Abstract:
Canine mammary tumours are the most commonly occurring tumours in dogs. The present study was aimed at determining the epidemiological characteristics of canine mammary tumours that were reported in and around Wayanad, Kerala over a period of one year (August 2017 to June 2018). The study included 40 excisional biopsy samples of intact female dogs presented to Teaching Veterinary Hospital, Pookode, Kerala. Age wise analysis revealed that highest risk of developing mammary tumours was seen in the age group of 7-9 years with the mean age of 7.04±1.90 years. Data on breed wise occurrence showed highest number of cases in Labradors followed by German shepherds. The majority of the tumours were having malignant features histologically (92.5 per cent) and three tumours were identified to be benign. Incidence was more with intact female dogs and the caudal and inguinal mammary glands were more affected. Highest number of tumours were epithelial type (simple carcinomas) followed by mixed tumours. Among malignant tumours, solid carcinomas were the most frequent type followed by ductal carcinomas and in benign tumours, adenomas were the most common type of tumour.
