My dog's vaginal discharge stopped. Is it metritis or pyometra?

Updated On September 23rd, 2025

My dog was having a brown discharge from her vagina from many days but I thought she was pregnant so it was normal but took her to vet yesterday and he told she is not pregnant and is suffering from metritis and gave antibiotic and said to wait for 5 days and if she doesn't improve then it will be pyometra.today in morning discharge has stopped.so I don't understand is it metritis or pyometra?also metritis occurs after pregnancy so is my baby suffering from closed pyometra now or metritis?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! How old is your dog? As dogs age there are chronic changes to the uterine lining, it becomes thickened and sometimes even cystic. Metritis just means inflammation of the uterine lining and there are many causes most of which have nothing to do with pregnancy. If she had purulent discharge from her vulva that indicates an infection. A pyometra means infection (puss) in the uterus. If she responded to antibiotics I would assume she has a pyometra. My best advice is to have her spayed. It is the best thing for your dog. If she had discharge then the pyometra is open. If there was no discharge it is considered closed. I wish you the best!
