Those white flakes in your dog's coat have causes you can address. Here's how to get your dog's skin healthy and flake-free.
What dandruff actually is
Dandruff is dead skin flakes shed faster than normal, often with a dull, dry-looking coat. A few flakes now and then are harmless, but widespread flaking, itching, or greasy patches signal the skin barrier is struggling. Common triggers include dry indoor air, low humidity in winter, infrequent or overly frequent bathing, poor diet, and reduced grooming in overweight or senior dogs who can't reach their whole body. Noticing when it appears helps you narrow the cause.

Bathe and brush the right way
Regular brushing distributes natural oils and lifts loose flakes, and it's the easiest daily fix. For baths, use a gentle, moisturizing dog shampoo — an oatmeal formula like [Burt's Bees Oatmeal Shampoo for Dogs](/products/burts-bees-oatmeal-shampoo-for-dogs) soothes dry skin, and you can compare options in our guide to the [best waterless dog shampoos](/guides/best-waterless-dog-shampoos) for quick touch-ups between baths. Avoid human shampoo, which disrupts a dog's skin pH, and don't over-bathe, which strips protective oils and worsens flaking.
Feed the skin from within
Healthy skin needs good nutrition, especially omega-3 fatty acids that reduce inflammation and improve coat quality. A fish-oil supplement such as [Nutramax Welactin Omega-3 for Dogs](/products/nutramax-welactin-omega-3-for-dogs) is a popular choice for flaky, dull coats. Make sure your dog eats a complete, balanced diet and drinks plenty of water, and run a humidifier in dry winter months. Diet changes take several weeks to show in the coat, so give improvements time before judging results.
When flakes mean something more
Sometimes dandruff points to an underlying issue — allergies, parasites like the aptly named 'walking dandruff' mite, hormonal conditions such as hypothyroidism, or a skin infection. Red flags include intense itching, hair loss, sores, a strong odor, or flakes that seem to move. If home care over a few weeks doesn't help, or you see these signs, book a vet visit. The right diagnosis turns stubborn dandruff into a solvable problem.

Frequently asked
- Is dog dandruff normal?
- A few flakes are normal, especially in dry weather. Widespread flaking with itching, hair loss, odor, or greasy skin is not — it often reflects dry skin, poor diet, parasites, or an underlying condition worth checking with your vet.
- What can I give my dog for dandruff?
- Regular brushing, a gentle moisturizing shampoo, and an omega-3 fish-oil supplement help most dry, flaky coats. Ensure a balanced diet and good hydration. If flaking persists or worsens, see your vet to rule out mites, allergies, or hormonal issues.
