A pyometra is an infection of the uterus that is fatal without treatment. Signs of it include excessive drinking, abdominal distension, lethargy, anorexia, vomiting, frequent urination, and potentially discharge from the vulva (known as an open pyometra). In a closed pyometra, there is not discharge due to the cervix being closed, and if the dog isn't treated quickly, the uterus will rupture. If you suspect Abby has a pyometra, you need to take her into a vet immediately for treatment.
