small breed
West Highland White Terrier
Bred out of the same western Highland stock as the Cairn and the Scottie and kept white on purpose, so nobody would mistake one for a fox in poor light. Westies are confident, busy, chatty and more openly friendly with strangers than most terriers, and still entirely terrier underneath. The defining cost is skin: atopic dermatitis is common in this breed, and a diagnosis means baths, medication and vet visits for life.
Pup Height
10-11 in
The standard asks for 11 in at the withers for males and 10 in for females, and sets no weight. White only - any other coloring is a fault. The outer coat is harsh and straight, about 2 in long, over a short soft undercoat, and the standard specifically faults a soft or curly one. Ears are small, pointed, carried erect and never cropped; the carrot-shaped tail is 5-6 in and should never be docked. Source: AKC breed standard.

What’s Life With This Pup Really Like?
High. Affectionate and happy on a lap once the day's patrolling is done, though a Westie is more independent about it than a spaniel.
Good. Playful, sturdy for the size and genuinely fun with children old enough to be gentle - less tolerant of rough handling than a bigger family dog.
Mixed. Fine with a dog raised alongside them and often sharp with strange ones, while rodents, rabbits and birds are unsafe and cats depend on early socialization.
High. Announcing everything was half the original job, and a Westie applies the same enthusiasm to the doorbell. Training reduces it; nothing removes it.
Higher than the size suggests. An hour a day covers a Westie, and the terrier stamina is there if you want to use more of it.
Low. The harsh double coat holds what it drops, which is why stripping matters more than vacuuming.
Merry, inventive and still playing like a puppy well into old age. Chase, tug and digging games are the favorites.
None to speak of. A neat, dry-mouthed little dog.
Reasonable, and better than the terrier group's reputation. Quick, greedy and willing in short sessions - the independence and the prey drive are the limits rather than any lack of brains.
Good for the size. Westies notice everything and report all of it, though at twenty pounds the noise is the whole contribution.
High and specific. Brushing two or three times a week, hand-stripping every couple of months, and a skin and ear routine that most Westies end up needing.
Good. Apartment or farm, city or country, a Westie settles in quickly - the real constraints are whether the neighbors can live with the voice and whether the yard can hold a digger.
Lifestyle fit
Could This Be Your Best Breed?
A Westie adapts to an apartment or a house, city or country, and asks about an hour a day plus a hand-strip every couple of months. What the breed really asks for is an owner who checks paws, ears and belly daily and can absorb an itchy dog's vet bills inside $1,300 to $2,400 a year. Skip this breed if thirteen years of managing a skin disease is not something you could face.
Living Space
Apartment or house, city or country - a Westie adapts to most of them, and the size is genuinely undemanding. Two things need planning for: a voice that shared walls make everyone's business, and a yard fence that goes deep enough, because a bored Westie excavates.
Pup Experience
Fine for a first-time owner who wants a terrier rather than a small dog that happens to be one. The temperament is cheerful and forgiving; the work is a self-rewarding bark, a prey drive that does not negotiate, and - in a good share of the breed - a skin condition that turns into a lifelong routine of baths, medication and vet visits.
Daily Pup Time
Around an hour of walking and play, a thorough brush two or three times a week, and a hand-strip every couple of months. Add a few minutes a day of checking ears, paws and belly once allergies are in the picture.
Allergies & Coat
The West Highland White Terrier scores 2/10 for shedding and 1/10 for drooling. No dog is truly hypoallergenic. The allergens come from dander and saliva, and a coat like this one holds on to them rather than spreading them around your home - which is what a groomer is clearing out every six to eight weeks.
Quirks & challenges
The Not-So-Easy Stuff
The Skin Is the Big One
Atopic dermatitis is the breed's defining problem: itching, chewed paws, recurring ear infections and a skin that thickens and darkens with years of scratching. Plan for management for life, not a cure.
Hand-Strip or Lose the Coat
The harsh white jacket is stripped every eight to twelve weeks. Clipping is quicker and cheaper, and it permanently softens the texture and tends to make the skin trouble worse.
A Voice That Carries
Announcing what was found in a rock pile was half the original job, and the mail carrier gets the same treatment. Training takes the edge off; nothing removes the instinct.
Rodents Are Still the Job
Hamsters, rabbits and birds are what the breed was made for, and a cat is a gamble unless a Westie grew up alongside one.
Diggers and Bolters
A dug-out fence line and a flower bed gone missing are both normal terrier behavior. A sanctioned digging patch works far better than arguing about the lawn.
Charming, Stubborn With It
Westies are quick and greedy enough to learn fast, and independent enough to weigh up whether they feel like it. Short sessions and good treats get much further than repetition.

Health Risks
Conditions this breed is prone to.
The condition that defines the breed's vet bills. Westies are one of the most atopy-prone breeds there is: environmental allergens set off intense itching, usually starting between one and three years old, with secondary yeast and bacterial infections and skin that thickens and darkens over time. Allergy testing, immunotherapy, Apoquel or Cytopoint, medicated shampoos and repeat ear treatment are the usual course, and the treatment is lifelong management rather than a cure.
Scarring of the lung tissue, reported far more in this breed than any other, which is why the plain name stuck. A dry cough, crackly breathing and tiring easily on walks usually appear from middle age onward, and the course is progressive with no cure - treatment manages symptoms and slows the decline. There is no screening test, so ask a breeder directly what older relatives died of.
Often called lion jaw. Extra bone builds up along the jaw and skull in puppies between roughly three and eight months, making eating and yawning painful, and the swelling can usually be felt. A DNA test for the SLC37A2 mutation exists and responsible breeders use it. The growth stops and usually recedes as a puppy matures, and pain relief carries them through in the meantime.
Copper accumulates in the liver instead of clearing, and damages it over years. Signs are vague - poor appetite, weight loss, vomiting, eventually jaundice - and blood work plus a liver biopsy give the diagnosis. A low-copper diet and chelation treatment manage many cases when caught early.
Also called Krabbe disease, shared with the Cairn Terrier - an inherited enzyme deficiency that strips the protective sheath off the nerves and causes progressive weakness in a young dog. There is no treatment, but there is a DNA test and simple inheritance, so a puppy from two tested parents cannot be affected.
Two small-dog leg problems that show up here. A slipping kneecap produces a skipping stride and needs surgery only in the worse cases; Legg-Calve-Perthes is the head of the femur dying back from a failed blood supply, painful, seen in the first year, and usually corrected surgically.
Insurance & Health Coverage
Arrange cover before the first birthday, and the reason is the skin. Atopic dermatitis usually declares itself between one and three years old, and once itching, an ear infection or a course of steroids is in the clinical notes, insurers write skin conditions out of the policy - permanently, and often broadly enough to catch the ears too.
It is also the claim most likely to be capped. Allergy testing runs into the hundreds, immunotherapy and modern anti-itch medication are monthly rather than one-off, and secondary ear and skin infections keep coming back, so a bad year adds a four-figure sum on top of the ordinary bills. What matters is lifetime cover of a continuing condition and a per-condition limit that refreshes each year - read those two lines rather than the premium.
The rest of the list splits in two. Westie lung disease and copper-associated hepatitis arrive in middle or later life and are exactly what insurance is for, which argues again for starting early. Craniomandibular osteopathy and Krabbe disease are congenital, so no policy pays for either - ask the breeder for the DNA results on both parents instead, and ask what the older dogs in the line died of.

Care needs
The Daily Routine
Grooming
A harsh double coat that needs a thorough brush two or three times a week with a slicker and a comb, and hand-stripping every eight to twelve weeks. Clipping is the common shortcut and a real loss: the texture softens for good, the coat picks up more dirt, and clipped Westies tend to have more skin trouble. White shows everything, so expect leg and beard washing between grooms, and keep baths to a vet-recommended shampoo once allergies are in play. Ears, teeth and nails on the usual schedule, with paws checked often - chewed feet are the first sign of an itchy dog.
Exercise
About an hour a day, split between a real walk and something with chase, hunt or dig in it. Earthdog, barn hunt, scent games and a sanctioned digging box all suit the breed, and a Westie is happy to spend part of a wet day working on a puzzle indoors instead.
Food & Weight
Measure the meals - at seventeen pounds a few extra treats a day show up fast, and weight sits badly on knees prone to slipping. Where allergies are suspected, a strict elimination diet run properly with a vet is worth more than switching bags every few weeks, and a low-copper diet is the treatment if hepatitis ever turns up.
Similar breeds
If This Isn’t Quite the One
Cairn Terrier
The closest relative there is - the Westie was made from the white puppies in Cairn lines, and the two were one rough Highland population until the early 1900s. The Cairn comes in any color but white, is a shade smaller and scruffier, and carries noticeably less of the skin trouble; the Westie is showier, chattier and warmer with strangers.
Scottish Terrier
Same Highland root stock and a similar size in a heavier, lower-slung frame. The Scottie is dour, aloof and firmly one-family, with a shorter life and a serious breed-wide cancer risk; the Westie is friendlier all around and longer-lived, and trades that for the allergies.
Sealyham Terrier
The other white working terrier, and calmer than a Westie by some distance - a low, heavy Welsh badger dog that clowns around at home and settles early. The catch is finding one, since the Sealyham is a Vulnerable Native Breed and usually means a waiting list, while Westies are everywhere.
