Why is my dog’s skin flaky or covered in dandruff?

Read time: 3 minutes

Overview

Flaky skin or dandruff in dogs is often linked to dry skin, grooming changes, or irritation from things like shampoo, allergens or the environment. It can also happen alongside itching, so it’s worth checking for other signs as well. Most of the time, there are a few possible causes rather than one clear reason.

Things To Check

1. Check where the flakes are most noticeable, such as the back, shoulders, tail base, ears or belly.

2. Look for redness, scabs, broken skin, hair loss, swelling or a stronger smell.

3. Think about whether anything changed recently, such as shampoo, grooming, bedding, washing frequency or diet.

4. Notice whether your dog is scratching, rubbing, licking or chewing more than usual.

5. Check if the skin seems greasy as well as flaky, or if the coat looks dull and dry.

6. Consider whether the problem is worse after walks, grass contact, outdoor time or seasonal changes.

7. Look for signs of fleas or other parasites, especially around the tail base and back.

Common Causes

Dry skin is a common reason, especially in colder weather, after over-washing, or if the air indoors is dry. Mild grooming irritation can also leave the skin looking flaky.

Allergies or sensitivities are another frequent cause. These may be linked to food, pollen, dust, cleaning products or shampoos, and often come with itching.

Parasites such as fleas can cause skin irritation and dandruff-like flakes, even if you don’t spot obvious signs straight away.

Some dogs develop skin issues linked to yeast, bacteria or underlying health problems, which can make the skin greasy, sore or flaky at the same time.

What To Do

Start by keeping a simple note of when the flaking appears, how itchy your dog seems and whether anything makes it better or worse. This can help you spot a pattern.

Use a gentle grooming routine and avoid harsh washing or very frequent bathing, which can sometimes dry the skin further. If you do bathe your dog, choose a mild, dog-friendly shampoo and rinse it out thoroughly.

Check bedding, grooming tools and your home environment for anything that could be irritating the skin. Regular cleaning of beds and shared surfaces can help support good skin hygiene.

If your dog’s coat is dry, dull or prone to tangles, regular brushing can help remove loose flakes and keep the coat comfortable. Make changes one at a time so it’s easier to see what helps.
