The Appenzell Mountain Dog presents a striking and well-balanced appearance, embodying the ideal combination of power and agility necessary for working in the challenging terrain of the Swiss Alps. Standing 18 to 23 inches at the shoulder and weighing between 48 and 70 pounds, the breed falls into the medium size category with males typically larger and more substantial than females. The overall silhouette is slightly longer than tall, creating a rectangular profile that allows for efficient movement and endurance during long working days.
The head is proportionate to the body with a flat, wedge-shaped skull that is broader between the ears and tapers moderately toward the muzzle. The stop is well-defined but not exaggerated, creating a smooth transition from skull to muzzle. The muzzle itself is strong and straight, approximately equal in length to the skull, ending in a black nose in dogs with black base coats and a brown nose in dogs with brown (called Havana) base coats. The jaw is powerful with a complete scissor bite, reflecting the breed's working heritage and need for functional dentition.
Eyes are small to medium in size, almond-shaped, and dark brown in color, conveying an alert and intelligent expression that is characteristic of the breed. The eyes should never be light-colored, round, or prominent. Ears are set high and wide, of medium size, and triangular in shape. When alert, the ears are raised at the base and the front edge folds forward, while at rest they lie flat against the head. The overall expression combines alertness with a certain liveliness that captures the breed's energetic temperament.
The neck is strong, muscular, and of medium length, flowing smoothly into well-laid-back shoulders that contribute to the breed's efficient movement. The body is compact and muscular with a level topline, deep chest reaching to the elbows, and well-sprung ribs that provide ample room for heart and lung capacity. The loin is short and strong, and the croup is broad and gently sloping. The underline shows a slight tuck-up, creating an athletic rather than heavy appearance.
The legs are straight and strong with moderate bone, neither too heavy nor too refined. Front legs are parallel when viewed from the front, with strong, flexible pasterns. Hind legs show good angulation at the stifle and hock joints, providing the power necessary for working in mountainous terrain. Feet are compact and round with well-arched toes and thick pads, designed for traversing rocky alpine paths. Dewclaws are typically removed on the hind legs.
One of the breed's most distinctive features is the tail, which is set high and carried in a tight curl over the back when the dog is moving or alert. The tail should form a complete circle or a tight spiral, lying flat against the back or to one side. This tightly curled tail is a hallmark of the breed and is considered essential to proper breed type. A tail that is too loosely curled, carried to the side incorrectly, or not sufficiently curled is considered a serious fault.
The coat is a short to medium-length double coat consisting of a thick, harsh outer coat and a dense undercoat. The coat lies close to the body, is weather-resistant, and has a natural sheen when properly maintained. The breed comes in two acceptable color combinations: black with white and rust markings, or brown (Havana) with white and rust markings. The distribution of color follows a specific pattern: the base color (black or brown) covers most of the body, with symmetrical white markings on the face (blaze), chest, feet, and tail tip. Rust markings appear above the eyes, on the cheeks, chest, legs, and under the tail. The precise and balanced distribution of these three colors creates the breed's striking tricolor appearance.
Movement is free, flowing, and ground-covering with good reach in front and strong drive from the rear. The Appenzell Mountain Dog moves with purpose and efficiency, able to work all day without tiring. The topline remains level during movement, and the tightly curled tail is carried proudly over the back. At a trot, the legs move in straight lines with a tendency toward single tracking at increased speed. Sexual dimorphism is evident, with males appearing distinctly masculine and females more refined without being weak or lacking substance.
