Idiopathic lymphoplasmacytic rhinitis in Dogs

Category: Airway & Lung
Breeds documented: 3
Published sources: 6

Overview

Long-lasting inflammation can develop in the lining of the nose even when no specific cause is found. In idiopathic lymphoplasmacytic rhinitis, immune cells called lymphocytes and plasma cells collect in this tissue. The resulting nasal discharge and noisy breathing can resemble fungal disease, infection, or a tumor, so the signs alone cannot establish the cause.

Signs to watch for

Mucus coming from one or both nostrils
Snoring or snorting sounds while breathing
Recurring sneezing
Occasional blood in nasal discharge

Usually recognized in middle-aged or older dogs.

When to get help Arrange a vet visit for persistent nasal discharge, sneezing, or noisy breathing.

Diagnosis and tests

Vets examine the mouth and nose and may use imaging and rhinoscopy, a camera examination inside the nose. Small nasal tissue samples are examined under a microscope for the characteristic immune cells. Fungal disease, tumors, foreign material, and dental problems must also be investigated before the inflammation is called idiopathic.
