I'm so very sorry to hear that you lost your Lusi. Unfortunately, pyometra always causes toxins and bacteria to get into the blood stream, so if Lusi had a pyometra, we know she had infection in her bloodstream. Often dogs with a pyometra are sick (fever, vomiting, lethargic) from the infection in the bloodstream which makes surgery even more dangerous, but the only option to try to save them. Some dogs survive with surgery, but some do not if the infection was already too severe, but often we do not know which ones will survive and which ones will not. I have attached a handout below with more information on pyometra. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=603 It sounds like you and your vet did everything possible to save Lusi, but she was likely just too sick from her pyometra. Again, I'm so sorry for your loss.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am sorry that Lusi is sick! Most dogs with a pyometra are systemically sick. The bacteria most commonly associated with a pyometra produces toxins that can influence the entire body but most commonly the kidneys. The puss in the uterus can cause the dog to become septic as well. We usually can tell based on blood work (white blood cell count and kidney values) how sick the dog is and if they will survive post operatively. Most dogs do well after removing the uterus. Dogs with high kidney values and dogs where the uterus has ruptured tend to not do well. I hope this helps and I wish Lusi the very best!
