PYOMETRA

Pyometra is an infection in the uterus. 

However, most cases of pyometra are much more difficult to manage than a routine infection.



If pregnancy does not occur for several estrus cycles, the lining continues to increase in thickness until cysts form within it.

The cystic lining secretes fluids that create an ideal environment in which bacteria can grow. 
Additionally, high progesterone levels inhibit the ability of the muscles in the wall of the uterus to contract.

Pyometra may occur in young to middle-aged dogs; however, it is most common in older dogs. 


Symptom: The clinical signs depend on whether or not the cervix is open.

If it is open, pus will drain from the uterus through the vagina to the outside. 
It's often noted on the skin or hair under the tail or on bedding and furniture where the dog has laid.  Fever, lethargy, thirst, depression etc..

If the cervix is closed, pus that forms is not able to drain to the outside.
It collects in the uterus causing distention of the abdomen. 
The bacteria release toxins which are absorbed into circulation -   These dogs often become severely ill very rapidly. 
Listless, very depressed.  Vomiting or diarrhea may be present. No apitite.
A very ill female dog that is drinking an increased amount of water and has not been spayed is always suspected of having pyometra. 
This is especially true if there is a vaginal discharge or an enlarged abdomen



Treatment: Some few times antibiotics can help, but most common is to surgically remove the uterus and ovaries.
