Dandruff in Dogs

If you’ve observed white flakes in your dog’s coat, you might be questioning whether they have dandruff and if dogs are susceptible to it. Indeed, dogs can experience dandruff, which is also known as seborrheic dermatitis, a condition common to both humans and dogs.

Dandruff in dogs is usually not indicative of a severe issue, but it’s advisable to consult a veterinarian to determine its cause. It’s important to schedule an appointment promptly if you notice symptoms such as intense itching or noticeable changes in weight or behavior. Below, you’ll find essential information about the various types of dog dandruff, signs to watch for, potential causes, and the most effective treatment options available.

Types

Dandruff in dogs can manifest in various forms, not exclusively as white flakes. It can present as either dry or oily, or it might not even resemble typical dandruff. The affected skin may or may not exhibit redness or patches due to hair loss. Here are the most prevalent types:

  • Seborrhea sicca (dry seborrhea): This type of dandruff appears as white flakes accompanied by crusty skin.
  • Seborrhea oleosa (oily seborrhea): Dogs with this condition may have oily skin and emit an odor.
  • Walking dandruff: If the dandruff appears to be mobile, it could be Cheyletiella, a type of mite.

What Causes Dog Dandruff?

Several factors can contribute to dandruff in dogs, such as:

  • Allergies
  • Deficiency in vitamins, particularly omega fatty acids
  • Hormonal imbalances
  • Genetic predisposition, notably observed in breeds like American Cocker Spaniels, West Highland White Terriers, English Springer Spaniels, and Basset Hounds
  • Low humidity leading to skin moisture loss and dryness
  • Various health conditions including hypothyroidism, autoimmune disorders like pemphigus, and diabetes mellitus
  • Cheyletiellosis, also known as “walking dandruff,” caused by visible white mites that lay eggs in the dog’s fur, resulting in severe itching
  • Bacterial and fungal skin infections

Diagnosis

To determine the underlying cause of dandruff in dogs, a veterinarian may undertake the following diagnostic procedures:

  • Conduct a thorough physical examination
  • Inquire about the duration of dandruff occurrence, the presence of scratching or other signs of discomfort, and details regarding the dog’s diet and water consumption
  • Collect skin samples through scraping and examine material from the dog’s hair to identify mites or lice
  • Recommend allergy tests, such as a food elimination diet or intradermal skin test, if allergies are suspected
  • Examine skin cells and debris from the dog’s ears to detect yeast or bacterial infections
  • Consider a tissue biopsy to investigate the possibility of cancer
  • Perform blood tests to screen for conditions including diabetes mellitus, Cushing’s disease, and hypothyroidism characterized by low levels of thyroid hormone.

Home Remedies and Treatments for Dog Dandruff

For simple cases of dandruff prevention, maintaining good nutrition and regular grooming practices are recommended. Some veterinarians may advise incorporating omega-6 fatty acids into the dog’s diet, although it’s crucial to consult your vet before making any dietary changes.

Discuss with your veterinarian for suitable at-home remedies tailored to your dog’s needs. Avoid using human anti-dandruff products on dogs as they can be harmful.

Additional treatment options may involve:

  • Regular bathing using oatmeal-based or soothing dog shampoos like Virbac Epi-Soothe. Persistent dandruff might necessitate prescription shampoos to soothe itchy and irritated skin.
  • Frequent brushing to stimulate the skin and distribute natural oils across the body. Choose the appropriate brush based on your dog’s coat type. Options include FURminator de-shedding tools for various coat lengths, de-matting brushes, and shine/condition soft-bristle brushes.
  • Mite infestations (cheyletiellosis) require thorough treatment due to their ability to survive on surfaces for up to 10 days. Pets with mites should be bathed 6 to 8 times weekly, and vets may prescribe rinses containing insecticide and lime sulfur, alongside oral medications.
  • Clean bedding, kennels, and rugs to prevent reinfestation.
