Note the general outline of the dog, the "terrier " head with a fair length of muzzle.  Also note the coat texture - hard and straight.

These are two of the early Bailey (English) dogs of the early 30's.  Again note the longish muzzles and the hard straight hair coats.  These dogs do not have a "puggy" or so called "oriental" expression, but are distinctly Terrier in head type

Le and Phema, gifts of the Dalai Lama to the Suydham cuttings in the 40's.  Again you can see the terrier expression.  Also note the ear set and the very straight forefaces, with a large prominent nose leather.
