Understanding Spleen Cancer in Dogs
When it comes to the health of our beloved canine companions, it’s important to be aware of potential health conditions that may affect them. One such condition is splenic mass in dogs, which can be a cause for concern. Understanding the nature of splenic masses and the risk factors associated with them is crucial in providing the best possible care for our furry friends.
Overview of Splenic Masses
A splenic mass refers to an abnormal growth or tumor in the spleen of a dog. While not all splenic masses are cancerous, one of the primary concerns when a splenic mass is discovered is hemangiosarcoma, a highly malignant cancer of the blood vessels. According to the “double two-thirds rule,” approximately 45% to 65% of splenic masses in dogs are hemangiosarcoma (dvm360). However, it’s important to note that only about 30% of incidentally found splenic masses in dogs are malignant, with the majority being benign (dvm360).
Risk Factors for Hemangiosarcoma
While any dog can develop a splenic mass, certain factors may increase the risk of developing hemangiosarcoma. Large-breed dogs are generally considered to be at higher risk, although the condition can affect dogs of any size. German Shepherds, Golden Retrievers, Labrador Retrievers, and Poodles are believed to be at the highest risk, with a suspected genetic predisposition (dvm360). It is important to note that the presence of risk factors does not necessarily guarantee the development of hemangiosarcoma, and dogs without any known risk factors can still be affected.
Regular veterinary check-ups and screenings play a vital role in the early detection of splenic masses, especially in at-risk breeds. If you notice any symptoms such as weight loss, decreased appetite, lethargy, or abdominal swelling in your dog, it’s essential to consult with a veterinarian promptly. Early detection of splenic masses, including both benign and malignant tumors, can significantly improve treatment outcomes.
By understanding the overview of splenic masses and the risk factors associated with hemangiosarcoma, dog owners can stay vigilant and provide the necessary care for their furry companions. Regular veterinary visits, awareness of potential symptoms, and prompt medical attention are crucial in ensuring the well-being of our dogs and managing any health conditions that may arise.

Diagnosis and Detection
When it comes to detecting and diagnosing a splenic mass in dogs, various diagnostic tools and symptoms are utilized to aid in the identification of this condition.
Diagnostic Tools for Spleen Evaluation
The presence of a splenic mass in dogs is typically diagnosed or confirmed using ultrasound, which allows for a non-invasive assessment. Ultrasound provides detailed images of the spleen, allowing veterinarians to evaluate the size, shape, and characteristics of the mass. This imaging technique is particularly useful in identifying the presence of tumors or abnormalities in the spleen (Vet Collection).
In addition to ultrasound, other diagnostic tools may be employed to further evaluate the spleen. Radiographs of the abdomen can provide a preliminary assessment of the spleen and surrounding structures. Chest radiographs may also be recommended to check for any signs of cancer spread. Basic blood work, including a complete blood count (CBC) and serum chemistry panel, can help identify any changes associated with the splenic mass, such as anemia or alterations in organ function (Veterinary Partner).
For a more definitive diagnosis, a solid tissue biopsy is often necessary. Needle samples may not provide a conclusive diagnosis, making solid tissue biopsy the preferred method to determine the specific type of splenic mass. However, this can only be achieved through surgical intervention, such as a splenectomy.
Symptoms and Indicators
Detecting a splenic mass in dogs may involve recognizing certain symptoms and indicators. While these signs can vary depending on the size and location of the mass, some common indicators may include:
- Sudden weakness or collapse
- Pale gums or mucous membranes
- Loss of appetite
- Weight loss
- Abdominal distension or bloating
- Difficulty breathing
- Lethargy or decreased activity levels
If you notice any of these symptoms in your dog, it is essential to seek veterinary attention promptly. Keep in mind that these symptoms are not exclusive to splenic masses and may be indicative of other health conditions as well.
Early detection is crucial for timely intervention and improved prognosis. Regular physical examinations, especially in older large breed dogs, can aid in the early identification of splenic masses. If your veterinarian suspects a splenic tumor based on physical examination findings or symptoms, they may recommend further diagnostic tests, such as ultrasound or radiographs, to assess the condition of the spleen.
Understanding the diagnostic tools and recognizing potential symptoms of a splenic mass in dogs can help facilitate early detection and appropriate treatment. If you suspect any issues with your dog’s health, it is always best to consult with a veterinarian for a proper evaluation and diagnosis.
Treatment Options
When it comes to addressing splenic mass in dogs, there are several treatment options available, depending on the specific diagnosis and prognosis. Two common approaches include surgical intervention, specifically splenectomy, and the consideration of chemotherapy.
Surgical Intervention: Splenectomy
Splenectomy, the surgical removal of the spleen, is often the primary treatment option for canine spleen cancer such as hemangiosarcoma. This procedure aims to remove the affected spleen, which may contain the tumor or mass. Splenectomy is an effective approach for benign splenic masses, as it can effectively cure the condition.
However, it’s important to note that the outlook for dogs with hemangiosarcoma after surgery alone may not be as favorable. According to the American College of Veterinary Surgeons (ACVS), survival times with surgery alone for dogs with hemangiosarcoma may be 2-3 months or less, with a one-year survival rate of less than 10% (ACVS). The main cause of mortality in these cases is often metastatic disease.
Chemotherapy Considerations
In cases where hemangiosarcoma or other malignant splenic masses are diagnosed, the use of chemotherapy may be considered as an adjunctive treatment following surgery. Chemotherapy involves the administration of specialized medications that target and destroy cancer cells throughout the body.
According to the ACVS, the addition of chemotherapy after surgery for dogs with hemangiosarcoma can potentially increase survival times up to 6-8 months. While it does not provide a cure, chemotherapy may help extend the lifespan and improve the quality of life for affected dogs.
It’s important to consult with a veterinarian experienced in oncology to determine the most appropriate chemotherapy protocol for your dog’s specific case. They will consider various factors such as the stage of the disease, overall health of the dog, and potential side effects of the medications.
Each dog’s response to treatment may vary, and regular monitoring and follow-up visits with the veterinarian are essential to assess the effectiveness of the chosen treatment plan.
By combining surgical intervention with chemotherapy, veterinarians aim to provide the best possible outcome for dogs with splenic masses, particularly those diagnosed with hemangiosarcoma. However, the prognosis for hemangiosarcoma remains challenging, and ongoing research and clinical trials are continuously exploring new treatment options to improve outcomes.

Prognosis and Recovery
After a diagnosis of a splenic mass in dogs, it’s natural for dog owners to be concerned about the prognosis and recovery process. Understanding the survival rates and potential post-surgery complications can help in making informed decisions regarding treatment options.
Survival Rates
The prognosis for dogs with splenic tumors can vary depending on several factors, including the type of tumor and the presence or absence of metastasis at the time of diagnosis. Malignant tumors, such as hemangiosarcoma, tend to have shorter survival times compared to benign tumors.
According to dvm360, the average survival time following palliative surgery for splenic masses is 1 to 3 months. However, when surgery is followed by systemic chemotherapy, the survival time can be extended to 6 to 9 months. It’s important to note that survival times can vary, and individual cases may differ from these averages.
The prognosis for dogs with hemangiosarcoma treated with splenectomy followed by chemotherapy is an average survival time of 6 to 7 months, as reported by Vet Collection. It’s essential to consult with a veterinarian to get a more accurate prognosis based on the specific circumstances of your dog’s case.
Post-Surgery Complications
Surgery, such as a splenectomy (removal of the spleen), is a common treatment option for splenic masses in dogs. While this procedure can be beneficial, there are potential complications associated with it.
Some of the post-surgery complications that may arise include:
- Hemorrhage: Ongoing bleeding could occur after surgery. Immediate medical attention is necessary if this complication arises.
- Cardiac arrhythmias: Irregular heart rhythms may be observed after surgery. An electrocardiogram (ECG) is recommended to detect any arrhythmias. Most arrhythmias resolve within 24 to 48 hours with appropriate treatment.
- Pancreatitis: Pancreatitis, often manifested by vomiting, is another possible complication following surgery. It requires medical attention and treatment.
It’s important to closely monitor your dog’s post-surgery recovery and promptly report any concerning symptoms to your veterinarian. By following the post-operative care instructions provided by your veterinarian, you can help minimize the risk of complications and support your dog’s recovery.
Remember, the information provided here serves as a general guide, and specific cases may vary. Working closely with your veterinarian will provide the most accurate prognosis and guidance throughout your dog’s treatment journey.
Ongoing Research
