Spotted a bulldog on a train back to Nijmegen, after a short trip to San Francisco and Santa Cruz (first time to SF bay area= wow [shot film, let you know when its available]). She was an older bully (graying muzzle) with a huge underbite. She may have actually been a mix with a boxer because she did not have a flat face with a fat wrinkle over the nose, but had a more elongated snout and the legs seemed to be longer, though I didn't see her stand. She did have the bulldog temperment though, shrugging off incidental kicks from her lay under the train seat.
