Why does my female dog have a vaginal puss discharge?

Hello and welcome to Petco Pet Education Center, formerly Petcoach. A 5 month old female dog with SMALL amounts of puss from the vagina can be something called 'puppy vaginitis' which is a common condition that is resolved by having the puppy spayed. If there is a LARGE amount of puss present then a life-threatening condition called pyometra could be the cause, in which case she needs to go to a vet right away. Pyometra is very uncommon in a 5 month old puppy and most often always requires a dog to have had a heat first, so puppy vaginitis is most likely. This could also be a urinary tract infection resulting in puss from the vulva. I would have Baliey seen by your vet to be assessed, and have her spayed sometime in the next month or two. Best of luck with her!
