Pyometra

Pyometra should be the number one reason to spay your female dog. Aside from preventing unwanted litters.

WHAT IS PYOMETRA?

A Pyometra is an infection of the uterus and the word literally means ‘Pus in the Womb’. It is a secondary infection that occurs as a result of hormone changes in the females reproductive tract.
When a dog is in season/heat, the white blood cells, which normally protect against infection, are inhibited from entering the uterus.

If a pregnancy does not occur for several consecutive oestrus cycles (season/heat), the uterine lining continues to increase in thickness until cysts often form within the tissues. This is known as ‘Cystic Endometrial Hyperplasia’.
The thickened, cystic lining secretes fluids that create an ideal environment for bacteria to grow in.

Additionally, high progesterone levels inhibit the ability of the muscles in the wall of the uterus to contract and expel accumulated fluids or bacteria. The combination of these factors often leads to infection.

CLINICAL SIGNS

Pyometra usually occurs two to eight weeks after the last season/heat.
Pyometra can affect any female dog at any age but is most common in older dogs.
