Nasal Mites in Dogs: Pneumonyssoides Welfare

Canine nasal mites (Pneumonyssoides caninum) cause sneezing and nasal discharge. This guide covers welfare impacts and treatment.

Key Facts

Nasal mites are small mites living in the nasal passages and sinuses of dogs
Signs include chronic sneezing, reverse sneezing, nasal discharge, and head shaking
The condition is more common in Scandinavian countries but occurs worldwide
Diagnosis can be made by direct visualisation of mites in the nasal passages
Treatment with ivermectin or milbemycin is highly effective
The welfare impact is primarily chronic discomfort and irritation

Welfare Considerations and Management

Welfare-centred management of nasal mites requires confirmation of the diagnosis followed by appropriate antiparasitic treatment. Ivermectin (given orally or by injection) or milbemycin provide effective treatment. Multiple treatments may be needed to kill all life stages. Response to treatment is usually rapid. Investigation of persistent nasal signs should include consideration of nasal mites alongside other diagnoses. Definitive diagnosis by rhinoscopy provides confirmation.

What You Can Do

Seek veterinary assessment for persistent sneezing and nasal discharge in dogs
Request rhinoscopy or mite investigation if standard treatments have not resolved nasal signs
Complete the full treatment course as multiple doses are needed for mite control
Check in-contact dogs as nasal mites may spread between dogs in the same household
