How Long Do Westies Live? Lifespan & Health

The West Highland White Terrier — the cheerful, white-coated 'Westie' — is one of Britain's best-loved small terriers. Originally bred in Scotland to hunt rats and foxes, this bold, sturdy little dog is generally robust and long-lived, but it does have a few well-known health predispositions. Here's how long Westies live, what to watch for, and how to help yours stay healthy.

How long do Westies live?

Westies typically live to around 12–16 years. As a small, hardy terrier they often enjoy a good innings, and many stay lively well into double figures. Lifespan varies from dog to dog, but sensible weight management, dental care, prompt attention to the breed's known skin issues and routine preventive vet care all influence both how long and how well your Westie lives. A healthy, well-cared-for Westie is a long-term family member.

Skin and allergies

The single most characteristic Westie health issue is atopic dermatitis — an allergic skin condition that causes chronic itching, redness, licking and recurring ear infections. It's triggered by environmental allergens such as pollen, dust mites and grass, and the breed is strongly predisposed to it. It can't usually be cured, but it's very manageable with the right vet-led plan, so any persistent scratching, paw-chewing or sore skin deserves a prompt check. Regular bathing with a vet-recommended shampoo, flea control and good grooming all help.

'Westie jaw' (CMO) in puppies

Westies are one of the breeds prone to craniomandibular osteopathy (CMO), sometimes nicknamed 'Westie jaw'. It's an abnormal bone growth affecting the jaw and skull in young, growing puppies, causing pain, swelling and difficulty eating, usually between three and eight months old. Most cases settle as the puppy matures, and your vet can help manage discomfort along the way. It's worth knowing about if you're raising a Westie pup.

Joints and 'slipping kneecaps'

Like many small breeds, Westies can develop luxating patella — a kneecap that slips out of position, causing an intermittent skip or hop in the back legs. Mild cases are managed conservatively; more severe ones may need surgery. Keeping your dog lean takes pressure off the joints and helps.

Teeth

Small breeds are prone to dental disease, and Westies are no exception. Regular tooth brushing, vet dental checks and appropriate dental care products go a long way to preventing painful gum disease and tooth loss later in life.

Lungs in older dogs

Some older Westies develop idiopathic pulmonary fibrosis, a progressive scarring of the lung tissue seen more in this breed than most. Signs include a persistent cough, reduced exercise tolerance and faster or laboured breathing. There's no cure, but a vet can help manage symptoms and quality of life — so any new breathing changes in an older Westie should always be checked.

Exercise, weight and everyday care

Despite their small size, Westies are active little terriers and need proper daily exercise — around an hour of walking and play for a healthy adult — to stay fit, lean and content. Keeping your dog at a healthy weight is one of the most powerful things you can do for its long-term health: excess weight strains the joints, worsens many conditions and shortens life. Measure meals, go easy on treats, and check your dog's body condition regularly. Good daily activity and mental stimulation also keep this clever, busy breed happy and out of mischief.

Helping your Westie live well

• Keep them lean — easier on the joints and better for overall health.
• Stay alert to itching and ear problems — given the strong allergy predisposition, early treatment really matters.
• Look after the teeth — brush regularly and keep up dental checks.
• Watch older dogs for coughing or breathlessness — and get it checked promptly.
• See your vet regularly, moving to twice-yearly checks as your dog ages.

When to see your vet

Book a check if you notice persistent scratching, licking or red skin, recurring ear infections, a skipping or hopping back leg, jaw swelling or eating difficulty in a puppy, or — especially in an older dog — a new cough or reduced stamina. Westies are cheerful and stoical, so taking subtle changes seriously is well worth it in this breed.
