The study at Chennai showed prevalence of canine mammary tumours in 75 females and 5 male dogs. Among the bitches, 86.67 per cent were found to be malignant mammary tumours followed by 8 per cent mixed benign and malignant tumours and 5.33 per cent benign tumours. Among the 149 other tumours, the percentage prevalence in male and females were 42.28 and 57.72 respectively. The effects of sex on the prevalence of mammary tumours among other tumours cases reported in Chennai were significant. Intact females were mostly affected (92%) compared to the spayed dogs. Prevalence was higher in whelped dogs that had not been spayed and it was lower in dogs spayed at the optimum age.

Key Words: Canine mammary tumour, prevalence, bitch.
