Pink Growths in the Nose in Dogs

Nasal Polyps in Dogs

Nasal polyps refer to protruding pink polypoid growths that are benign (not cancerous), and that are found to arise from the mucous membranes – the moist tissues lining the nose. The symptoms caused by nasal polyps can mimic illness, but do not respond to antibiotic therapy.

Symptoms and Types

  • Nasal congestion
  • Nasal discharge that is unresponsive to antibiotics
  • Sneezing
  • Decreased nasal airflow
  • Noisy breathing, especially when inhaling


The causes of nasal polyps are unknown. It is suspected that congenital processes may be to blame (in which the tendency to develop this type of condition is passed on to offspring while in utero), or alternately, that these may develop secondary to chronic inflammatory processes.


If nasal polyps are suspected, in many cases the dog will need to be anesthetized so that a veterinarian can examine the palate (the upper part of the mouth cavity) in search of evidence of polyps. Another diagnostic procedure is a caudal rhinoscopy, in which a spay hook and dental mirror, or flexible endoscope (a thin rod with a small camera attached), is inserted into the nose for examination. A rostral rhinoscopy also allows for visualization, while also making it possible for your doctor to take tissue samples so that a biopsy analysis may be taken of any apparent masses. This is in order to differentiate the mass as benign or malignant (cancerous).

Additional diagnostic tests may include X-rays, computed tomography (CT) or magnetic resonance (MRI) scans in order to detect lesions of the nasal cavity, or nasopharnyx. These imaging techniques are especially useful in pinpointing other causes for the dog’s symptoms.

If nasal polyps are not found to be responsible for the dog’s symptoms, alternate diagnoses may include an obstruction in the upper airway, a neurologic disease, or a foreign body in the airway.
