The modern Beagle took shape in 1830s England from a pack of small hare hounds, and it still looks like a miniature foxhound: domed skull, long soft ears, brown eyes and a white-tipped tail. In the US, Beagles come in two varieties, up to 13 inches and 13 to 15 inches, usually weighing 18 to 30 pounds. Many shelter Beagles are mixes, so size and looks vary.
Most Beagles are merry and sociable, with a pack dog's love of company. The nose rules everything, though: expect scent-tracking, baying and trash-can raids. In St. Louis that means a secure yard or a leash on every outing, and a plan for the neighbors on the other side of the fence or wall. Daily exercise and food-based training help, and weekly brushing handles moderate shedding.
