Dandruff is a condition that occurs when dead skin cells are allowed to build up. Dog dandruff can be particularly troublesome for owners, as it can represent a variety of issues that may have any simple solutions; rather than being one specific health issue. Dog owners who notice a change in the amount of dandruff present on their dog should seek veterinary care, as it may be a sign of a more serious disease.

Causes
-
Some causes of canine dandruff include parasites such as cheyletiella mites, who tunnel under the dog's skin and cause severe itching and dandruff. Yeast and bacterial infections can cause changes in the skin and lead to itching and greasy scales. Some dog dandruff may be the result of other diseases such as Cushing's disease or hypothyroidism. However, dandruff may also occur because of something simple such as a sunburn.
Symptoms
-
Depending on the specific cause of the dandruff, there are several potential symptoms that may be associated with the issue. For example, cheyletiella mites can cause itching and hair loss. Sunburns can produce redness, hair loss and crusty skin. Meanwhile, diseases like hypothyroidism may be accompanied by dandruff, weight gain, lethargy and changes in the skin's pigmentation.
Diagnosis
-
When a dog is brought in for a dandruff issue, the veterinarian will likely inquire about what other symptoms the owner may have noticed. This will help him determine where to start in the diagnostic process. Diagnostic tools will vary based on the type of health issue suspected; for example―dogs with cheyletiella mites will require a skin scraping, which will be examined beneath a microscope for mite verification. Additional diagnostic tools that may be used on a dog with dandruff may include a physical examination, blood tests, a urinalysis, chemistry panel and organ function tests.
Treatment
-
Treatment for the dandruff will vary based on the underlying cause. Dogs with hypothyroidism or Cushing's disease will require treatment for those diseases; which should also clear up any skin-related issues such as dandruff. Parasites, such as cheyletiella mites, will require medicated shampoos and dips to kill off the mites. Meanwhile, bacterial or fungal infections may require anti-fungal creams, ointments or antibiotics.
Prognosis
-
Most cases of dog dandruff will clear up once the underlying cause has been identified and properly treated. These dogs can continue to live a long and healthy life and dandruff should in no way affect their lifespan. However, some diseases, such as hypothyroidism, may require life-long treatment to prevent skin issues from reoccurring.
