An ancient scent hound from England, bred since the 1500s for hunting rabbits and hares in packs, the Beagle pairs an unstoppable nose with a sunny disposition. Friendly with everyone — children, strangers, other dogs — and remarkably affordable to feed and maintain for a medium dog. The trade-offs are loud baying that carries for miles, food obsession that leads to obesity, and an independent streak that makes off-leash recall a lifelong project.
