Pyometra in dogs 

  • Pyometra is common in dogs who have not been spayed. 

  • A pyometra is an infection of the uterus or womb and is an emergency which will need treatment as soon as possible. 

  • Treatment will involve stabilising your pet with fluids, checking their bloods and spaying your pet. 



  • Drinking a lot and possibly urinating more frequently 

  • Not eating 

  • Vomiting 

  • You may or may not see discharge from their back end, this depends on whether the pyometra is open or closed

  • Bloated abdomen 

  • Panting and possibly some weakness 


Animals will commonly develop a pyometra 4-8 weeks after their season, but if you notice any of these symptoms always contact your veterinarian immediately. 


If your vet suspects your dog has a pyometra then they will use ultrasound to visualise your dog's uterus, if your dog has a pyometra then their uterus will appear fluid filled. 



  • Your animal will be admitted for fluids, medical treatment and spay under general anaesthetic. 

  • Surgery is the most recognised and advised treatment for a spay, occasionally hormones are used to try and manage a pyometra but this is dangerous and not generally recommended. 


Occasionally animals who have been spayed can develop a stump pyometra which occurs when there is a small amount of uterus and also a small amount of ovary left behind after a spay, although this is rare.
