Canine Nasal Tumours: Welfare and Palliative Care

Nasal tumours in dogs cause progressive facial disfigurement, pain, and respiratory compromise, with treatment options that can extend good-quality life for many months.

Key Facts

Nasal tumours account for approximately 1% of all canine tumours; carcinomas and sarcomas are most common.
Large and medium breeds, particularly Collies, Airedales, and German Shepherds, are overrepresented.
Signs include unilateral nasal discharge (often bloody), epistaxis, facial deformity, and breathing difficulties.
Diagnosis requires CT imaging and biopsy; the extent of local invasion determines prognosis.
Without treatment, median survival is approximately 3-5 months from diagnosis.
Radiation therapy is the most effective treatment, extending median survival to 12-18 months.
Chemotherapy and surgery have limited roles; surgery alone is not recommended due to incomplete excision.
Palliative management with NSAIDs and supportive care can maintain quality of life for months.

Welfare Considerations

Nasal tumours cause a constellation of welfare impacts: epistaxis is distressing and frightening, facial disfigurement affects owner-pet relationship dynamics, and progressive airway obstruction causes chronic respiratory discomfort. Pain from local tissue invasion may be underappreciated, as dogs often maintain normal demeanour until late in the disease. Radiation therapy carries side effects including mucositis and rhinitis that require careful management during the treatment period. Palliative care focused on comfort — NSAID analgesia, humidity support for breathing, nutritional support — can maintain reasonable quality of life. End-of-life planning should begin at diagnosis, with clear thresholds identified for when quality of life is no longer sustainable.

What You Can Do

Investigate unilateral nasal discharge or epistaxis promptly — early diagnosis improves treatment options.
Discuss radiation therapy with a veterinary oncologist as the most evidence-based treatment option.
Maintain excellent nutritional support — nasal tumour dogs often have reduced appetite.
Monitor breathing comfort and discuss management options for progressive airway obstruction.
Use validated quality-of-life tools to guide treatment decisions and timing of end-of-life care.
Ensure adequate pain management is part of the treatment plan from diagnosis onwards.
