Abstract Cutaneous lesions, especially skin tumors in dogs, are among the most common lesions this animal species. The aim of study was to identify types canine cutaneous determine absolute and relative frequency each type lesion, anatomical locations, mean age, as well gender breed distribution. examination included all samples dogs obtained by surgical biopsy veterinary clinics examined at Laboratory Department Pathology Faculty Veterinary Medicine, University Belgrade from 1 st January 2011 July 2021.
