The modern Beagle took shape in 1830s England from small packs of hare-hunting hounds, including the one kept by the Reverend Phillip Honeywood in Essex. It's a miniature foxhound in build, with a domed skull, long soft ears, brown eyes and a white-tipped tail, most often in tricolor. In the US it comes in two varieties, under 13 inches and 13 to 15 inches.
Many Beagles are merry and sociable, with a pack dog's love of company, but the nose runs the show. Expect baying, trash-can raids and a dog that follows a scent straight past you. In a city of older neighborhoods and backyards, a secure fence, a snug harness and food-based training go a long way. Beagles vary, and many adoptable ones are mixes, so each dog's own personality matters.
