Lymphoma is one of the main neoplasms that affects dogs, representing 80-90% of all hematopoietic tumors and 8-9% of all tumors. In the current paper we assessed the incidence of canine lymphomas that were diagnosed in the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania) over a ten-year period (2005-2014).The epidemiological data were collected from the records of the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania) in the last decade. The investigation included dogs diagnosed with lymphoma, following necropsy analysis or assessment of biopsies or cytological samples collected by fine needle aspiration from lymph nodes. All collected specimens were analyzed for histopathological diagnosis. We analyzed the distribution of canine lymphoma in relation to age, breed and sex, as well as the proportion of each anatomical form of lymphoma. The highest prevalence of lymphoma was observed in dogs aged 6 to 9, in Mongrels, Rottweiler and German shepherd dogs, with a very small difference between males and females. 79.8% of the dogs in this study were diagnosed with multicentric lymphoma, 5.76% with the gastrointestinal form, 5.76% with the cutaneous form, 4.8% were extranodal lymphomas and 3.84% were mediastinal ones. The results we obtained are agree with the statistics cited in the research literature. Considering that canine lymphoma is a common tumor in individuals of various ages, sexes and breeds, further epidemiological reports may aid in the establishment of the main risk factors for this entity.
