A 1 year old Great Dane bitch was presented with multiple, pedunculated masses of varying sizes. On clinical examination, the masses were soft, pliable and revealed both pigmented as well as un-pigmented skin coat. Histopathologically, all the tumour masses were characterized by mild epidermal hyperplasia along with aggregates of melanin pigments in the dermis. The dermal collagen was moderately hyperplastic and arranged as wavy bundles often containing focal aggregates of melanin. The cases of melanoma in dogs have been reported by many earlier workers but the unusual occurrence of spontaneous multiple cutaneous melanomas in a one year old dog as in the present case appears to be very rare and not have been reported earlier.

Key Words: cutaneous, cytology, Great Dane, hyperplastic, melanoma
