This is probably the most fashionable pet dog now in vogue. His character is full of dignity and consummate pride, and disgust for anything menial or common. (?? - curator) His head is massive, broad, wide and ﬂat between the ears and eyes. The eyes should be large, dark, prominent, round and lustrous. “Stop” deep. Ears heart-shaped, drooping and well feathered. Muzzle very short, broad and wrinkled. He has a heavy—fronted body and light hind quarters, and the great coat on the frill and neck give him a lion-like appearance. The coat should be long, straight and ﬂat, with dense under-coat and well feathered on thighs, legs, tail and toes.
