The West Highland White Terrier — the Westie — is one of Britain’s most cheerfully characterful dogs. Their brilliant white coat, bright round eyes, and small but absolutely self-confident bearing make them instantly recognisable and perpetually popular. Westies bring enormous personality to a small package: they are curious, spirited, affectionate, and just stubborn enough to be interesting. They are also a breed with a distinctive and well-documented set of health conditions that require genuine awareness and preparation from prospective owners.

Health — Key Conditions
Idiopathic Pulmonary Fibrosis — “Westie Lung Disease”
IPF is a progressive, ultimately fatal respiratory disease that primarily affects middle-aged to older Westies:
- The lungs become progressively inflamed, thickened, and scarred, reducing their ability to expand and exchange oxygen
- Aetiology: unknown (“idiopathic”) — believed to involve a genetic predisposition combined with environmental triggers (cigarette smoke exposure is one documented risk factor)
- Symptoms (often initially mistaken for ageing): exercise intolerance, progressive difficulty breathing, chronic dry cough, audible crackling sounds in the chest, and in advanced cases, a bluish tinge to the gums/tongue
- Prognosis: generally poor — median survival from diagnosis approximately 18 months, though some dogs live 3–4 years with careful management
- Treatment: anti-inflammatory steroids (prednisolone) and supportive care. Research from the Royal (Dick) School of Veterinary Studies, Edinburgh (published 2023) suggests WLD may be similar to NSIP (Non-Specific Interstitial Pneumonitis) in humans, for which mycophenolate mofetil shows promise — ask your vet about emerging treatment options
- Exposure to cigarette / e-cigarette smoke should be completely avoided in all Westies
Atopic Dermatitis
Allergic skin disease affects an estimated 25% of West Highland White Terriers — one of the highest rates of any breed:
- Immune hypersensitivity to environmental allergens (dust mites, pollens, moulds); food components can also be involved
- Symptoms: intense itch (pruritus) causing scratching, chewing paws, rubbing face; ears, belly, and paws commonly affected; rust-red staining of fur from saliva; secondary bacterial and yeast infections
- Many dogs show first symptoms in their first year of life
- Management: allergen identification, trigger reduction, medicated shampoos, omega-3 supplementation, veterinary medications (oclacitinib/Apoquel, lokivetmab/Cytopoint), specific allergen immunotherapy
- Atopic dermatitis is manageable but rarely curable — it is a lifelong commitment. Comprehensive pet insurance from puppyhood is strongly advisable
Craniomandibular Osteopathy (CMO) — “Lion Jaw” / “Westie Jaw”
CMO is an inherited bone disease specific to several terrier breeds including the Westie that causes abnormal bone growth in developing puppies:
- Non-cancerous bony growths affecting the jaw bones (mandibles), temporomandibular joints, and sometimes skull bones
- Age of onset: typically 4–8 months
- Symptoms: intense jaw pain, difficulty opening the mouth, difficulty eating, drooling, intermittent fever — episodes are acutely painful
- Management: pain relief (NSAIDs) during active episodes; the condition usually self-resolves around 12–15 months when growth is complete, though some dogs retain enlarged jaws with lifelong chewing difficulty
- Inheritance: autosomal recessive — DNA test available. Ask breeders for CMO test results for both parents. Clear parents cannot produce affected offspring
FAQs
Are Westies truly hypoallergenic?
No dog breed is genuinely hypoallergenic. Westies do have a wiry double coat that sheds less than many breeds — but they produce dander and saliva proteins (the primary allergen sources for human allergy sufferers), and those allergens are present regardless of shedding level. People with dog allergies often find lower-shedding breeds more tolerable, and Westies may be among those; but no guarantees exist. If allergy is a concern, spending time with adult Westies before purchasing is advisable.
