Size and Build
Male Smooth Collies typically measure between 22 and 24 inches at the shoulder, weighing around 64 to 75 pounds, while females stand 20 to 22 inches tall, weighing between 55 and 64 pounds. This breed is medium to large, well-proportioned, with a body slightly longer than it is tall, muscular limbs, and an athletic, dignified appearance suitable for work and agility.
Coat and Colors
The Smooth Collie features a short, flat, and harsh outer coat with a dense undercoat for insulation. Acceptable colors include Blue Merle, Sable & White, and Tricolor. Shedding is moderate, with increased shedding during spring and fall, necessitating more frequent grooming during these periods.
Distinctive Features
The breed's head is wedge-shaped and blunt, with a flat skull tapering to a black nose. Eyes are medium-sized, almond-shaped, set obliquely, and typically dark brown, although merle coats may have one or two blue or flecked eyes. Ears are moderately large, set apart, relaxed when at rest, but semi-erect and forward when alert. The tail is long, carried low with a slight upward curve at rest, and raised when active.
Gender Differences
Males are generally more robust and larger, while females are slightly smaller and more refined. Both genders share similar temperamental traits, although males may exhibit stronger protective instincts, whereas females often display greater patience and calmness.
Movement and Gait
The Smooth Collie moves with a unique gait, where the front feet track close together and the back feet move parallel, showing strong thrust from well-developed hindquarters. Their stride is smooth, long, and effortless, highlighting the breed's agility and endurance in herding and active roles.
Show Standards and Faults
The breed standard discourages any exaggerations that compromise health, balance, or working capability. Achieving proper size, bite, and proportion is crucial for show success. Faults include undershot bite, weak jaws, and deviations from coat texture or color standards.
