The Appenzeller Sennenhund presents a striking picture of power, agility, and balance. This medium-sized dog exhibits a slightly rectangular body outline, being slightly longer than tall, which contributes to its efficient working gait. Males typically stand 20 to 23 inches at the shoulder and weigh between 55 and 70 pounds, while females measure 19 to 22 inches tall and weigh 48 to 65 pounds. The breed displays notable sexual dimorphism, with males appearing decidedly masculine without coarseness and females showing refinement without frailty. The overall impression is one of a robust, athletic dog built for endurance and versatility in demanding mountain terrain.
The head is proportionate to the body size and features a slightly wedge-shaped skull that is flat and broad between the ears. The stop is clearly defined but not abrupt, transitioning smoothly from skull to muzzle. The muzzle is strong and slightly shorter than the skull, tapering gradually toward a black nose. The jaws are powerful with a complete scissor bite. Eyes are small, almond-shaped, and dark brown in color, conveying an intelligent, lively expression. The breed standard considers light eyes a fault. Ears are set high and wide, triangular in shape with rounded tips, and hang flat against the cheeks when relaxed. When alert, the ears lift at the base and rotate slightly forward, a characteristic expression of attentiveness.
The neck is strong, muscular, and of medium length, flowing smoothly into well-laid-back shoulders. The topline is firm and level, showing strength without any sign of weakness. The chest is broad, deep, and reaches to the elbows, providing ample room for heart and lung capacity essential for working at high altitudes. The ribs are well-sprung, neither barrel-shaped nor flat. The loin is short, strong, and slightly arched, connecting to a gently sloping croup. The underline shows a moderate tuck-up, contributing to the athletic appearance without suggesting weakness or excessive refinement.
The forequarters feature well-angulated shoulders with the shoulder blade and upper arm of approximately equal length, meeting at an angle that allows for efficient, ground-covering movement. The legs are straight, parallel when viewed from the front, and well-boned without being coarse. Pasterns show slight angulation, providing necessary shock absorption. The hindquarters are muscular and powerful, with well-angulated stifles and hocks. The rear legs stand parallel when viewed from behind, with well-developed thighs that demonstrate the propulsion power needed for mountain work. Feet are compact, round, and tightly knit with well-arched toes and thick, black pads.
One of the breed's most distinctive features is its tail, which is set high and carried in a tight curl over the back when the dog is alert or moving. The tail forms a complete circle or "wheel" and may touch the back or fall to one side. This characteristic tail carriage immediately distinguishes the Appenzeller from its Swiss cousins. The tail is moderately thick at the base and tapers toward the tip, covered with bushy hair that enhances its visual impact.
The coat is double-layered, consisting of a close-lying, harsh outer coat and a thick undercoat in black, brown, or gray. The coat length is short to medium, lying flat against the body and showing a healthy sheen. The texture is firm and weather-resistant, providing protection from Alpine elements. Slight waviness is acceptable, but the coat should never be soft, silky, or fluffy. The hair is somewhat longer on the chest, belly, and backs of the legs, with particularly full feathering on the tail.
The breed's striking tricolor pattern is one of its most recognizable features. The base coat color is either black or brown (referred to as Havana brown), with symmetrical white markings and rich rust-red or tan points. White markings include a distinctive blaze running from the top of the head down over the muzzle, white on the chin and chest, white on all four feet, and a white tail tip. Rust markings appear above the eyes as "eyebrows," on the cheeks, on the chest as two triangles separated by white, on either side of the white chest blaze, on all four legs, and under the tail. The symmetry and clarity of these markings contribute to the breed's eye-catching appearance. Too much white or asymmetrical markings are considered faults.
Movement in the Appenzeller Sennenhund should be free, balanced, and ground-covering with good reach in front and strong drive from behind. The gait displays effortless efficiency, with the legs remaining parallel and moving in straight lines. At increased speeds, the legs angle inward toward a centerline beneath the body. The breed should move with purpose and vigor, never appearing sluggish or restricted. The topline remains level during movement, demonstrating proper structure and fitness. This efficient gait reflects the breed's heritage as a tireless working dog capable of covering rough mountain terrain throughout long workdays.
