The Appenzell Mountain Dog presents a striking, well-balanced appearance that reflects its Swiss mountain heritage and working capabilities. This medium to large breed exhibits a slightly longer than tall rectangular build, with males standing approximately 20 to 23 inches at the shoulder and females measuring 19 to 21 inches. The overall silhouette conveys strength and agility without appearing heavy or cumbersome, perfectly suited for navigating mountainous terrain and performing demanding farm work.
The head is proportionate to the body with a relatively flat skull that forms a slight but defined stop. The muzzle is strong and tapers slightly toward the nose, which is always black regardless of coat color. Eyes are small to medium-sized, almond-shaped, and typically dark brown, expressing an alert and lively character that reflects the breed's attentive nature. The expression should convey intelligence and confidence without appearing aggressive or timid. Ears are triangular, set high on the skull, and hang close to the cheeks with slightly rounded tips. When alert, the ears lift at the base and turn forward, creating an attentive appearance that exemplifies the breed's watchful temperament.
The neck is strong and muscular, flowing smoothly into well-laid shoulders that allow for efficient movement. The body displays a firm, level topline with a broad, deep chest that extends to the elbow, providing ample room for heart and lung capacity necessary for sustained work. The ribs are well-sprung, creating a robust torso, while the underline shows a moderate tuck-up. The back is straight and firm, leading to a slightly sloping croup. Legs are straight and sturdy with well-developed muscles, demonstrating the strength required for herding and pulling work. The front legs are perpendicular to the ground with strong pasterns, while rear legs show proper angulation at the stifle and hock joints.
Feet are compact and round with well-arched toes and thick pads, designed for navigating rocky alpine terrain. The tail is set high and carried in a tight curl over the back, forming one of the breed's most distinctive characteristics. This natural curl should be tight enough that the tail tip touches the back or side of the body. The tail remains curled even during rest, though it may hang slightly lower when the dog is very relaxed.
The coat consists of a close-lying, harsh-textured topcoat with a dense undercoat available in black or brown. The characteristic tri-color pattern includes a base color of either black or havana brown (a rich brown shade), with symmetrical white and rust markings. White markings typically appear as a blaze running from the top of the head down through the muzzle, a white chest patch extending to the throat, white on all four feet, and white on the tail tip. Rust or tan markings appear above the eyes forming distinctive eyebrows, on the cheeks, on the legs between the white and black or brown areas, and on either side of the chest patch. These markings should follow a symmetrical pattern, though perfect symmetry is less important than overall balance and correct placement.
The breed standard identifies several disqualifications including blue eyes, incorrect color patterns, aggressive or overly shy temperament, absence of proper tri-color markings, and structural faults that impair movement or working ability. Faults that detract from the breed's working capability receive particular emphasis, as the Appenzell Mountain Dog's form should always reflect its function. Sexual dimorphism is evident, with males appearing distinctly more substantial and masculine in head and body, while females exhibit a more refined but still sturdy build.
Movement is a crucial aspect of the breed standard, with the Appenzell Mountain Dog demonstrating smooth, powerful, ground-covering gait. When trotting, the dog should show good reach in front and strong drive from the rear, maintaining a level topline. The tail remains in its characteristic curl even during movement, serving as a distinctive breed identifier. At increased speeds, the legs tend toward single-tracking, a natural and efficient pattern for sustained work. The overall impression should be one of tireless endurance combined with agility, reflecting the breed's mountain working heritage.
