Splenomegaly in dogs is frequently diagnosed in veterinary practice. Establishing its morphological substrate is of major importance in choosing the therapeutic course and establishing the prognosis. The current study analyzed 194 dog spleens (190 surgically removed), submitted to the Pathology department, between August 2005 and October 2020. Macroscopic, cytological and histopathological examinations were performed. According to our results, localized/asymmetric splenomegaly represents 78.35% of the total cases examined. Splenomegaly was diagnosed mainly in mixed-breed dogs (22.68%), among the purebreed dogs the most affected being those of medium and large size, such as German Shepherd (11.86%) and Rottweiler (10.3%). Old age is a risk factor, 51% of the subjects being over 10 years old; 53% were males and 47% females. In 55% of all cases the splenomegaly had a non-neoplastic substrate, in 45% being represented by neoplastic processes. The most frequently diagnosed tumor was hemangiosarcoma (50.57%); the most common non-neoplastic diseases were hematoma (40.19%) and splenic congestion (26.17%).
