MALE
Head - The chiseled head imparts to the Boxer a unique individual stamp.
Expression - Intelligent and alert
Eyes - Dark brown in color, not too small, too protruding or too deep-set. Their mood-mirroring character combined with the wrinkling of the forehead, gives the Boxer head its unique quality of expressiveness.
Ears - Set at the highest points of the sides of the skull, are cropped, cut rather long and tapering, raised when alert.
The beauty of the head depends upon harmonious proportion of muzzle to skull. The blunt muzzle is one-third the length of the head from the occiput to the tip of the nose, and two-thirds the width of the skull. the head should be clean, not showing deep wrinkles (wet). Wrinkles typically appear upon the forehead when ears are erect, and folds are always present from the lower edge of the stop running downward on both sides of the muzzle.
Substance - Sturdy with balanced musculature. Males larger boned than their female counterparts.
Female
Skull - The top of the skull is slightly arched, not rounded, flat nor noticeably broad, with the occiput not overly pronounced. The forehead shows a slight indentation between the eyes and forms a distinct stop with the topline of the muzzle. The cheeks should be relatively flat and not bulge (cheekiness), maintaining the clean lines of the skull, and should taper into the muzzle in a slight, graceful curve.
Muzzle- The muzzle, proportionately developed in length, width and depth, has a shape influenced first through the formation of both jawbones, second through the placement of the teeth, and third through the texturue of the lips. The top of the muzzle should not slant down (downfaced), nor should it be concave (dishfaced); however, the tip of the nose should lie slightly higher than the roof of the muzzle.
The nose should be broad and black
The upper jaw is broad where attached to the skull and maintains this breadth except for a very slight tapering to the front. The lips, which complete the formation of the muzzle, should meet evenly in front. The upper lip is thick and padded, filling out the frontal space created by the projection of the lower jaw, and laterally is supported by the canines of the lower jaw. Therefore, these canines must stand far apart and be of good length so that the front surface of the muzzle is broad and squarish and, when viewed from the side, shows moderate layback. The chin should be perceptible from the side as well as from the front.
