PYOMETRA is an infection of the uterus (womb) which is a common condition in older female dogs that have not been spayed, but can occur in un-spayed dogs of any age.
Occasionally we see cases occurring in cats.
What are the signs of pyometra?
Pyometra is of course, only seen in females since males do not have a uterus. It is more common in older females (above six years of age) but can be seen at any age. The signs usually develop around six weeks after the female has finished bleeding from her last season, but in some cases the bitch appears to have a prolonged season.
Early signs that you may notice are that your dog:
- Licks her back end more than normal
- Is off colour
- Is off her food
- Drinks more than normal (and will probably urinate more)
These signs will progress and you may see:
- Pus (yellow/red/brown discharge) from her vulva
- She may have a swollen abdomen
- Vomiting
- Collapse
If left untreated signs will worsen to the point of dehydration, collapse and death from septic shock.
Diagnosis
Your vet will probably suspect your dog has pyometra based on your description of the signs and from their examination of your pet. They may suggest procedures such as ultrasound and blood tests to confirm the diagnosis, rule out other possible causes and to check that your pet is well enough to undergo treatment.
Treatment
The treatment of choice for pyometra is surgery to remove her uterus as soon as possible. The operation is essentially the same as a routine spay, however there is more risk involved and a higher chance of complications when the operation is being carried out on a sick pet. Your dog will also be given intravenous fluids (a drip), antibiotics and pain relief.
