The English Springer Spaniel is a sweet-faced, lovable bird dog of great energy, stamina, and brains. Sport hunters cherish the duality of working Springers: handsome, mannerly pets during the week, and trusty hunting buddies on weekends. Built for long days in the field, English Springer Spaniels are tough, muscular hunters standing 19 to 20 inches at the shoulder and weighing between 40 and 50 pounds.
