Bully Jack Terrier

The Bull Terrier is a strongly built, muscular, and well-balanced dog that presents an appearance of maximum substance for its size while maintaining quality and athletic capability. Unlike many breeds, there are no specific height or weight limits in the standard, though dogs typically stand around twenty-one to twenty-two inches at the shoulder and weigh between fifty and seventy pounds, with females being slightly smaller. The body is well-rounded with a short, strong back, broad shoulders, and a deep chest. The overall impression should be of a determined, intelligent, and active dog with a keen expression. The head is the Bull Terrier's most distinctive and recognizable feature, described as egg-shaped when viewed from the front. The skull is flat across from ear to ear and curves gently downward from the top of the skull to the tip of the nose without any stop or indentation. This unique profile, sometimes called a Roman nose, creates an oval outline that is filled completely up, giving an impression of fullness without hollows or indentations. The eyes are a unique triangular shape, small, deep-set, and dark, placed close together near the top of the head, giving the breed its mischievous and intelligent expression. The ears are small, thin, and close together, standing erect. The neck is long, muscular, and clean, leading to robust, well-developed shoulders. The tail is short and set low, carried horizontally. The coat is short, flat, close, and harsh to the touch with a glossy appearance. The breed comes in two color varieties recognized by kennel clubs: white, which may have colored markings on the head only, and colored, which may be black, brindle, red, fawn, or tricolor with white markings. Brindle is considered the preferred color in colored varieties. The gait is free, smooth, and powerful, covering ground with effortless strides.

The Jack Russell Terrier is a small, sturdy, and athletic working terrier built for the demanding task of pursuing foxes underground. Standing between ten and fifteen inches at the withers and weighing thirteen to seventeen pounds, these compact dogs present a balanced, lively appearance with keen expression and alert demeanor. The body length is slightly greater than the height, creating a rectangular rather than square profile that allows for flexible movement underground. The chest must be small enough to be easily spanned by average-sized hands behind the shoulders, a practical requirement ensuring the dog can follow quarry into underground dens and bolt foxes from their burrows. Despite their small size, they possess remarkable strength, agility, and stamina. The head is proportionate to the body, appearing triangular when viewed from the front. The skull is flat and moderately broad at the ears, narrowing toward the eyes with a defined but not overpronounced stop. The muzzle is strong with powerful, well-boned jaws and muscular cheeks, reflecting the breed's working heritage and enabling a firm grip when necessary. The nose is black and fully pigmented. The eyes are almond-shaped, deep-set, and dark with a mischievous, intelligent expression that reflects their clever nature. The ears are small, V-shaped, and highly mobile, carried in button or drop position with soft, fine leather. The neck is clean, muscular, and of good length, allowing for flexible movement in tight underground passages. The coat comes in three types: smooth, broken, and rough, all of which are dense, hard, and weather-resistant, providing excellent protection from harsh conditions and thick undergrowth. Regardless of coat type, the breed is predominantly white with black, tan, or brown markings. The white coloring was specifically developed to distinguish the dog from the fox during hunts. The tail is set high and traditionally docked to provide a handhold for pulling the dog from burrows, though docking is now optional or prohibited in many regions. The gait is free, lively, and well-coordinated, demonstrating the agility and stamina required for their original work.
