If your vet suspects nasal mites but can’t see them, further diagnostics will be recommended.Rhinoscopy (endoscopy of the nasal passages) and nasal flushing are often performed if nasal mites are suspected. Your vet will use a flexible scope with a camera to visualize and obtain nasal fluid and samples, which are then examined for the presence of nasal mites. This procedure must be done under general anesthesia.Nasal mites can be present on their own (primary) or as a result of a compromised respiratory tract due to a separate disease process (secondary). Because of this, other helpful diagnostics are often performed (before endoscopy) to help rule out other more common causes of respiratory disease. These include:Blood work and urinalysisTests for blood clotting factors if your dog is suffering from nose bleedsImaging: nasal and dental x-raysAdvanced imaging: CT scanHow are nasal mites treated?There are many treatment options available and prognosis is very good for resolution of infestation and clinical signsMany anti-parasitic medications seem to be effective in greater than 85% of casesAntihistamines and steroids may be prescribed by your vet to decrease itching and swellingMay include treating other causes of respiratory infection alongside the mitesNo real prevention other than keeping dogs away from a dog that has a current nasal mite infestation and/or concurrent respiratory diseaseRead more:Canine Nasal MitesHave more questions about nasal mites in dogs?Schedule a video consult to speak to one of our vets.
