Dog Splenic Tumours Emergency Recognition

Splenic haemangiosarcoma is a rapidly fatal cancer in dogs that can rupture and cause life-threatening haemorrhage requiring emergency surgery and careful welfare assessment.

Key Facts

Splenic haemangiosarcoma is most common in German Shepherds, Golden Retrievers, and Labrador Retrievers
Approximately two thirds of splenic masses in dogs are malignant haemangiosarcoma
Tumours may be detected incidentally on abdominal imaging or present with acute collapse from rupture
Emergency splenectomy provides immediate survival benefit but median survival without chemotherapy is 1-3 months
Echocardiography should assess for cardiac haemangiosarcoma before surgery

Welfare Considerations

Ruptured splenic haemangiosarcoma causes acute haemorrhage, rapid shock, and death without emergency intervention. The collapse is dramatic and distressing. Emergency surgery provides immediate welfare benefit by stopping the haemorrhage. However, the poor long-term prognosis means honest discussion about post-surgical quality of life and expected survival time is an important welfare conversation. Dogs who recover from surgery deserve excellent palliative care and maximum quality remaining time.

What You Can Do

Seek emergency care immediately for dogs showing sudden weakness, collapse, or abdominal distension
Discuss prognosis honestly with your vet before committing to emergency surgery
Request echocardiography to assess for cardiac involvement before surgery
Explore doxorubicin-based chemotherapy after recovery from surgery to extend survival
Have honest quality of life conversations throughout the post-surgical period
