Cheyletiellosis on Dogs Definition, Causes, Diagnosis, and Treatments | by AADG, DVM

In this client-commissioned article for Honest Paws, Dr. Gaffud explains cheyletiellosis (commonly called “walking dandruff”) in dogs: what it is, how mites cause it, how veterinarians diagnose it, and how to treat and prevent it.

Key Takeaways:

• Definition & cause: Cheyletiellosis is a parasitic skin condition caused by Cheyletiella mites that live on the superficial skin layers of dogs.

  • It is sometimes called “walking dandruff” because the mites cause large, white flakes or scales to move on the skin surface.

  • The mites are contagious, transmitted via direct contact with infected animals or via contaminated bedding/environments (fomites).

    
    

• Clinical signs: • Excessive scaling or dandruff (especially along the back, neck) • Variable pruritus (itchiness) — some dogs scratch a lot, others less so • Skin irritation, redness, possible secondary bacterial infections from scratching or broken skin

  
  

• Diagnosis: • Skin scrapings, tape-impression tests (e.g. acetate tape) to capture mites or eggs under the microscope • Because mite detection can be tricky in mild infestations, diagnosis may rely also on response to therapy.

  
  

• Treatment & management: • Topical treatments: medicated shampoos, dips, spot-on products with appropriate acaricides (e.g. fipronil, selamectin) • Oral or systemic treatments may be used in heavier infestations or when topical alone is insufficient • Environmental decontamination is critical: wash bedding in hot water, vacuum thoroughly, treat surroundings to kill mites off the host • Treat all animals in contact (dogs, cats, rabbits) to prevent re-infestation.

  
  

• Prognosis & prevention: When treated thoroughly and with environmental control, many dogs recover well. However, if re-exposed or if environmental eradication fails, reinfestation is possible.

  
  

• The article emphasizes careful diagnosis, complete treatment, and hygiene measures to reduce recurrence.
