Head
The nostrils should be wide, large and black, with a well-defined line
between them. Any nose other than black is objectionable
and a brown or liver-colored nose shall disqualify. Lips--The chops or "flews" should
be thick, broad, pendant and very deep, completely overhanging the lower
jaw at each side. They join the underlip in front and almost or quite cover
the teeth, which should be scarcely noticeable when the mouth is closed.
Bite--Jaws--The jaws should be massive, very broad, square and "undershot," the
lower jaw projecting considerably in front of the upper jaw and turning
up. Teeth The teeth should be large and strong, with the canine teeth or
tusks wide apart, and the six small teeth in front, between the canines,
in an even, level row.
Neck, Topline,
Body
Neck -- The neck should be short, very thick, deep and strong and well
arched at the back. Topline -- There should be a slight fall in the back,
close behind
the shoulders (its lowest part), whence the spine should rise to the loins
(the top of which should be higher than the top of the shoulders), thence curving
again more suddenly to the tail, forming an arch (a very distinctive feature
of the breed), termed "roach back" or, more correctly, "wheel-back." Body--The
brisket and body should be very capacious, with full sides, well-rounded ribs
and very deep from the shoulders down to its lowest part, where it joins the
chest. It should be well let down between the shoulders and forelegs, giving
the dog a broad, low, short-legged appearance. Chest--The chest should be very
broad, deep and full. Underline--The body should be well ribbed up behind with
the belly tucked up and not rotund. Back and Loin--The back should be short
and strong, very broad at the shoulders and comparatively narrow at the loins.
Tail--The tail may be either straight or "screwed" (but never curved
or curly), and in any case must be short, hung low, with decided downward carriage,
thick root and fine tip. If straight, the tail should be cylindrical and of
uniform taper. If "screwed," the bends or kinks should be well defined,
and they may be abrupt and even knotty, but no portion of the member should
be elevated above the base or root. (continue)
