Key Health Conditions That Affect Diet
Skin Allergies (Very Common)
The majority of Westies develop allergic skin disease. Food allergies (beef, wheat, corn, dairy) and environmental allergens both contribute. A hypoallergenic diet is often life-changing.
Copper Toxicosis
Some Westies carry genes for copper toxicosis — a condition where copper accumulates in the liver. Avoid liver, shellfish and high-copper supplements for at-risk dogs.
Luxating Patella
Common in the breed. Lean body weight reduces joint stress. Glucosamine support helps from middle age.
Pulmonary Fibrosis
Westie Lung Disease (idiopathic pulmonary fibrosis) is unique to the breed. Anti-inflammatory diet rich in omega-3s may help slow progression. Consult your vet.
Foods to Feed Your West Highland White Terrier (Westie)
✅ Best Foods for West Highland White Terrier (Westie)s
- Duck — excellent novel protein, anti-inflammatory, great for allergic Westies
- Lamb — good hypoallergenic option if not previously exposed
- White fish (cod, tilapia) — very clean, low-allergen protein
- Sweet potato — low-allergen carbohydrate, anti-inflammatory
- Salmon (omega-3s help skin significantly — if not allergic)
- Blueberries, cranberries — antioxidants that help skin and urinary health
- Coconut oil (tiny amount) — anti-fungal, skin-soothing topically and internally
❌ Never Feed Your West Highland White Terrier (Westie)
- Beef — one of the most common allergens in Westies
- Wheat and corn — common food allergens causing skin flares
- Dairy products — frequent skin and digestive allergen in this breed
- Liver and shellfish — copper toxicosis risk for genetically predisposed dogs
- Artificial additives, colours and preservatives — trigger allergic responses
- Chicken (if already sensitised — try duck or fish as alternative)

Nutrition Tips for West Highland White Terrier (Westie)s
- If your Westie has skin problems, try a strict 8-week novel protein elimination diet — it can be transformative
- Duck and white fish are the safest novel proteins for most Westies
- Omega-3 fish oil is one of the most evidence-based interventions for allergic skin disease — don't skip it

Frequently Asked Questions
Why do Westies scratch so much?
Most Westies scratch due to a combination of genetic skin sensitivity, environmental allergens (grass, dust mites, pollen) and food allergens. The most common food triggers are beef, wheat, corn and dairy. Switching to a duck or white fish-based diet for 8–12 weeks often dramatically reduces scratching in food-allergic Westies.
What should Westies not eat?
Westies should avoid beef, wheat, corn, dairy and artificial additives — these are the most common food allergy triggers. Some Westies also need to avoid liver and shellfish due to copper toxicosis risk. Introduce new foods one at a time so you can identify any triggers.
Is salmon good for Westies?
Salmon can be excellent for Westies — the omega-3 fatty acids are powerfully anti-inflammatory and help manage allergic skin disease. However, if your Westie has a fish allergy (less common but possible), it can worsen symptoms. Start with a small amount and monitor. If no reaction after 2 weeks, continue as a regular part of the diet.
