The word Pyometra comes from the Latin language and means a pus-filled uterus. Usually, it is seen in females dogs that are over 5 years old, but the risk of this condition goes up with age. It the uterus is not removed, the dog will most assuredly die.
This will be done surgically, by your vet. Most of the time, an imbalance of hormones, specifically Progesterone, causes an overactive uterus lining. Accumulation of these secretions collect in the uterus cavity and could cause distention. It is possible for a secondary infection from bacteria to make it`s way through the vagina and develop, though a number of organs diagnosed as having Pyometra have been found to be sterile.
It is most commonly seen one week to three months after the dog comes into heat, but can be seen at any point in the cycle. It can also accompany Pseudocyesis, or False Pregnancy, though there`s not enough proof to establish a link between these hormone dependent diseases. It can be present in females that have not copulated for an extended time or females that have just had a litter.
It can be diagnosed by the dog`s recent heat history as well as clinical symptoms and signs. Common symptoms include; drinking excessive amount of water; loss of appetite; diarrhea and vomiting. You may also see listlessness, abdominal swelling and vaginal discharge, which normally has a very foul smell.
The only way to really prevent Pyometra is to have your dog desexed. Once it is contracted, the uterus will have to be removed by surgery and there are always risks with surgery. Take into consideration your dog`s age, medical history and any condition she may have, such as heart disease.
