What you put in the bowl shows up in a Westie's skin, weight and energy. Here's how to feed a Westie well â including the allergy angle that matters so much for this breed.
The short answer
- Feed a complete, good-quality diet suited to your Westie's age and weight.
- Watch portions â Westies gain weight easily, and excess weight loads the joints.
- For the breed's itchy skin, omega-3s and sometimes a limited-ingredient diet help.
- Always transition foods gradually and keep fresh water available.
How much to feed a Westie
Most adult Westies eat around Â―â1 cup of quality dry food a day, split into two meals â but always follow the food's guide for your dog's weight and adjust to keep them lean. Puppies eat more often (3â4 small meals); seniors usually need a little less.

Food and the Westie's skin
Because the breed is so prone to allergic skin disease, diet matters more than for most dogs. A diet rich in omega-3 fatty acids supports the skin barrier, and if a true food allergy is suspected, a vet-guided limited-ingredient or elimination diet can help. Most Westie itch is environmental, though â don't assume it's the food without checking.
ðū From one Westie owner to another âdon't free-feed a Westie. Leave food down all day and you'll have a chunky terrier in months. Measure meals, count treats, and the skin and joints both thank you.
Treats & what to avoid
- Keep treats under ~10% of daily calories.
- Avoid known toxic foods: chocolate, grapes/raisins, onion, xylitol.
- Go easy on table scraps â they unbalance the diet and pile on weight.
- Transition any new food over 7â10 days to avoid tummy upset.
Diet helps â but skin allergies still cost
Even the best diet won't fully prevent the breed's allergic skin disease. Insuring early covers the vet care when flares happen.

It can support skin health, and a vet-guided elimination diet helps if food allergy is involved â but most Westie itch is environmental.
