Things to Look for in the Best Dog Foods for Westies
Start With the Skin
Most breeds get fed by size and life stage. Not Westies.
The West Highland White Terrier is one of the most allergy-prone breeds in the world. Itchy, inflamed skin, rust-colored stains on the paws from constant licking, and recurring ear infections are the reasons Westies land in veterinary offices more than almost anything else. Food will not cure environmental allergies — pollen and dust mites are usually the trigger, not the kibble — but the wrong diet makes a struggling dog worse.
Check the Protein Source First
True food allergies affect a minority of itchy Westies. When they do show up, the trigger is almost always a protein the dog has eaten for years. Beef, chicken, and dairy top the list.
If your Westie has been scratching on a chicken-based formula since puppyhood, a novel protein is worth trying before anything more involved:
– Salmon
– Duck
– Lamb
– Venison
Experiment and find out what works best for your Westie.
Look for Named Omega-3 Sources
“Supports healthy skin and coat” on the front of the bag is marketing language and doesn’t tell Westie owners what they need to know. What matters is EPA and DHA — the omega-3 fatty acids from marine sources — and whether the manufacturer discloses how much is in there. Learn how to read a dog food label.
What to look for in the best dog foods for Westies:
– Fish oil or salmon oil named in the first third of the ingredient list
– EPA and DHA listed by amount in the guaranteed analysis, not a vague “omega-3 fatty acids” percentage
– Zinc and vitamin E, both of which support skin barrier function
Flaxseed appears as a cheaper substitute on many labels. Dogs convert plant-based omega-3 into EPA poorly, so it is not an equal swap.
Match the Kibble and the Portion to the Dog
A Westie stands about 11 inches and carries 15 to 20 pounds. Small-breed formulas exist for two reasons that both apply here: the jaw cannot work a kibble sized for a Labrador, and a compact dog with a brisk metabolism burns more calories per pound than a large one.
The other side of that is weight gain. Ten extra ounces on a 20-pound frame is the equivalent of a serious problem on a bigger dog. Most adult Westies land somewhere between 400 and 550 calories a day, though activity level can influence that number considerably. Measure portions rather than eyeballing them, and count treats toward the daily total.
Keep Copper in Mind
Westies carry a documented predisposition to copper-associated liver disease. It is less common and less severe than what Bedlington Terriers face, and it is not a reason to avoid commercial food.
It is a reason to go easy on diets heavy in liver and organ meat, and to mention the breed predisposition to your veterinarian if bloodwork ever comes back unusual. This is one of the few genuinely breed-specific nutritional considerations for a Westie.
What to Leave on the Shelf
– Artificial colors. They serve no nutritional purpose and exist to appeal to the person pushing the cart.
– Unnamed fats and proteins. Generic “animal fat” or “meat by-product meal” with no species attached makes it impossible to track down a sensitivity.
– Grain-free as a default. The FDA investigation into grain-free diets and canine dilated cardiomyopathy has not produced a final answer, but there is no reason to require that a Westie be put on a grain-free food unless a veterinarian has identified a grain problem specifically.
Grain often gets blamed for itchy skin, but it is rarely the culprit. When a Westie does have a true food allergy, the trigger is almost always a protein the dog has eaten for years — beef, chicken, or dairy — not wheat or rice.
That is why a limited ingredient diet like Blue Buffalo LID is usually the better starting point. Fewer ingredients means fewer suspects, and a formula built around a single novel protein makes it possible to work out what your dog is actually reacting to. Many of these diets also lean on digestible vegetables and fruits for fiber and antioxidants, which supports steady digestion while you sort out the protein question.
If a veterinarian identifies a specific grain problem, a grain-free formula makes sense. The FDA has been looking at this issue since 2018 without a conclusion answer.
When Food Is Not the Answer
If your Westie is genuinely suffering — raw skin, chronic ear infections, hair loss — a better bag of kibble is the wrong first move. That is a veterinary dermatology conversation, and it may call for a prescription hydrolyzed diet.
An over-the-counter food with the right fats and a clean ingredient list helps a dog with mild sensitivity. It will not resolve atopic dermatitis. Talk to your veternarian.
