Canine Nasal Mites

Pneumonyssoides caninum is the scientific name of the nasal mites found in dogs all over the world. Both male and female dogs of all ages and breeds are affected by this infestation. But according to a report, larger breeds of dogs are more susceptible to nasal mites compared to smaller breeds. They are more commonly found in dogs above 3 years too. The mites may be transmitted from one dog to another either indirectly or by direct contact. There have been no reports about canine nasal mites affecting people.

When the dogs are afflicted by nasal mites, they may show typical symptoms such as sneezing, head shaking, face scratching, and rapid inhalation of air, often referred to as reverse sneezing. Breathing noisily with a high-pitched sound or difficulty in breathing h is usually observed. A discharge from the nose may be present, with occasional nose bleeding. The dog may appear restless, and may have symptoms similar to that of upper respiratory problems such as coughing and wheezing. The ability of the dog to pick up scents may be lowered by nasal mite infestation.

When the dog displays the typical symptoms of infestation, the veterinarian may do nasal flushing or use an endoscope to examine the nose. Flexibility of the scope facilitates the examination of the nasal passages directly, and the presence of mites as well as other possible causes of nasal irritation can be observed. The fluid from flushing can be tested for mites too. Several other tests such as x-rays of the nasal passages, biopsy, and blood tests may be prescribed to identify the exact cause of nasal irritation as many other upper respiratory tract diseases may display symptoms similar to nasal mite infestation.

There is no consensus on the ideal treatment for nasal mites in dogs, but many of the anti-parasitic drugs are effective in treating the condition. In some cases, even when the clinical signs point to mite infestation, the veterinarian may not find any mites in the nose during the examination. The affected dogs may not get relief from all the symptoms, especially if they were not due to nasal mites alone.
