Plain-English summary
A 10-week-old miniature dachshund was brought to the vet because it suddenly became weak. Tests showed that the dog had serious heart issues, including rapid heartbeats and fluid buildup in the chest and abdomen. Despite attempts to drain the fluid and provide oxygen, the dog did not improve and sadly passed away shortly after arriving at the clinic. A closer examination revealed that the dog had primary cardiac lymphoma, a rare type of cancer affecting the heart, which is unusual in such young dogs.

Abstract
A 10-week-old miniature dachshund presented with acute onset of weakness. Electrocardiography showed sustained ventricular tachycardia, and thoracic and abdominal radiography revealed pleural and peritoneal effusion. Echocardiography revealed severely hypokinetic left and right ventricles. Thoracocentesis and abdominocentesis and subsequent transfer to an oxygen chamber yielded no clinical improvement, and the dog died about 1 hr after admission. Gross examination of a longitudinal section through the entire heart revealed poorly demarcated focal or patchy areas of grayish-white tissue infiltrating extensively into the myocardium. Histologically, these lesions were consistent with infiltrative proliferation of neoplastic lymphoid cells. Immunohistochemical staining confirmed the diagnosis of primary cardiac lymphoma (PCL) of T-cell origin. There have been no previous reports of such young dogs with PCL.
