What is Pyometra in Dogs? 

Pyometra is an infection of the uterus, one of the reproductive organs of a female dog. This infection is most common in older females that have not been spayed and it tends to occur after a heat cycle. An increase in hormonal stimulation of the uterus during the heat period and introduced bacteria are usually the cause of pyometra in dogs. Underlying causes of pyometra include urinary tract infections and poor hygiene.

There are two types of pyometra in dogs: open and close. In cases of open pyometra, the cervix stays open and there is a characteristic vaginal discharge usually containing pus and blood. Closed pyometras occur when the cervix stays closed and are more severe because the infectious discharge accumulates within the uterus. Radiographs are usually needed to diagnose closed pyometras.
