Abstract:
A retrospective study on the occurrence of mammary neoplasms in dogs presented to the Small Animal Unit-Surgery at the Teaching Veterinary Clinical Complex, RIVER, Puducherry was carried out for the period from January 2013 to December 2017. Out of 11,423 canine cases referred, 77 cases (0.67%) had mammary gland neoplasms. The occurrence of mammary neoplasms in dogs for the study period varied from 0.54% to 0.78%. Age-wise, the proportionate occurrence was highest in dogs aged above 6 years to 11 years (46/77, 59.74%) followed by those aged above 11 years to 14 years (17/77, 22.07%) and least in dogs aged 2 years to 6 years (14/77, 18.18%). Breed-wise, although the highest occurrence was recorded in the mongrels, when grouped together, the proportionate occurrence was higher in the purebreds (46/77, 59.74%) compared to the mongrels (28/77, 36.36%) and crossbreds (3/77, 3.9%). Among the purebreds, the highest number of cases were recorded in Spitz (11/46, 23.91%), followed by Labrador (8/46, 17.39%), German shepherd and Great Dane (7/46, 15.21%, each), Doberman (4/46, 8.49%), Boxer and Dachshund (3/46, 6.52% each), Pug (2/46, 4.37%) and Rottweiler (1/46, 2.17%). Of the 77 cases, 75 were recorded in females and two in males. Majority of the cases were recorded in intact dogs (69/75, 92%) compared to the spayed (6/75, 8%) animals.
