You believe that you have one beautiful pooch. In your eyes, his perfection is unmarred and parallel to none. Until that is, you give him a good rub down, and you notice unsightly white flakes appearing everywhere.

You do some more scratching, and you notice your beautiful canine seems to have spots of very dry skin and even a few bumps and sores here and there. You decide you’d better keep an eye on it and decide to observe your pet for the day. In short order, you notice that your dog is itching more than usual.

Well, you’re not crazy, and the condition is not uncommon. It’s actually a case of dog dandruff. Dog dandruff is also sometimes called seborrhea (although seborrhea is actually a cause of dandruff, not the condition of dandruff itself).

Regardless of semantics, your dog can suffer from primary or secondary seborrhea. Secondary seborrhea is the most common affliction. Primary seborrhea is rare and usually genetic, so it gets passed down the family tree.

Secondary seborrhea often results from an underlying cause such as allergies or other skin issues in dogs. Despite the cause, you don’t want your dog to be itchy and uncomfortable, nor is it ideal to have him flaking all over your home. This means treatment measures are in order.

Dog Dandruff – What Causes It?

There are several different causes of dandruff in dogs. They can run the gamut of allergen-related triggers. These allergens can be both food related and environmental. Irritants like pollen and dust, household cleaners, and even the saliva of fleas can be the culprits.

Endocrine disorders like Cushing’s disease and hypothyroidism in dogs can also cause dandruff. Bacterial or fungal skin infections can cause dandruff too, although this will manifest as flakes all over the body, instead of in just one localized area.

  • Infections
  • Yeast
  • Parasites that are both internal and external
  • Abnormalities in your dog’s diet (such as not drinking enough water or not getting the proper ratio of fat, minerals, and vitamins that your dog needs)
  • Obesity
  • Even things such as temperature and humidity levels

These can all be underlying causes of dandruff on dogs. Weather conditions are especially true in the wintertime due to the low humidity levels. These low levels of moisture in the air can leech the moisture from your dog’s skin too, making him itch and scratch and flake.

This can also be said of spring and summer, especially if your dog suffers from seasonal allergies.

Occasionally dogs can suffer from dandruff due to Cheyletiella mites. This is also sometimes called “walking dandruff.” These mites like to burrow into your dog’s skin and coat and lay their eggs. Their goal is to proliferate and generally make your dog as miserable as possible.

Finally, improper grooming can also be a culprit for dandruff, so it’s important to keep your dog clean and well-groomed at all times, to prevent possible infections and infestations. Regular brushing helps to keep your dog’s coat lubricated with oil and prevent dryness and itchy flaking.

Signs and Symptoms of Dandruff in Dogs

A dog with dandruff will present with either dry, flaky skin, or oily, flaky skin, depending on the breed. Those ugly little flakes are actually dead skin cells all stuck together and flaking off.

Other signs of dandruff are itching and scratching, and you may even notice hair loss and baldness in certain areas, as well as areas where the skin appears “thick”. Scabs, bumps, and pimples can also be a sign that your dog is suffering.

If your dog does suffer from hair loss in addition to the flakiness, you should see your vet. Hair loss in dogs could be a sign of Canine Cushing’s Disease.
