The prognosis in 35 cases of canine mammary neoplasms (CMNs) was studied on the basis of their TNM staging and histologic grading. Based on TNM staging, animals were graded as having good, guarded and poor prognosis. The deaths recorded in one year follow-up period in these grades were 25%, 33.33% and 73.6%, respectively. The tissue samples were subjected to histopathological examination after surgery and on the basis of severity of malignancy, tumours were assigned grade-I, II and III. The deaths recoded in grade-I, II and III were 0%, 42.10% and 72.72%, respectively. These results suggested that both TNM staging and histologic grading may help in predicting the prognosis and may be done as a routine for the better management of canine mammary tumour cases.
