How to Get Rid of Dog Dandruff: Causes & Prevention

Picture it: you’re spending time with your dog and giving them all the pets, when suddenly you notice a little white speck in their coat. Then you see another one, and another one — could it be dandruff?  

Yes, dogs can get dandruff. While finding an abundance of flakes on their skin might alarm you, mild cases of dog dandruff are often manageable. In some instances, simple lifestyle changes can help your dog get their healthy coat back. Learn what causes these pesky flakes and how to get rid of dog dandruff. 

Key Takeaways

• Dog dandruff appears as dry or oily white or yellow flakes in the coat. 
• The most common reasons for dog dandruff may include obesity, food or environmental allergies, dry air, poor grooming, lack of nutrition, and parasites. 
• Consult a veterinarian if your dog’s symptoms are accompanied by scabbing or abnormal behavior like excessive scratching. 

7 Common Causes of Dog Dandruff 

Dog dandruff looks like white or yellow flakes in dogs’ hair or fur, commonly found around their back or on the tail. 

If your dog is itching, it may be more than just an uncomfortable sensation. Persistent scratching could lead to a variety of issues, such as:  

• Hair loss 
• Scabs 
• Small bumps 
• Rashes 

Cause #1: They’re Overweight 

Being overweight may make it harder for your dog to self-groom (this could mean licking, shaking, or rolling to remove debris). Lack of ability to self-groom can contribute to flaking, skin oil imbalances, increased shedding, and potential infections in skin folds. 

To rule out this cause, keep your dog in shape, feed them a balanced diet, and maintain their grooming and bathing schedules if they need a little extra help keeping their coat clean. 

Cause #2: Improper Grooming 

Depending on their breed and coat type, some dogs need more trips to the groomer or at-home grooming sessions than others. Improper grooming or grooming mistakes like overgrooming may contribute to dandruff. For example, using the wrong shampoo or bathing your dog too often can strip the coat’s oils. 

Keep up with grooming sessions (whether at home or at the groomer’s) and use a dog shampoo best suited for your dog’s skin and coat.  Bathing frequency and grooming schedules depend on the breed and your dog’s individual needs, but many dogs benefit from baths every two to four weeks. Your vet might even prescribe medicated dog dandruff shampoo to hydrate and moisturize the skin.

Cause #3: Endocrine Disorder 

Endocrine-related conditions can produce dandruff due to oil overproduction or underproduction on your dog’s skin. When there’s an imbalance in their endocrine system, you may notice hair loss, a notable change in coat color, dryness, or even skin discoloration.  

Endocrine-related disorders such as hypothyroidism (a hormonal condition that slows metabolism) or Cushing’s disease (a hormonal condition caused by excessive cortisol production) can contribute to hair loss and often cause imbalances like dryness. Contact your veterinarian if you notice persistent skin changes or hair loss: endocrine-related conditions require a medical diagnosis and treatment from a professional. 

Cause #4: Lack of Nutrients 

Omega-3s are fatty acids that help support skin and coat health, and an absence of them can result in dry, flaky fur. Omega-3s are commonly found in fish sources but can also be found in some dog food as well. If you feel your dog could benefit from additional omega 3s, supplements are also a great way to add some of this nutrient to your dog’s daily intake. 

 A veterinarian can help determine whether your dog would benefit from a specialized prescription diet or higher-quality, over-the-counter food to meet their nutritional needs.  

Cause #5: Dry Air  

Does your skin get dry or itchy when it’s cold out? Your dog’s skin is affected in a similar way. Low humidity can sometimes lead to dryness and dandruff, so it’s important to prevent dry air in your home—especially during the winter. 

Try to keep air levels comfortable for all in your household. Using a humidifier in your home can help support your dog’s skin health in dry conditions. A bonus: humidifiers are great for people as well! They can help provide respiratory relief and help prevent irritation on your own skin. 

Cause #6: Parasites 

Fleas, ticks, mites, and lice...oh my! All these parasites can make your dog itch and potentially lead to dandruff.  Be sure to check your dog regularly to ensure their fur is clear of any visitors, especially after spending time outside. Look closely in areas where fleas and ticks like to hide, such as your dog’s head, neck, and paws. 

Vet-recommended flea and parasite prevention products can also help keep your dog’s coat free of pesky critters. For extra protection, you can apply repellents in the yard to keep away fleas, ticks, and other pests.  

Cause #7: Food Allergies 

Chicken, dairy, beef, wheat, gluten, eggs, and corn are among the most common allergies in dogs. If your dog is experiencing a reaction to an allergen, this can lead to itching and dandruff. Pay attention to your dog’s daily diet and watch for signs of reactions like scratching or rashes. 

Consult your veterinarian before switching out your dog’s food to decide if an allergy is present. Addressing your furry friend’s allergies can significantly reduce flakes and dandruff. 

“Flake” It Off 

Dandruff is common among dogs and people, but you don’t have to let it stick around! Giving your furry friend the care they need will help prevent those annoying flakes and promote their overall wellness.
