What your westie eats matters more than it does for most breeds, because the number one health issue in westies – skin allergies – is directly influenced by diet. The wrong food triggers inflammatory responses. The right food supports the skin barrier and reduces flare-ups. Getting this right early saves you money and saves your dog discomfort.
What to Look for in Westie Food
Novel or limited-ingredient protein sources. Duck, salmon, venison, and rabbit are all good options. Fish-based foods are particularly useful for westies because omega-3 fatty acids support skin health – and skin health is job number one with this breed.
Avoid the most common allergens. Chicken is the single most common food allergen in dogs, and westies react to it more than most breeds. Beef is the second most common. Wheat, corn, and soy are frequent inflammatory triggers. If your westie has any skin issues, start by eliminating these.
Quality over marketing. “Grain-free” isn’t automatically better – some westies do fine with rice or oats. “All-natural” doesn’t mean allergy-safe. Read the actual ingredient list, not the marketing on the front of the bag.
Feeding by Age
Westie Puppies (2-12 months)
Puppies need higher protein and calorie content for growth. Feed a puppy-specific formula 3-4 times daily until 4 months, then 3 times daily until 6 months, then twice daily from 6 months onward.
Portion sizes depend on the specific food (follow the package guidelines and adjust based on your puppy’s weight and body condition), but the general principle: puppies should be gaining weight steadily without becoming round. You should always be able to feel the ribs. See our westie weight guide for weight-by-age benchmarks.
If your puppy shows early signs of skin allergies (scratching, paw licking, ear infections around 6-12 months), consider switching to a limited-ingredient food before the allergy pattern establishes itself.
Adult Westies (1-7 years)
Twice daily feeding works for most adult westies. Measure portions rather than free-feeding – westies don’t self-regulate well, and weight management is critical for their joints and breathing.
The base food should be consistent. Constant switching causes digestive upset and worsens food pickiness (which westies are already champions at). If you want variety, keep the base food stable and rotate toppers: plain pumpkin puree, a sardine, cooked sweet potato, or vegetables.
Senior Westies (8+ years)
Activity decreases, so calorie needs decrease. But protein needs stay the same or increase to maintain muscle mass. Look for senior formulas that are lower in calories but maintain quality protein levels.
Joint support ingredients (glucosamine, chondroitin) in the food or as supplements become relevant as westies age. Omega-3 supplementation for ongoing skin support. Discuss specific needs with your vet based on your senior westie’s health status.
The Picky Eater Challenge
Westies are notorious for food boredom. Sami loves most foods in the beginning and then gets bored and refuses them after a few days. He can refuse to eat for a full day without anything being medically wrong – pure pickiness.
The rules I follow: don’t panic, don’t switch the base food, and don’t cave to the pressure. Offer food at meal times. If it’s untouched after 15 minutes, pick it up. Offer again at the next meal. A healthy westie won’t starve themselves. If food refusal goes past 3 days or comes with lethargy or vomiting, that’s a vet visit.
The location trick works for us: Sami will refuse breakfast in his usual kitchen spot, then eat the exact same food enthusiastically if I move the bowl to the yard. Change the location before changing the menu.
Diet for Skin Health
Since skin allergies affect the majority of westies, diet-as-skin-care deserves its own emphasis. The most impactful dietary strategies for westie skin health:
Eliminate known allergens (chicken, beef, wheat, corn, soy). Add omega-3 through fish-based food or supplements. Keep treats clean – check every ingredient list, because one chicken-based treat per day can maintain a food allergy. Consider home-cooked food if commercial options aren’t resolving skin issues (with vet guidance on nutritional completeness).
