have known ? Dee, a dog with a mission ? and the most famous Beagle of all, Snoopy from the Peanuts cartoon.
