The aim of this study was to investigate the incidence and anatomic location of canine cutaneous tumors and the sex, age, and breed distribution of dogs with skin tumor. A total of 2,172 tumor samples submitted for histopathological diagnosis from local animal hospitals during 2005-2018 were retrieved.
