The study was aimed to analyze the influence of age, breed, estrus cycle and parity in the occurrence of canine pyometra and to assess the treatment of choice being followed for pyometra. For this study, case records of pyometra in dogs, presented between January 2013 to December 2017 were scrutinized and the influence of different factors on the incidence of pyometra was worked out. A total of 108 cases with the history of pyometra were presented in TVCC in period of 5 years. The pyometra observed in the middle to old age (>6 years) predominately (45.37%, mean age- 5.65 ± 0.3 years). The incidence was more in non-descript breeds (29.63%) followed by Labrador (24.07%) and Pug (15.74%). The disease was more prevalent in nulliparous dogs (81.82%) as compared to primiparous and pluriparous dogs which accounted to be 18.18%. There was history of estrus 16-60 days prior to the occurrence of disease in 74.63% dogs, of them, 17.05% (15/88) had mating history. Ovariohysterectomy (37.03%) was principle approach opted for treatment of pyometra. Other treatment opted for treatment of pyometra were antibiotics (24.07%), methergine (20.37%), PGF_2α analogue (16.67%) and mifepristone (0.93%).
