Influence of some factors on the incidence of pyometra in the bitch

Abstract

The aim of the present study was to determine the influence of breed, age, season, mating, pregnancy, progestin contraceptive treatment and the onset time of the disease after the last heat on the incidence and epidemiology of canine pyometra in Bulgaria. The investigation included 217 bitches suffering from pyometra. We found that the disorder was most often observed in 7-year-old, mixed breed bitches, most frequently in September and 4 weeks after the heat.
