Winston is a bulldog.   Some people say Bulldogs are mean looking, but like most bulldogs, Winston is a clown and his practiced smile belies his sense of humor.   His breed dates back to the 16th century but Winnie concentrates more on the future and his next meal.   Exceptionally smart, he prefers long walks to jogging up a sweat.   And Winston always tries to make a good nap on his back on the couch part of his regular routine.
