What are the clinical signs of a dog with pyometra?
The clinical signs depend on whether or not the cervix is open. If it is open, pus will drain from the uterus through the vagina to the outside. It is often noted on the skin or hair under the tail or on bedding and furniture where the dog has laid. Fever, lethargy, anorexia, and depression may or may not be present. If the cervix is closed, pus that forms is not able to drain to the outside. It collects in the uterus causing distension of the abdomen. The bacteria release toxins which are absorbed into circulation These dogs often become severely ill very rapidly. They are anorectic, very listless, and very depressed. Vomiting or diarrhoea may be present. Toxins from the bacteria affect the kidney’s ability to retain fluid. Increased urine production occurs, and the dog drinks an excess of water. This occurs in both open- and closed-cervix pyometra. How is it diagnosed? Dogs that are seen early in the disease may have a slight vaginal discharge and show no other signs of illness. Howe
