Westillon

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

West Highland White Terrier

West Highland White Terrier

The West Highland White Terrier is a compact, sturdy small terrier with a distinctive all-white appearance that has made it one of the most recognizable breeds worldwide. Standing between ten and eleven inches at the shoulder and weighing between thirteen and twenty-two pounds, the Westie presents a well-balanced, substantial build despite its small stature. The breed exhibits slightly longer body length than height, creating a rectangular silhouette that speaks to its working heritage as a vermin hunter in the Scottish Highlands. The head is broad with a slightly domed skull, featuring a definitive stop and a blunt muzzle that gives the face its characteristic rounded appearance. The coat is perhaps the breed's most distinctive feature, consisting of a harsh, straight outer coat approximately two inches in length paired with a soft, dense undercoat that provides excellent protection against harsh weather conditions. This double coat naturally parts along the spine from head to tail, creating the breed's signature furnishings around the face and legs. The pure white coloration is a defining breed characteristic, with the hair around the head often styled to frame the face in a rounded shape. Grooming requirements are significant, with regular brushing needed to prevent matting and professional stripping recommended to maintain proper coat texture. The Westie's dark, almond-shaped eyes are set wide apart beneath a heavy brow, giving an alert and intelligent expression. The ears are small, erect, and triangular, carried firmly upright and set wide apart on the skull. The nose is distinctly black and quite large relative to the muzzle size. The tail is relatively short, typically five to six inches in length, carried high and covered with hard hair but not feathered. The legs are muscular and well-boned, with the front legs being straight and the rear legs providing strong driving power for agile movement.

Key Characteristics

Temperament
Temperament Temperament Temperament Temperament Temperament Temperament The Westie retains a strong prey drive from its hunting ancestry, making supervision necessary around small pets such as hamsters or rabbits. Their high energy level requires approximately one hour of daily exercise, though they are adaptable to various living situations including apartments when properly exercised. Training a West Highland White Terrier requires patience and creativity, as they respond poorly to repetitive drills and harsh corrections. Positive reinforcement methods work best with this intelligent breed, which learns quickly but may choose to ignore commands if not properly motivated. The breed ranks among the more social of the Scottish terrier breeds, generally getting along well with other dogs when properly introduced.
Health Considerations

Progressive retinal atrophy, cataracts, and dry eye represent potential vision concerns. The breed may also develop idiopathic pulmonary fibrosis, sometimes called Westie lung, a progressive scarring of lung tissue. Liver conditions including chronic hepatitis and copper storage disease can occur. Orthopedic concerns include hip dysplasia and luxating patella. With proper care and health screening, West Highland White Terriers typically enjoy a lifespan of twelve to sixteen years.

Papillon

Papillon

The Papillon is a small, elegant toy breed instantly recognizable by its distinctive butterfly-like ears that give the breed its French name meaning butterfly. Standing between eight and eleven inches at the shoulder and weighing between five and ten pounds, the Papillon presents a fine-boned, dainty appearance without being fragile. The breed displays a body slightly longer than tall, creating a balanced, harmonious silhouette that contributes to its graceful movement. Despite its delicate appearance, the Papillon possesses a surprisingly hardy constitution and athletic ability that defies its diminutive size. The head is small in proportion to the body, with a slightly rounded skull, a well-defined stop, and a fine, tapered muzzle approximately one-third the length of the skull. The eyes are dark, round, medium-sized, and alert in expression, with black eye rims that enhance their brightness. The most iconic feature is the ears, which come in two varieties. The erect-eared Papillon displays large, obliquely set ears with rounded tips, carried like the spread wings of a butterfly at approximately forty-five degree angles to the head. The drop-eared variety, called Phalene meaning night moth, features ears that hang down completely. Both varieties may appear in the same litter and are shown together as one breed in most countries. The coat is long, fine, silky, and abundant, lying flat on the back and sides while forming an impressive frill on the chest. The single coat lacks an undercoat, making grooming easier than many longhaired breeds and resulting in minimal doggy odor. The breed displays parti-color markings, always white with patches of any color including black, red, orange, tan, sable, or lemon. A clearly defined white blaze and noseband are preferred over a solidly marked head. An all-white dog or a dog with no white is disqualified from the show ring. The tail is set high, covered with a long, flowing plume, and carried arched over the back. The legs are fine-boned and straight, with distinctive hare feet featuring elongated center toes. The breed moves with a quick, free, graceful gait reflecting its alert, lively nature.

Key Characteristics

Temperament
Temperament Temperament Temperament Temperament Temperament Temperament Despite their friendly nature, Papillons serve as excellent watchdogs, quick to alert their families to any unusual activity or visitors. This alertness can sometimes manifest as excessive barking if not addressed through training. The breed responds beautifully to positive reinforcement training methods, though they can develop a stubborn streak if allowed to believe they rule the household. Early socialization and consistent, firm boundaries help prevent the development of small dog syndrome behaviors. Papillons require moderate daily exercise and substantial mental stimulation to prevent boredom-related behavioral issues. Their energy level ranges from moderate to intense, and they adapt well to apartment living provided their exercise needs are met. The breed maintains a youthful playfulness well into senior years, with a characteristic joy that endears them to their owners.
Health Considerations
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Open fontanelle, a condition where the soft spot in the skull fails to close completely, occurs in some Papillons as an inherited trait. While typically not problematic, it may increase susceptibility to brain injury. Von Willebrand's disease, a hereditary blood clotting disorder, has been identified in some bloodlines. Heart conditions including mitral valve disease become more common as Papillons age, with heart failure representing a leading cause of death in senior dogs of the breed. Collapsing trachea can affect the breed, causing breathing difficulties and a characteristic honking cough. Additional concerns include allergies, Cushing's disease affecting adrenal function, portosystemic shunts affecting liver blood flow, deafness in some bloodlines, and follicular dysplasia causing pattern baldness. Regular veterinary care and health screening help ensure early detection and management of potential issues.
