Did You Know?

Westies were developed in Scotland for fox, badger, and rat work, squeezing into rocky dens and burrows.

Their trademark white coat helped hunters distinguish dogs from quarry in heather and low light.

Like many terriers, they can be fearless "big dogs" in a small body, quick to investigate sounds and scents.

As Canis lupus familiaris, Westies share wolves' keen smell, but were selected for sociability and compact size.

The breed's harsh outer coat and soft undercoat shed dirt and weather, but need regular brushing and trimming.

Common breed concerns include atopic dermatitis, dental disease, patellar luxation, and "Westie lung" (idiopathic pulmonary fibrosis).

Unique Adaptations

  • Weather-ready double coat: harsh topcoat repels moisture, undercoat insulates during cold, damp Scottish conditions.
  • Compact, sturdy build and deep chest support endurance for hiking and scrambling over rough terrain.
  • Prick ears and bright eyes aid rapid orientation to sound and motion, useful for spotting small quarry.
  • Selective breeding for reduced fear around humans compared with wild Canis lupus, improving trainability and companionship.
  • Robust jaw and terrier tenacity suited to dispatching vermin, though they still need safe chew outlets.

Interesting Behaviors

  • Classic terrier "earthdog" instinct: digging, tunneling, and persistently investigating holes or scent trails.
  • Alert watchdog tendencies-quick to bark at novel noises, then eager to greet once reassured.
  • Strong prey drive; many will chase squirrels or rodents unless trained with recall and leashed walks.
  • Playful, confident problem-solvers who enjoy short training games and food puzzles, but may be stubborn.
  • Likes routine grooming handling when introduced early; otherwise may object to brushing, clipping, or nail trims.

Cultural Significance

A recognizable symbol of Scottish terrier heritage, the Westie reflects Highland working-dog roots. Once valued for vermin control on estates and farms, it later became a popular show and companion breed worldwide.

Myths & Legends

A long-told breed origin tale says Colonel Edward Donald Malcolm of Poltalloch chose only white terriers after a reddish dog was mistaken for a fox during a hunt.

Another Scottish account links Westie-type white terriers to the Duke of Argyll's Roseneath kennels, where pale dogs were prized for visibility on rugged moorland.

Early "Poltalloch" and "Roseneath" white terriers were spoken of as distinct strains in Highland sporting circles, before the modern West Highland White Terrier name was standardized.

Quick Take

The West Highland Terrier is a large dog in a small body. Flush with energy, stubborn and curious, even-tempered and friendly, the Westie is an independent thinker. The breed belongs to the terrier family, which includes the bull terrier and cairn terrier.

The Westie is an affectionate and loyal companion. He loves pampering as much as he loves being left alone. The dog can hike with you all day, with most of that time spent running ahead of you like a coyote.

3 Pros and Cons of Owning a West Highland Terrier

ProsCons
Good watchdog:
If you like the extra security, this is a good pet to have around. These dogs will let you know there’s a car passing by or if a squirrel‘s in a tree. That big bark’s appreciated by hunters. You’ll hear this dog from great distances and even underground.
Not a security guard:
The Terrier is likely to let you know someone’s out there. But if someone gets in the house, he’s more likely to lick your intruder’s hand than bite. This is where the ever-so-friendly pet backfires on you.
Not a shedder:
If there’s anyone in the home with respiratory issues or allergies, the Westie’s a good choice. It doesn’t shed. That means hairs are less likely to end up on your surfaces. However, pet dander potentially aggravates members of the household who could have a negative reaction.
Potential health problems:
As they age, your Scotland Westie can develop Addison’s disease, skin issues, degenerative brain disease, cataracts, and more. Their fair color isn’t compatible with the sun either. Lather her in sunscreen, especially behind the ears.
Friendly:
The Westie is an extremely friendly animal. He always put his best social foot forward upon encounters.
Other animal aggression:
It can be animal-friendly. But expect a Westie to have issues with animals they don’t know personally. Your Westie has a great capacity to get along with other cats and dogs, but on its terms. Keep her on a leash outdoors as the dog’s likely to bolt after another animal, especially smaller ones.

Evolution and Origins

West Highland Terrier

West Highland Terriers may have issues with animals they don’t know personally. Your Westie has a great capacity to get along with other cats and dogs, but on its terms.

West Highland Terriers were bred over 300 years ago in Scotland to tackle vermin and pests such as rats and mice, which were a key problem for both nobility and commoners alike.

The Malcolm clan is known to have made a concerted effort to breed these diminutive, yet feisty canines at Poltalloch. The breed itself is believed to share the same ancestry as Cairn, Dandie Dinmont, and Scottish, Skye Terriers.

It was officially given its name in 1907 when it took part in a London Show, a choice inspired by its region of origin in Scotland. The following year, it was recognized by the American Kennel Club.

Size and Weight

West Highland White Terriers are capable of growing to 20 lbs in weight.

The West Highland Terrier is a compact, sturdy dog. Males grow to 11 inches, females 10. Females can weigh, on average, between 13 and 16 pounds. Male weight ranges between 15 and 20 pounds.

Common Health Issues

The West Highland White Terrier is a purebred and is susceptible to a variety of health concerns. One concern is allergies. Terriers are susceptible to allergies that can give them itchy skin. Many of these animals experience some form of allergy by age three.

Another health issue that these Terriers are prone to is Westie Armadillo Syndrome. Also known as epidermal dysplasia, this problem shows up in dogs three to 12 months old. It’s a painful condition leading to whole-body hair loss and infection. Treatment for affected Terriers can include medication, medicated shampoo, and pulsed electromagnetic field (“PEMF”) therapy.

A third health condition these dogs may face is cataracts. Dogs can live with decreased vision, but cataracts make life difficult for your Westie. While the surgery is common, only dogs who are good candidates will qualify for the procedure. As of 2026, cataract surgery for dogs typically costs between $2,500 and $5,600 per eye, with some cases reaching $7,000 or more.

Westies are subject to joint issues. This includes loose knees, swollen jaw, hipbone atrophy, and hip dysplasia. PEMF alleviates several issues associated with joint problems, especially in the equine community.

Diseases associated with digestion are familiar to Westies and their owners. These include pancreatitis and inflammatory bowel disease. PEMF reduces the pain and swelling these diseases cause.

Yet another problem in Terriers is Addison’s disease. It presents as diarrhea, increased thirst, lethargy, excessive urination, and sudden weight loss. Addison’s is treatable. The vet can develop a plan for your white terrier.

White Shaker Dog Syndrome is a neuromuscular condition that causes tremors in small dogs. It can lead to debilitating physical impairment. Steroids are a common treatment.

Another disease that Terriers are prone to is Pulmonary fibrosis (PF). PF scars lung tissue, making breathing difficult. It’s believed the disease is the result of long-term exposure to pollution, allergens, and infections in Terriers. Showing up in canines around nine years old, the dog exhibits wheezing, shortness of breath, exhaustion, and low energy.

Temperament and Behavior

West Highland Terrier

Although West Highland terriers are good-natured, they never back down from a fight.

The West Highland Terrier is confident, fun-loving, intelligent, and bold. It’s a dog who’s pleased by something as simple as a belly rub, squeaky toy, or meal. This animal has a love for life that shows in her behavior.

The Westie is a house pet. He’s independent, more likely to find a spot in the action as opposed to being the center of it. While it’s capable of experiencing separation anxiety, it can also spend a day watching the house by itself.

The dog can be aggressive, but not necessarily a fighter. That doesn’t mean it will avoid one. In females, dominant or alpha behavior toward males is common. This breed is likely to be a nuisance to neighbors if not trained to stop barking.

Its personality traits include a tendency to vocalize frequently. It can chew up shoes and create other havoc around the house. Yet, it’s easily trained. Some more easily than others, but the result is the dog barking less and not digging in your garden.

How To Take Care of West Highland Terriers

A vet or breeder can be instrumental in all areas of Westie maintenance. They’re knowledgeable about dog breeds and can advise on what best suits your Westie’s care regimen.

The Best Dog Food

Whether kibble or wet food, most commercial dog foods can provide your Westie with the nutrients they need daily. If preparing homemade meals, make sure your Westie gets his daily caloric and nutrient intake. Many of these dogs have allergies, in which case, look for a limited ingredient or allergy care dog food.

Daily food must include proper amino acids to ensure your dog gets the protein needed for energy. It should also include fatty acids. This comes from animal fat, oils, and plant food. These components help cell growth, keep its coat nice and white, and promote healthy skin. The National Academy of Sciences suggests minimizing wheat products that don’t add nutrition or energy to your dog’s diet.

Maintenance and Grooming

Prepare yourself for daily grooming to keep your pet’s pure white coat free and clear of matting. As you run a brush through the hair, keep an eye out for signs of skin inflammation, irritation, or swelling.

Dermatitis is common among West Highland Terriers. Prevent or at least deter this with medicated shampoos and regular baths. This should be a regimen agreed upon by your vet. Otherwise, a healthier Westie only requires bathing on a two- to three-month schedule.

Trim hair below the eyes. Otherwise, you get matting and tear stains. Carefully clean around the eyes daily with a diluted hydrogen peroxide solution to remove reddish-brown tear stains. There are solutions for removing tear stains at pet stores. According to VeterinaryPartner, oral antibiotics help minimize tears and white fur staining.

Training

The easiest route is sending your Scottish white terrier to obedience school. Reach out to a local breeder, the West Highland White Terrier Club, or the SPCA to find an obedience class.

If choosing to teach at home, begin with brief sessions and simple commands like “sit” and “come.” Reward good behavior with food. “Come” is an important starting point for training. Get him to follow you indoors and then take it outdoors.

Get your Westie comfortable with her crate or bedding. Find a word like “sleep,” “den,” or “bed” to get them in the crate. Look at using the crate as a reward, not a punishment.

Another important goal is getting your dog to potty outdoors. Every two hours, take him out to the same spot. Puppies need frequent emptying. Between potties, crate him or keep him on a leash to prevent accidents in the house.

Indoor potty training requires the same setup, but with a litter box and potty pads.

Exercise

Allow your Westie to play and exercise every day. It’s the best way to keep muscles in peak condition. Daily walks, runs, and games meet the requirements of needed regular exercise. To minimize injury, Westies should not run without supervision.

Puppies

Westie puppies are adorable with a larger personality than their bodies should hold. It’s important to curb their enthusiasm and curiosity in the home. They’ll chew on anything and, until properly trained, will soil anywhere. Therefore, secure wires and cables that the dog may chew on. Move objects that they can bump into or break. Put away cleaning supplies and chemicals, plants, garbage, etc.

You may want to crate or kennel a puppy overnight so that you can sleep knowing it’s not getting in trouble. Buy something that won’t “shrink” as the puppy grows.

Work with your breeder or vet to see that your Westie is fed well and trained. Also, start potty-training as soon as possible. Put out newspaper or buy puppy-pads. Use non-hazardous wipes and disinfectants to clean behind the new dog.

You’ll want a chew toy, if not several. Fetching and soft toys keep puppies busy. Another idea is having a treat dispenser that rewards a Westie for completing tasks.

Children

You need to remember that the West Highland White Terrier may snap unexpectedly. Never leave a Westie alone with small children. Interactions should be properly supervised. A West Highland White Terrier is a friendly, affectionate animal and, in general, loves people.
