What Is Pyometra?
Pyometra is an infection of the uterus that typically occurs in older, unspayed female dogs. It can develop after a heat cycle when hormonal changes make the uterus more susceptible to bacterial infection.
Types of Pyometra
There are two main types of pyometra:
- Open Pyometra: The cervix remains open, allowing pus to drain from the uterus. This type is easier to detect due to visible vaginal discharge.
- Closed Pyometra: The cervix is closed, trapping pus inside the uterus. This type is extremely dangerous as the uterus can rupture, leading to life-threatening complications.
Symptoms of Pyometra
If your dog is suffering from pyometra, you may notice:
- Vaginal Discharge: Particularly in open pyometra.
- Lethargy: Your dog may seem unusually tired, weak, or unresponsive.
- Loss of Appetite: Refusal to eat is a common sign of illness.
- Increased Thirst and Urination: Due to toxins affecting kidney function.
- Abdominal Swelling: In cases of closed pyometra.
Risks of Untreated Pyometra
Pyometra is a medical emergency. If left untreated, it can lead to:
- Sepsis: A systemic infection that can cause multi-organ failure.
- Uterine Rupture: Leading to peritonitis (severe internal infection).
- Kidney Failure: Permanent damage from circulating bacterial toxins.
Diagnosis and Treatment
If you suspect your dog has pyometra, contact Central Valley Veterinary Hospital immediately. Diagnosis usually involves physical exams, bloodwork, and ultrasound imaging.
The standard and most effective treatment is emergency surgical removal of the infected uterus (spay). While antibiotics may be used as supportive care, surgery is necessary to remove the source of infection.
Prevention
The only certain way to prevent pyometra is to spay your dog. By removing the uterus when your dog is healthy, you eliminate the risk of this life-threatening infection entirely.
Conclusion
Pyometra is a critical condition that requires rapid intervention. Early diagnosis and surgery offer the best chance for a full recovery. If your unspayed female dog shows any sign of lethargy or unusual discharge, call Central Valley Veterinary Hospital at (209) 239-2547 immediately.
