A body not long but muscular, allowing liberty, with a deep chest and well-sprung ribs, strong neck, straight front and especially strong loins. Males should be masculine in appearance and deportment without unwarranted aggressiveness; bitches feminine without weakness of structure or apparent softness of temperament. Bitches may be slightly longer in back than males. They should both give the appearance of being capable of great endurance but be free from coarseness. Because of the depth of chest required, the legs should be moderately long.
