What are dog nasal mites? How to treat a dog with Nasal Mites.
Paws for the News!
Nasal mites are a common but rarely diagnosed mite that infects the nasal passages of dogs and wild canines.
The scientific name for nasal mites is Pneumonyssoides caninum.
What are the symptoms of a nasal mite infestation?
Infestation with the nasal mite usually does not cause any serious symptoms, however, some dogs may develop a heavy infection and will suffer from bouts of sneezing or nose bleeds. Other dogs may develop a chronic nasal discharge from the infection.
How is a nasal mite infestation diagnosed?
The mite lives inside the nasal passages, but some mites will travel to the outer edges of the nostril. A healthy dog becomes infected when it has nose-to-nose contact with an infected dog. If the infection causes symptoms, the mite can be identified by taking a swab of the nasal passage and applying it to a microscope slide. There are usually a large number of mites visible on the slide if an active infection is present.
How is a nasal mite infestation treated and prevented?
Treatment is very straightforward and consists of administering oral ivermectin. This is an off-label use of ivermectin in dogs, and the drug must be administered by or under the direct recommendation of a veterinarian. Prevention includes keeping your dog out of contact with infected or stray dogs.
Can I get nasal mites from my dog?
No. Pneumonyssoides caninum only infests dogs.
Summary
Infestation with the nasal mite is not frequently diagnosed, but should be considered as a cause of chronic sneezing, nosebleeds, or nasal discharge in dogs. Fortunately, if it is suspected, it is easily diagnosed and treated.
Etiology
Pneumononyssoides caninum a somewhat larger mite than Sarcoptes scabiei. Details of its life cycle, which is completed in the nasal passages, is lacking.
Occurrence
Probably worldwide with greater prevalence in some regions. As many as 25 % of dogs necropsied in Sweden were found to be infected. Infections are infrequent in the US.
Clinical Features
Transmission is by direct contact. Sites of infection are the nasal passages and sinuses. Infections are mainly subclinical. Heavy infestations may be accompanied by erythema of the nasal mucosa, sneezing, head-shaking, rubbing the nose and occasionally epistaxis.
Diagnosis
The mites can be seen on the nasal mucosa with a rhinoscope. They can sometimes be seen moving around the external nasal nares.
