This is indicated by the Illustrious Official College of Veterinarians of Valencia (@ICOVValencia), which indicates that the only possible and totally safe preventive measure when avoiding it is the female sterilization. The pyometra is a dreaded disease due to its serious consequences, although if it is detected in time the prospects and the survival rate of the animal improve.
It is a uterine infection, so it only affects bitches, and can arise at any time after the first heat, although it can generally be suffered by adult females who have completed four or five years of life.
The infection manifests itself in the last weeks of heat, when the bleeding stops and increase progesterone levels in the body. Veterinarians explain that the high concentration of this hormone makes the invaluable contractions that the uterus performs naturally decrease, favoring the development of infectious bacteria that end up affecting the endometrium, the inner layer that covers the reproductive organ and that is essential for the maintenance of pregnancy.
Symptoms That Your Dog Needs Immediate Medical Attention
There are two types of pyometra that can affect your pet: the open, which is easily recognized by the bloody vaginal secretions with pus that the bitch expels; and the closed, the most dangerous, because the absence of these secretions is more difficult to detect and, in addition, the infection does not have any “exit route” and its spread to other organs is even faster.
If the dog is not seen on time, the danger of serious complications, such as peritonitis, kidney failure or a generalized infection of the whole body (septicemia), increases with each passing minute. If you detect these types of visible manifestations, which indicate a possible infection, and your dog has symptoms of lethargy, does not want to eat or even appears to have a feverchills or shaking) it is essential to go to a veterinary clinic as soon as possible.
Regarding the closed pyometra, the periodic reviews, which include a complete physical examination, an ultrasound, a laboratory test and, in case of suspicion, a cytology; it is the best preventive measure to be able to detect it.
Depending on the extent of the infection, the veterinarian may opt for a less aggressive treatment, based on antibiotics and a uterine lavage, or directly by a surgery that involves removal of the uterus and ovaries, thus ending any reproduction option.
