Bostie

The Bostie is a cross between the Boston Terrier and the West Highland White Terrier. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a Bostie. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.

Boston Terrier

Boston Terrier

The Boston Terrier is a small, compact, and well-muscled dog that presents a distinctively square appearance combined with a striking tuxedo-like coat pattern that has earned it the nickname American Gentleman. Standing between 10 to 12 inches tall at the shoulder, this breed is divided into three weight classes by the American Kennel Club: under 15 pounds, 15 to 20 pounds, and 20 to 25 pounds, with the maximum weight never exceeding 25 pounds. The body is short and well-knit, with a level back and deep chest that contributes to the breed's sturdy yet refined silhouette. The length of leg balances proportionally with body length, creating the striking square profile that defines the breed standard and distinguishes this American original. The head is square and flat on top with a short, wide muzzle that is free of wrinkles and proportionate to the skull. The eyes are large, round, dark, and set wide apart, giving the breed its characteristic alert and intelligent expression that conveys both curiosity and kindness. The ears are small and erect, either natural or cropped to conform with the shape of the head, positioned at the corners of the skull. The coat is smooth, short, and fine-textured, lying flat against the body with a brilliant sheen when properly cared for. Acceptable colors include brindle, seal, or black, all with distinctive white markings that create the formal tuxedo appearance. Required markings include a white muzzle band, white blaze between the eyes, and white forechest, while desired markings extend to a white collar, white on the forelegs, and white on the hind legs to the hocks. The tail is short and fine, set low and carried below the level of the back. It may be straight or screw-shaped but should never be carried above the horizontal or docked. The breed moves with a sure-footed, straight-gaited stride that displays grace and power in equal measure, with the forelegs and hind legs moving straight ahead in line with perfect rhythm. The overall impression is of a well-balanced, determined dog that combines strength with elegance, earning the Boston Terrier its enduring reputation as the American Gentleman of the canine world.

Their sensitivity to their owners' moods makes them excellent emotional companions, responding to feelings with intuitive understanding and affection.
Health Considerations
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations The breed may also experience hemivertebrae, a spinal condition where vertebrae are malformed, potentially causing pain or paralysis in severe cases. Deafness, both hereditary and acquired, occurs in the breed, particularly in dogs with excessive white markings. Boston Terriers are prone to allergies and skin sensitivities that may require dietary management or medication. Additionally, the breed has a high rate of cesarean sections during whelping due to the puppies' large heads relative to the mother's narrow pelvis. The typical lifespan ranges from 11 to 13 years with proper care and regular veterinary attention.

West Highland White Terrier

West Highland White Terrier

The West Highland White Terrier, affectionately known as the Westie, is a small but remarkably sturdy terrier that combines compact power with an appealing, confident appearance. Standing 10 to 11 inches tall at the shoulder and weighing between 15 to 21 pounds, with males typically slightly heavier than females, this breed presents a square, muscular build that belies its diminutive size. The body is compact and well-balanced, with a deep chest that reaches at least to the elbows, a level back, and powerful hindquarters that reflect the breed's working terrier heritage. The overall impression is of a hardy, active little dog built for going to ground after small game in the rocky Scottish Highlands where the breed originated. The Westie's most distinctive feature is its brilliant white double coat, which consists of a hard, straight outer coat approximately two inches long and a soft, dense undercoat that provides excellent insulation against harsh weather. The coat covers the entire body and requires regular grooming to maintain its characteristic appearance and texture. The head is broad and slightly domed, appearing round when viewed from the front, with a defined stop and a moderately short, blunt muzzle that is slightly shorter than the skull. Dark, almond-shaped eyes are set wide apart and carry an alert, piercing expression that conveys the breed's sharp intelligence and determination. The small, erect ears are pointed and set wide apart on the outer edge of the skull, covered with velvety, smooth hair and never cropped, enhancing the breed's keen, inquisitive expression. The nose is large, black, and slightly projected over the mouth. The jaw is strong with a scissors bite and large teeth relative to the dog's size. The tail is relatively short, measuring five to six inches in length, and is shaped like an inverted carrot with a thick base tapering to a point. It is carried jauntily upright but never curled over the back, serving as a handle that was historically useful for pulling the dog from burrows. The breed moves with a free, easy gait that covers ground efficiently, displaying the characteristic terrier combination of purpose, determination, and energy that defines this spirited Scottish breed.

Key Characteristics

Temperament
Temperament Temperament Temperament Temperament Temperament Temperament Westies generally do well with older children who understand how to interact respectfully with dogs, but their terrier nature means they may not tolerate rough handling or teasing. They have a strong prey drive and will chase small animals, so careful supervision is needed around cats, rabbits, or other small pets. While they can be bossy with other dogs, proper socialization helps them get along in multi-pet households. Westies make excellent watchdogs, readily alerting their families to any perceived intrusion, though they may need training to prevent excessive barking. They are energetic dogs that enjoy daily exercise and outdoor adventures but are adaptable enough to live happily in apartments with sufficient activity.
Health Considerations
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Legg-Calve-Perthes syndrome, a condition where the blood supply to the femoral head is interrupted causing bone deterioration, occurs frequently in the breed and may require surgical treatment. Eye conditions including cataracts and keratoconjunctivitis sicca, or dry eye, affect many Westies. Copper storage disease, where copper accumulates in the liver causing damage, has been identified in the breed. White dog shaker syndrome, causing tremors in young white dogs, may also occur. Dental disease is common due to crowded teeth in their small mouths. With proper care and regular veterinary attention, Westies typically live 12 to 16 years, with the median lifespan around 13 years.
