Pyometra is a life-threatening infection in a dog's uterus that typically occurs 2-8 weeks after a heat cycle, predominantly affecting older dogs.
There are two types of pyometra – open and closed. Open pyometra is less dangerous than closed pyometra, as the cervix is open, allowing the infection to drain out. In closed pyometra, the cervix is closed, trapping the infection within the uterus, which can lead to a rupture and life-threatening consequences.
Symptoms of pyometra include fever, lethargy, distended abdomen, foul-smelling vaginal discharge, loss of appetite, weight loss, excessive thirst, and depression. In severe cases, vomiting and diarrhea may also occur.
