Abstract: Squamous Cell Carcinoma (SCC) was diagnosed in 33 dogs based on gross, cytological and histopathological examination of samples from tumour suspected masses. The highest incidence was recorded in Spitz, Non-descript and Labrador breeds, in male dogs, in dogs of age group more than 5 years and in head in breed, sex, age and in location wise analysis of SCC. Cytologic examination revealed round to caudate neoplastic cells containing round to oval nuclei, tadpole cells, anisocytosis and anisokaryosis. Histopathological examination revealed solid sheets of neoplastic cells with vesicular nuclei containing prominent single to multiple nucleoli and eosinophilic cytoplasm, keratin pearls, cell nests and mitotic figures.
