General Appearance

 Size, Proportion, Substance

Height--Adult males 23 to 25 inches; females 21½ to 23½ inches at the withers. Proper balance and quality in the individual should be of primary importance since there is no size disqualification.
Proportion--The body in profile is of square proportion in that a horizontal line from the front of the forechest to the rear projection of the upper thigh should equal the length of a vertical line dropped from the top of the withers to the ground.
Substance--Sturdy with balanced musculature.  Males larger boned than females.

The beauty of the head depends upon harmonious proportion of muzzle to skull. The blunt muzzle is 1/3 the length of the head from the occiput to the tip of the nose, and 2/3rds 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 are always present from the lower edge of the stop running downward on both sides of the muzzle.
Expression--Intelligent and alert.
Eyes--Dark brown  in color, frontally placed, generous, 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.  Third eyelids preferably have pigmented rims.
Ears--Set at the highest points of the sides of the skull, the ears  are customarily cropped, cut rather long and tapering, and raised when alert.  If uncropped, the ears should be of moderate size, thin, lying flat and close to the cheeks in repose, but falling forward with a definite crease when alert.
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 as they 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 texture 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 root of the muzzle. The nose should be broad and black.  
Bite--The Boxer bite is undershot, the lower jaw protruding beyond the upper and curving slightly upward.  The incisor teeth of the lower jaw are in a straight line, with the canines preferably up front in the same line to give the jaw the greatest possible width. The upper line of incisors is slightly convex with the corner upper incisors fitting snugly back of the lower canine teeth on each side.  Neither the teeth nor the tongue should ever show when the mouth is closed.
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.  Any suggestion of an overlip obscuring the chin should be penalized.

Neck--Round, of ample length, muscular and clean without excessive hanging skin(dewlap). The neck has a distinctly marked nape with an elegant arch blending smoothly into the withers.
Back and Topline--The back is short, straight, muscular, firm, and smooth.  The topline is slightly sloping when the Boxer is at attention, leveling out when in motion.
Body--The chest is of fair width, and the forechest well defined and visible from the side. The brisket is deep, reaching down to the elbows; the depth of the body at the lowest point of the brisket equals half the height of the dog at the withers. The ribs, extending far to the rear, are well arched but not barrel shaped. The loins are short and muscular. The lower stomach line is slightly tucked up, blending into a graceful curve to the rear. The croup is slightly sloped, flat and broad.  The pelvis is long, and in females especially  broad. Tail is set high, docked and carried upward.  An undocked tail should be severely penalized.

The shoulders are long and sloping, close-lying, and not excessively covered with muscle (loaded). The upper arm is long, approaching a right angle to the shoulder blade. The elbows should not press too closely to the chest wall nor stand off visibly from it. The forelegs are long, straight and firmly muscled, and when viewed from the front, stand parallel to each other. The pastern is strong and distinct, slightly slanting, but standing almost perpendicular to the ground. The dewclaws may be removed. Feet should be compact, turning neither in nor out, with well arched toes.

The hindquarters are strongly muscled with angulation in balance with that of the forequarters. The thighs are broad and curved, the breech musculature hard and strongly developed. Upper and lower thigh are long. The legs are well angulated at the stifle, neither too steep nor over angulated,  with clearly defined, well "let down" hock joints. Viewed from behind, the hind legs should be straight with hock joints leaning neither in nor out. From the side, the leg below the hock (metatarsus) should be almost perpendicular to the ground, with a slight slope to the rear permissible. The metatarsus should be short, clean and strong. The Boxer has no rear dewclaws.

Short, shiny, lying smooth and tight to the body.

The colors are fawn and brindle. Fawn shades vary from light tan to mahogany. The brindle ranges from sparse, but clearly defined black stripes on a fawn background, to such a heavy concentration of black striping that the essential fawn background color barely, although clearly, shows through (which may create the appearance of "reverse brindling"). White markings, if present,  should be of such distribution as to enhance the dog's appearance, but may not exceed one-third of the entire coat. They are not desirable on the flanks or on the back of the torso proper.  On the face, white may replace part of the otherwise essential black mask and may extend in an upward path between the eyes, but it must not be excessive, so as to detract from true Boxer expression.  The absence of white markings, the so-called "plain" fawn or brindle, is perfectly acceptable, and should not be penalized in any consideration of color.
DISQUALIFICATIONS--Boxers that are any color other than fawn or brindle.  Boxers with a total of white markings exceeding one-third of the entire coat.

Viewed from the side, proper front and rear angulation is manifested in a smoothly efficient, level-backed, ground covering stride with powerful drive emanating from a freely operating rear. Although the front legs do not contribute impelling power, adequate "reach" should be evident to prevent interference, overlap or "sidewinding"(crabbing). Viewed from the front, the shoulders should remain trim and the elbows not flare out. The legs are parallel until gaiting narrows the track in proportion to increasing speed, then the legs come in under the body but should never cross. The line from the shoulder down through the leg should remain straight although not necessarily perpendicular to the ground. Viewed from the rear, a Boxer's rump should not roll. The hind feet should dig in and track relatively true with the front. Again, as speed increases, the normally broad rear track will become narrower.  The Boxer's gait should always appear smooth and powerful, never stilted or inefficient.
