Learn about pyometra in dogs, a serious uterine infection. Discover symptoms, risks, and treatment options. Animal Medical Center.
Pyometra is a serious and potentially life-threatening uterine infection that affects unspayed female dogs. At Animal Medical Center of Pleasanton, we're here to help you understand this condition and provide the best care for your pet.
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 discharge.
Closed Pyometra
The cervix is closed, trapping pus inside the uterus. This type is more dangerous and requires immediate medical attention.
Symptoms of Pyometra
If your dog has pyometra, you may notice:
Vaginal Discharge
Especially in cases of open pyometra.
Lethargy
Your dog may seem unusually tired or weak.
Loss of Appetite
Refusal to eat is common.
Increased Thirst and Urination
Due to kidney stress.
Fever
Your dog may have an elevated body temperature.
Risks of Untreated Pyometra
If left untreated, pyometra can lead to:
Sepsis
A life-threatening infection that spreads throughout the body.
Uterine Rupture
The uterus may burst, causing internal infection.
Kidney Failure
Toxins from the infection can damage the kidneys.
Diagnosing Pyometra
If you suspect your dog has pyometra, contact Animal Medical Center of Pleasanton immediately. Diagnostic tests may include:
Physical Examination
To check for abdominal swelling or tenderness.
Blood Tests
To assess infection and organ function.
Ultrasound
To visualize the uterus and confirm the diagnosis.
Treatment Options
The most common treatment for pyometra is surgery to remove the infected uterus (spay). In some cases, antibiotics and supportive care may be used, but surgery is often the safest and most effective option.
Preventing Pyometra
The best way to prevent pyometra is to spay your dog. Spaying removes the uterus, eliminating the risk of infection. If you have an unspayed dog, monitor her closely after heat cycles for any signs of illness.
Prevention Tip: Spaying your dog not only prevents pyometra but also reduces the risk of other reproductive health issues and certain types of cancer.
