Understanding Large Abdominal Masses in Dogs

Discovering a large abdominal mass in a dog can be alarming for any pet owner. While it is natural to worry, understanding the potential causes, symptoms, and treatment options can empower you to make informed decisions about your dog’s health.

What is an Abdominal Mass?

An abdominal mass is an abnormal growth in the stomach area that may arise from organs such as the liver, spleen, intestines, or even surrounding tissues. These masses can vary significantly in size and may be benign (non-cancerous) or malignant (cancerous).

Common Causes of Abdominal Masses

Benign Growths
- Lipomas: Fatty tumors that are generally harmless.
- Cysts: Fluid-filled sacs that may grow over time but are typically non-threatening.
悪性腫瘍
- Hemangiosarcoma: A common cancer affecting the spleen.
- Lymphoma: Affects lymph nodes and can spread to the abdomen.
- Carcinomas: Tumors arising from epithelial tissues of internal organs.
Other Causes
- Abscesses: Infections that lead to pus-filled pockets.
- Organ Enlargement: Conditions like liver disease can mimic mass growth.
