Pyometra is a serious and potentially life-threatening infection of the uterus in female dogs. Treatment for pyometra typically involves surgery to remove the infected uterus, as well as antibiotic therapy. Enrofloxacin is a type of antibiotic that is commonly used to treat pyometra in dogs, though other antibiotics may be used depending on the severity of the infection. Treatment of pyometra should be done as soon as possible to reduce the risk of complications and save the life of the dog.
