Veterinary Diaries #1: Pyometra 

10-year-old FS Chihuahua presented with lethargy, fever, and brown discharge from the vulva. Top differential: Pyometra 

Pyometra: Life-threatening infection of the uterus.

The only way to be absolutely certain that this will not occur in your female dog is to spay her. The only treatment for a pyometra is an ovariohysterectomy. A pyometra is 100% preventable, please help spread the word of how important fixing your animal is! 

A 2# infected uterus was removed from a 9# dog. The dog was treated surgically and also with IV antibiotics. Unfortunately, she made it through the surgery but not the recovery process. I have attached first the pyometra uterus and what the uterus should look like. Can you imagine how painful this would be?
