The Giant Schnauzer should resemble, as nearly as possible, in general appearance, a larger and more powerful version of the Standard Schnauzer, on the whole a bold and valiant figure of a dog. Robust, strongly built, nearly square in proportion of body length to height at withers, active, sturdy, and well muscled. Temperament which combines spirit and alertness with intelligence and reliability. Composed, watchful, courageous, easily trained, deeply loyal to family, playful, amiable in repose, and a commanding figure when aroused. The sound, reliable temperament, rugged build, and dense weather-resistant wiry coat make for one of the most useful, powerful, and enduring working breeds.
Strong, rectangular in appearance, and elongated; narrowing slightly from the ears to the eyes, and again from the eyes to the tip of the nose. The total length of the head is about one-half the length of the back (withers to set-on of tail). The head matches the sex and substance of the dog. The top line of the muzzle is parallel to the top line of the skull; there is a slight stop which is accentuated by the eyebrows.
Compact, substantial, short-coupled, and strong, with great power and agility. The height at the highest point of the withers equals the body length from breastbone to point of rump. The loin section is well developed, as short as possible for compact build.
The forequarters have flat, somewhat sloping shoulders and high withers. Forelegs are straight and vertical when viewed from all sides with strong pasterns and good bone. They are separated by a fairly deep brisket which precludes a pinched front. The elbows are set close to the body and point directly backwards. Chest - Medium in width, ribs well sprung but with no tendency toward a barrel chest; oval in cross section: deep through the brisket.
Hard, wiry, very dense; composed of a soft undercoat and a harsh outer coat which, when seen against the grain, stands slightly up off the back, lying neither smooth nor flat. Coarse hair on top of head; harsh beard and eyebrows, the Schnauzer hallmark.
The hindquarters are strongly muscled, in balance with the forequarters; upper thighs are slanting and well bent at the stifles, with the second thighs (tibiae) approximately parallel to an extension of the upper neckline. The legs from the hock joint to the feet are short, perpendicular to the ground while the dog is standing naturally, and from the rear parallel to each other. The hindquarters do not appear over-built or higher than the shoulders. Croup full and slightly rounded. Feet-Well-arched, compact and catlike, turning neither in nor out, with thick tough pads and dark nails. Dewclaws - Dewclaws, if any, on hind legs should be removed; on the forelegs, may be removed.
