The West Highland White Terrier is a small dog (6 to 10 kg) with a white coat and moderate energy. The breed has two known predispositions: copper accumulation in the liver and atopic dermatitis, which affects up to half of puppies by three years of age. The ideal food controls dietary copper and provides omega-3 and omega-6 for the skin.
In the current My Pet Magazine analysis, the best food for the West Highland White Terrier is Purina Pro Plan Complete Essentials (Purina Pro Plan), with a technical score of 91.3/100 (🌟 Superior Quality), calculated with the My Pet Magazine IDNM/IPFI methodology across 49 dog foods reviewed in July 2026.

What to weigh in food for the West Highland White Terrier
Two distinct concerns guide the choice of a Westie's food — one in the liver, the other in the skin.
Copper in the liver. Families of the breed carry a genetic tendency to accumulate copper in liver tissue, which in some dogs progresses to chronic hepatopathy over the years. Food helps by controlling dietary copper, one of the management measures available to slow progression in predisposed dogs.
Skin and atopic dermatitis. The Westie is among the breeds with the highest prevalence of atopic dermatitis, usually with signs already in the first year of life. Balanced omega-3 and omega-6 fatty acids in the food support the skin barrier, helping hold back inflammation and discomfort — without replacing the treatment prescribed by the veterinarian in active cases.

Breed profile and predispositions
The West Highland White Terrier's first predisposition is copper-associated chronic hepatopathy. According to UFAW (Universities Federation for Animal Welfare), the breed's predisposition suggests a significant genetic component: in certain Westie families, copper accumulates in the liver, and that accumulation is additional evidence of a genetic basis — even though the exact genes involved are not yet identified. The associated nutritional recommendation is to reduce dietary copper as part of management in affected dogs or those with a family history.
The second predisposition is atopic dermatitis. The study by Favrot and colleagues (2020), published in Veterinary Dermatology, followed a cohort of Westie puppies over the first three years of life and found a 52% prevalence of canine atopic dermatitis, with about 60% of cases beginning in the first year. The nutritional implication is omega-3 and omega-6 fatty acid support for the skin barrier, as part of management alongside veterinary follow-up.

Frequently asked questions about West Highland White Terrier food
- Does the West Highland White Terrier need a special food?
- He needs attention on two fronts: the liver and the skin. The breed has a genetic tendency to accumulate copper in the liver, which can progress to chronic hepatopathy, and it also has one of the highest rates of atopic dermatitis among dogs. A good food for a Westie controls dietary copper and provides omega-3 and omega-6 support for the skin barrier.
- Why does copper in the food matter so much for the Westie?
- Because whole families of the breed have a genetic tendency to accumulate copper in the liver — a trait documented by UFAW (Universities Federation for Animal Welfare). In some affected dogs, that accumulation progresses to chronic hepatopathy over the years. Reducing dietary copper is one of the few management measures available.
- Does the Westie frequently have skin allergies?
- Yes, it is one of the breeds most associated with atopic dermatitis. A study published in Veterinary Dermatology followed Westie puppies for three years and found atopic dermatitis in 52% of them, most with signs already in the first year of life. Omega-3 and omega-6 fatty acids in the food help support the skin barrier.
- Is hypoallergenic food indicated for every Westie?
- Not necessarily — it depends on the diagnosis. The Westie's atopic dermatitis has environmental and genetic causes; it is not always a food allergy. The nutritional point that helps every dog of the breed is omega-3 and omega-6 support for the skin; a specific elimination diet only comes into play if the veterinarian suspects an adverse reaction to some ingredient.
- How can I tell whether my Westie is at risk of a liver problem?
- You cannot predict it from behavior — copper accumulation is usually silent until advanced stages. The way forward is periodic veterinary follow-up, with liver function tests when indicated, and a food with controlled dietary copper as part of preventive management.
