Pyometra is a serious infection that can affect female dogs, especially those that haven't been spayed. Here's how it happens:
1. Hormonal Changes:
After a dog's heat cycle, progesterone levels stay high for 6-10 weeks, thickening the uterine lining in preparation for pregnancy.
2. Uterine Lining Thickens:
If there's no pregnancy, repeated heat cycles cause the lining to thicken further, forming fluid-secreting cysts, creating an ideal environment for bacterial growth. High progesterone levels prevent the uterus from contracting, trapping bacteria inside.
3. Infection Develops:
Symptoms include vaginal discharge, increased thirst, enlarged abdomen, loss of appetite, and low energy. Pyometra can progress rapidly, from perfect health to death within 4 days, requiring urgent treatment.
4. Treatment:
Often involves surgery to remove the uterus and ovaries, which is a more complex procedure than a routine spay. Spaying your dog can actually prevent pyometra, so it's something to consider if you don't plan on breeding your dog.
