We conducted a large retrospective study to establish a registry of canine tumours diagnosed in Slovenia over a 20-year period and to analyse their incidence rate and some epidemiological characteristics. In the study, we analysed the results of histopathological examinations of biopsies and samples from the necropsies of dogs submitted to the Institute of Pathology, Wild Animals, Fish and Bees of the Veterinary Faculty, University of Ljubljana between 2000 and 2020. Malignant tumours predomi-nated (58.81%), followed by benign tumours (37.17%); 4.02% of tumours were of un-specified biological behaviour. Tumours were most frequently found in the skin and subcutaneous tissue (57.83% of all tumours), the mammary gland (14.07%) and the haemolymphatic system (6.63%). The most frequently diagnosed tumours were mast cell tumour (14.17%), mammary (adeno)carcinoma (10.02%), cutaneous histiocytoma (7.34%) and cutaneous/subcutaneous lipoma (6.92%). 51.69% of dogs with tumours were female, and 48.17% were male. Tumours were most common in Golden Retrievers (4.86%), Boxers (4.72%), German Shepherds (4.66%) and Labradors (4.27%), and were the most common between age of 8 and 11 years. In 151 dogs (2.03%) multiple tumours of different types were detected at the same time. The results of our study are mostly comparable with the results of other similar studies.
