Understanding and Treating Dog Dandruff: A Guide for Pet Owners

Understanding Dog Dandruff

As a dog owner, it is essential to understand the various health issues that can affect your canine friend, one of which is dandruff. Dandruff in dogs is a common condition that can be both unsightly and uncomfortable for your furry friend.

In this article, we’ll explore the different types of dog dandruff, its causes, symptoms, and how to treat it.

Types of Dandruff in Dogs

Just like humans, dogs can have different types of dandruff that can’t be treated the same way. Therefore, understanding the type of dandruff your dog has is crucial when looking for a treatment plan.

Seborrhea Sicca

Also known as dry seborrhea, this type of dandruff occurs when there is a buildup of flaky, dry, and scaly skin on your dog’s coat due to underproduction or overproduction of oils. It is caused by factors such as vitamin deficiency, low humidity, and allergies.

Seborrhea Oleosa

This type of dandruff is a result of excessive oil production due to an underlying condition such as hormonal imbalance, immune-mediated diseases, or genetic conditions. Overproduction of sebum causes the skin to become excessively oily and greasy, and as a result, the skin flakes off in small, oily pieces.

Walking Dandruff

This type of dandruff is caused by a specific type of mite (Cheyletiella) that lives on your dog’s skin and feeds on the skin’s keratin layer. Walking dandruff is more commonly found in dogs that aren’t well-groomed and those with weakened immune systems.

Causes of Dog Dandruff

Several factors could cause dandruff in dogs. Below are some common causes:


Just like humans, dogs can suffer from allergies that can lead to a dry, itchy, and flaky skin condition.

Vitamin Deficiency

Vitamins and minerals are essential in maintaining healthy skin and coat. When your dog lacks essential nutrients, their skin becomes dry, flaky, and prone to shedding.

Hormone Imbalance

Hormone imbalances such as hypothyroidism, Cushing’s disease, and other endocrine disorders could contribute to your dog’s dandruff.

Immune-related Issues

Autoimmune or immunodeficient diseases can cause dandruff and scaly skin.

Genetic Conditions

Some breeds are more prone to dandruff due to their genetic makeup.

Low Humidity

Low humidity during winter can cause skin dryness and dandruff.

Health Conditions

Illnesses such as cancer, kidney disease, and liver disease could cause dandruff in dogs.


As mentioned earlier, the infestation of a particular type of mite (Cheyletiella) can cause walking dandruff in dogs.

Diagnosing Dandruff in Dogs

Dandruff in dogs is diagnosed by a veterinarian by looking at the dog’s skin and coat condition. However, the type of diagnostic method used will depend on the severity of the dandruff and whether underlying conditions may cause it.

Below are some diagnostic methods that a veterinarian may use:

Physical Examination

The vet will conduct a physical exam to check for any redness, scaling, inflammation, or parasites in your dog’s skin.

Skin Samples

The vet may take skin samples to examine the skin under a microscope to check for any infections, parasites, or abnormal growths.

Allergy Tests

The vet may conduct allergy tests to determine if your dog is allergic to particular substances or food.

Tissue Biopsy

A tissue biopsy might be recommended to check for any cancerous growths.

Blood Tests

Blood tests may be carried out to check for underlying conditions such as hormonal imbalances, autoimmune, or immunodeficient diseases.

Treating Dog Dandruff

Once diagnosed, the vet will recommend the appropriate treatment plan. There are several ways to treat dog dandruff, depending on the severity and type of dandruff.

Home Remedies for Dog Dandruff

Regular grooming is crucial to your dog’s skin and coat health. Brushing your dog’s coat regularly helps to distribute oils and remove dead skin cells, preventing dandruff.

A few other home remedies that you could try include:

Good Nutrition

Feeding your dog a well-balanced diet with proper amounts of vitamins and minerals is essential in maintaining a healthy coat.

Omega-6 Fatty Acids

Including omega-6 fatty acids in your dog’s diet can help improve their skin’s health and prevent dandruff.

Oatmeal-based Dog Shampoo

Using oatmeal-based dog shampoos can help soothe and relieve itching and dandruff.

Professional Treatments for Dog Dandruff

If your dog has severe dandruff, the vet may recommend professional treatments such as:

Prescription Shampoo

Prescription shampoos containing salicylic acid, sulfur, or tar can help exfoliate the dry and flaky skin and prevent dandruff in dogs.


If walking dandruff is the cause, topical insecticides recommended by a veterinarian can treat the condition.

Lime Sulfur

Lime sulfur dips are also used to treat walking dandruff.

Oral Medication

Underlying conditions that lead to dandruff may require oral medications prescribed by a veterinarian.

Prevention and Maintenance for Dog Dandruff

Preventing dandruff in dogs involves maintaining proper skin and coat health. Below are some prevention and maintenance tips you can use:

Cleaning Bedding, Kennels, and Rugs

Regularly washing your dog’s bedding, toys, and other items they come into contact with can help reduce the buildup of allergens and parasites that cause dandruff in dogs.

In conclusion, dog dandruff is a common condition that can be prevented and treated with proper care and attention. Regular grooming, good nutrition, and veterinary care can help keep your dog’s skin and coat healthy, preventing dandruff and its associated complications.

Common Questions about Dog Dandruff

Dog dandruff is a common condition that affects dogs of all breeds and sizes. Dry, flaky skin, allergens, and mite infestations are some of the primary causes of dog dandruff, which can lead to constant scratching for the dog.

In some cases, dog dandruff could be a symptom of a more severe underlying condition such as diabetes or Cushing’s disease. Below are some answers to common questions about dog dandruff.

What are the

Causes of Dog Dandruff? Dry, flaky skin is one of the primary causes of dandruff in dogs.

This occurs due to an imbalance in the dog’s skin oils, which can result from several factors like a poor diet, nutritional deficiencies, stress, dehydration, and harsh weather conditions. Allergens such as fleas and pollen can also cause dandruff in dogs.

Dogs that are allergic to certain foods or environmental factors are more susceptible to dandruff. Furthermore, hypersensitivity reactions to shampoos, soaps, or other topical treatments can result in dandruff.

Mite infestations, like cheyletiella or demodex mites, can cause dandruff in dogs. The mites can infest the dog’s skin, causing it to itch and create flakiness.

Concerns about Dog Dandruff

Constant Scratching

One of the primary concerns of dog dandruff is constant scratching by the dog. Itching and scratching can lead to skin irritation, inflammation, and infection.

The loss of hair in the scratched areas can result in unsightly bald patches on the dog’s skin.

Serious Underlying Conditions

In some cases, dog dandruff could be a symptom of a more severe underlying condition such as diabetes or Cushing’s disease. Diabetic dogs may develop dandruff if their blood glucose levels are not adequately controlled.

Cushing’s disease, a hormonal disorder caused by an overproduction of cortisol, can cause hair loss and dry, scaly skin in dogs. When Should I See a Vet for My Dog’s Dandruff?

If your dog’s dandruff persists and home remedies like regular grooming, diet changes, and medicated shampoo do not help, you should see a vet. Your vet can conduct a comprehensive examination of the dog to determine if there is any underlying condition that may be causing the dandruff.

Diagnostic tests, such as skin scrapings or allergy tests, can also be done to identify the root cause of the dandruff. Additionally, if your dog exhibits other concerning symptoms such as excessive thirst or urination, lethargy, or weight loss, it is essential to seek veterinary care immediately.

These symptoms could indicate a more severe underlying condition that requires swift intervention. What Can I Do To Prevent Dog Dandruff?
