West Highland White Terrier

The Westillon is a hybrid breed that results as a mix between a West Highland White Terrier and a Papillon. The result is a courageous, outgoing pup, with teddy bear looks and plenty of energy. They are intelligent and relatively easy to train, which means they excel in agility and obedience trials. Westillons love people and their playful nature makes them great companions for families with children who know to respect their boundaries. They may develop separation anxiety and become destructive when left alone for too long. Luckily, these curious, portable pups are happy to go everywhere with you!

Westillon Breed History

West Highland White Terriers originate in Scotland and are directly related to a number of other Terriers including the Scottish, Skye and Cairn. Westies were used to hunt rats and other small animals, particularly foxes. Sometimes they would even charge into underground dens to retrieve badgers or other creatures. This is why they have such strong tails – so that their owners can pull them out in the event that they become stuck. Originally these Terriers came in a variety of colors, but that was put to an end for safety reasons. One unfortunate day Colonel Malcolm of Poltalloch was hunting and accidentally mistook his prized Terrier for a fox, and shot it. After that he bred only white Westies, so there would be no mistaking their identity while on the hunt. Their intelligence and playful personalities have made these pups popular pets over the years since their induction into the American Kennel Club in 1908. Descended from Spaniels, the origins of the Papillon breed have been traced back to as early as the 1500s. Dogs resembling the Papillon were featured in paintings by notable artists such as Rembrandt and Watteau. They were given their name, which means “butterfly” in French, because of their large, pointy ears, fringed with flowing hair. Interestingly, not all pups in a litter will have these pointy ears; the pups with drop ears are called Phalenes, meaning “moth.” The Papillon was a popular fixture in the court of Louis XIV, and it is even said that Marie Antoinette carried her prized pup to the guillotine with her. Papillons are the ultimate companion dog as they have been bred as such for hundreds of years. They were first recognized by the American Kennel Club in 1915. The Westillon is a new hybrid breed, and not much is known yet about its history. Its parent breeds are both lively, affectionate, and adorable dogs and it’s no doubt that Westillons have inherited their wonderful characteristics!

Westillon Breed Appearance

The Westillon has a long coat which it inherits from both of its parent breeds. The coat may be completely white, just like a Westie’s, or it may be white with markings of any color, reminiscent of the Papillon. The coat may be soft like that of the Papillon, or rough like a traditional Terrier coat, or somewhere in the middle. Westillons have round, brown eyes and black noses. The hair around their eyes, ears, and feet is longer than the rest of their coat, giving them a teddy-bear like appearance. Their ears are large, erect, and forward pointing. They have a rectangular body, with their legs being slightly shorter than their abdomen. Their tail may be straight or curl over their back. The skin around their eyes and mouth with be black, and their teeth will meet in a scissor bite.

Westillon Breed Maintenance

The Westillon inherits a medium to long outer coat from both of its parent breeds and could inherit the Westie’s thick undercoat as well. Despite the length, their coat is easy to maintain and does not shed much. Weekly combing will eliminate tangles and prevent matting. Dirt can usually be brushed out, and the smell level for both parent breeds is low, so Westillons can be bathed on an as-needed basis. They may require trimming of the hair around the eyes, ears and paws; these are the spots most susceptible to matting. These pups are prone to ear infections because their long hair can trap dirt and moisture inside, so check weekly for signs of irritation. Daily tooth brushing is also recommended for small dogs.

Westillon Temperament

The Westillon is an outgoing, confident pup, just like its parent breeds. Their personalities are much bigger than their tiny bodies would lead you to believe. They could be described as “Type A,” as they would much rather go on an adventure than cuddle. But they don’t want to go alone! Despite being independent, these dogs love to be with their humans and may develop separation anxiety if left alone for too long. They are protective and will raise an alarm when someone comes to your door, but they will quickly make friends, thus making sub-par guard dogs. Both the West Highland White Terrier and the Papillon typically get along well with other dogs, so it’s safe to assume the Westillon is the same way. However, Westies are known to have a prey drive so Westillons may be prone to chasing cats and other small pets. Westillons are young at heart and love youthful energy, but may not be great with children because they are feisty and can become snappy when irritated. However, if they are socialized with kids who respect their boundaries they will make great companions. These intelligent pups are easy to train, but may inherit the Westie’s stubborn attitude, so reward-based training will likely work best. 

Westillon Activity Requirements

The Westillon is an energetic dog and should be walked or played with for at least 30 minutes each day. Both of their parent breeds are energetic and intelligent which means that exercise is important for both their body and their mind. Westillons enjoy the opportunity to explore and run around. They will play well with other dogs, and most likely be great fetch partners. When they have been well exercised they are happy to hang out with you at the house, but they enjoy have toys to keep them busy during downtime. Westillons will make great apartment pets as long as they receive enough exercise, otherwise they may become yappy and annoy your neighbors. They love to run around in fenced yards, or simply go for a walk with you. They will do well in most climates, but their Papillon relatives lack an undercoat and thus are very sensitive to the cold. Be sure to buy your Westillon a warm jacket if you live in a colder climate.

Westillon Owner Experiences

9 Years
3 People
Beau is a 9 year old westie x papillon. He has a brindle coat similar to that of a cairn. He has up right ears with some papillon ear hair Tufts. At the age of 5 Beau had to have major spinal surgery after he slipped a disc in his spine which was then restricting his spinal cord. He made a full recovery, but does still occasionally get mild pain in his back and neck. Our vet is treating him for arthritis now though. He's still a very happy, cheeky and friendly dog, young at heart. Westillons or westie x Papillons are wonderful family dogs.
