Jack Highland Terrier

The Jack Russell Terrier is a compact, athletic working terrier that stands between 10 and 15 inches tall at the shoulder, with weight proportionate to height, typically ranging from 13 to 17 pounds. The breed standard emphasizes that the dog must be capable of going to ground, meaning it should be small and flexible enough to follow quarry into underground dens. The body is slightly longer than tall, presenting a balanced, square appearance when viewed from the side. The overall impression is one of a small but powerful dog built for endurance and agility rather than speed alone. The head of the Jack Russell Terrier is flat and moderately broad between the ears, tapering slightly toward the eyes. The muzzle is strong and powerful, slightly shorter than the length of the skull, with a well-defined stop. The nose is black, and the teeth meet in a scissors bite. The almond-shaped eyes are dark in color and express an intensity and intelligence characteristic of the breed. The ears are small, V-shaped, and carried in a button or drop position, falling forward close to the head. The neck is muscular and of good length, allowing the dog to maintain efficient movement while working. Jack Russell Terriers come in three coat types that are equally acceptable: smooth, which lies flat and close to the body; broken, which has some longer hair creating a slight roughness; and rough, which features longer wiry hair throughout. Regardless of type, the coat should be dense and weatherproof to protect the dog while working outdoors. The color must be predominantly white, comprising at least 51 percent of the coat, with markings of black, tan, or brown appearing mainly on the head and at the base of the tail. The tail is set high and traditionally was docked to approximately four inches, though docking is now optional in many countries. When alert, the tail is carried erect, signaling the terrier's characteristic confidence and readiness for action.

The West Highland White Terrier, affectionately known as the Westie, is a small but sturdy terrier that stands approximately 10 to 11 inches tall at the shoulder and typically weighs between 15 and 20 pounds. Males tend to be slightly larger than females, with adult males averaging around 10 kilograms compared to females at approximately 9 kilograms. The body is compact and well-balanced, presenting a slightly longer than tall profile with substantial bone for a small dog. The Westie's build reflects its heritage as a working earthdog capable of pursuing vermin through rocky Scottish terrain while remaining small enough to follow quarry underground. The head of the West Highland White Terrier is shaped to present a round appearance from the front, achieved through careful grooming of the facial furnishings that frame the features. The skull is broad and slightly longer than the muzzle, with a defined stop. The eyes are medium-sized, almond-shaped, and dark brown in color, set wide apart and deep under heavy eyebrows, giving the breed its characteristic piercing, inquisitive expression. The ears are small, erect, and pointed, set wide apart on the top outer edges of the skull, and are covered with smooth, short hair. The nose and eye rims are black, with black pigmentation also preferred on the paw pads and nails. The West Highland White Terrier's coat is one of its most distinctive features, consisting of a hard, straight outer coat approximately two inches long and a soft, dense undercoat. The outer coat is harsh and weather-resistant, originally developed to protect the dog while working in the rugged Scottish Highlands. The color is always pure white, as specified by the breed name, with no other colors or markings acceptable. The coat is traditionally groomed to create a rounded appearance around the head while the body is trimmed to reveal the natural outline. The tail is relatively short, thick at the base and tapering toward the tip, shaped like a carrot and carried upright without curling over the back. The front feet are larger than the rear feet and may be turned slightly outward for improved grip on rocky surfaces.
