Pyometra in Dogs
Pyometra is an infection in the uterus in which the uterus fills with pus. It typically occurs 2-12 weeks after a heat cycle.
Symptoms include vomiting, listlessness, and an increase in drinking. If the cervix is open, a discharge from the vagina is seen. If the cervix is closed, no discharge is seen. Diagnosis is based on a physical exam, blood work, and x-rays.
The ideal treatment is to perform an ovariohysterectomy (spay). If the condition is not caught early, she will need to be stabilized before surgery is attempted. If the bitch must be kept for breeding, antibiotic therapy could be tried, but is not very successful.
