The Patterdale Terrier shares the compact, functional build of the Lakeland Terrier, a body engineered over generations for one very specific job: pursuing foxes through the narrow, rocky underground passages of the Lake District fells. Everything about this dog's physical structure serves that purpose. The breed stands approximately 14.5 inches at the shoulder, with males weighing around 17 pounds and females slightly less. The overall silhouette is square, with the length of body from point of shoulder to buttocks equal to the height at the withers. This square proportion provides agility and balance on steep, uneven terrain while keeping the dog compact enough to maneuver in confined underground spaces.
The head is well-proportioned to the body, broad and flat on top with strong, punishing jaws that are essential for a terrier expected to confront foxes underground. The muzzle is broad and strong, roughly equal in length to the skull, with a definite but not overly pronounced stop. The nose is black, though liver-colored noses are acceptable on liver-coated dogs. The eyes are moderately small, oval-shaped, and set well apart, conveying an alert, confident expression. Eye color varies with coat color but should be as dark as possible. The ears are small, V-shaped, and fold above the topline of the skull, carried alertly and dropping forward close to the head.
The neck is clean, slightly arched, and of moderate length, providing the reach necessary for underground work while maintaining a balanced appearance. The chest is one of the breed's most functionally important features. It is narrow and oval-shaped, designed to allow the dog to squeeze through tight rock crevices and narrow borrows that would stop a broader-chested terrier. The ribs are well-sprung but not barrel-shaped, creating a body that is deep enough for good lung capacity but narrow enough for passage through restricted spaces. The topline is level, the back strong and moderately short, and the loin muscular and slightly arched.
The legs are straight, well-boned for the breed's size, and set well under the body. The forequarters have well-laid shoulders that allow freedom of movement in tight quarters. The hindquarters are strong and muscular with good angulation, providing the driving power needed to scramble over rocky fell terrain and push through underground passages. The feet are round, compact, and well-padded, built for traction on wet rock and rough ground. The tail is traditionally docked to a length that provides a useful handle for pulling the dog from a borrough, though undocked tails are increasingly common where docking is prohibited. When undocked, the tail is carried high but not curled over the back.
The coat is a defining characteristic that separates the Lakeland and its Patterdale working relatives from smoother-coated terrier breeds. The double coat consists of a hard, wiry outer coat and a soft, dense undercoat that together provide excellent protection against the cold, rain, and rough underground conditions of the Lake District. The outer coat lies close to the body and should feel crisp and dense to the touch. Acceptable colors include blue, black, liver, red, and wheaten, with or without tan markings. A small white patch on the chest is permissible. The saddle marking, where the body color is darker than the head and leg color, is a characteristic pattern in the breed. This weather-resistant coat allowed fell terriers to work in some of England's most punishing conditions, where rain, cold winds, and rocky terrain are constants rather than exceptions.
Movement reflects the breed's working origins. The gait is free and ground-covering, with good reach in front and strong drive from behind. The breed moves with the effortless efficiency of a dog built for sustained activity over rough ground, the topline remaining level throughout. This sound, efficient movement was developed not for the show ring but for the practical demands of a terrier that needed to cover miles of fell country and still have the energy to work underground when quarry was found.

Shedding Level
★★☆☆☆
The wiry double coat sheds moderately, producing manageable amounts of loose hair that are easily controlled through regular brushing.
Coat Grooming Frequency
★★★☆☆
Weekly brushing maintains coat health for companion dogs, while show dogs require periodic hand-stripping to preserve the correct wiry texture and harsh outer coat.
Drooling Level
★☆☆☆☆
The breed's clean, tight lip structure produces virtually no drool, keeping the dog and its surroundings notably clean and dry.
Coat Type
