Splenic Masses in Dogs

This week’s segment features Piper the 7 year old goldendoodle!! 🐕 Piper came to us with some non-specific clinical signs and after some diagnostic testing Dr. Emerson identified that Piper had a mass growing on her spleen. The spleen plays an important role in filtering blood and supporting the immune system, but it can also develop enlargement or masses that may become serious or life-threatening. Splenic masses are often discovered during abdominal ultrasound, sometimes after a pet shows concerning symptoms and other times incidentally during routine imaging. Because these masses can bleed suddenly, early detection is critical.

Dogs with an enlarged spleen or splenic mass may show vague or intermittent clinical signs, including lethargy, weakness, decreased appetite, abdominal distension, pale gums, collapse, or sudden episodes of weakness caused by internal bleeding. Unfortunately, it’s not always possible to determine whether a splenic mass is benign or malignant based on imaging alone, which is why surgery is often recommended.

A splenectomy, or removal of the spleen, is the best way to both treat the condition and obtain a definitive diagnosis. During surgery, careful monitoring, blood support if needed, and advanced surgical techniques help minimize risk and maximize safety. After surgery, we focus on pain control, supportive care, and close monitoring to ensure comfort and a smooth recovery. Many dogs recover very well and experience a significant improvement in energy and quality of life once the diseased spleen is removed. With prompt care and thoughtful postoperative management, splenectomy can be a life-saving procedure that allows dogs to return to happy, comfortable lives. After Piper’s splenectomy she was back to her normal, happy, bouncy self!
