It has been reported that one dog in twenty is affected, sooner or later, with some form of neoplasm. The causative factors of tumours in dogs are not fully known, but possible causes have been provided through epidemiological studies, and some known causes have been demonstrated by testing specific etiological agents, which include heredity, hormones, congenital factor, trauma, dietary carcinogens, viruses, irradiation, parasites, transplantation of intact tumour cells and carcinogens. It is concluded that the tumour occurrence in dogs is very frequent. Transmissible venereal tumours and mammary gland tumours are the most common ones, followed with the skin tumours and tumours usually occur in adult dogs of 6 to 10 yr of age.
