My dog has a discharge from her vulva. Is this a sign she is going to go into her first heat soon?
The discharge pictured is a greenish-yellow, so I'm concerned that Athena may have [pyometra](https://www.petcoach.co/dog/condition/pyometra/), which is a potentially deadly infection of the uterus that can happen in dogs. A tiny bit of white vulvar discharge can be within normal variations for puppies (called a "puppy vaginitis"), but a greenish-yellow discharge is never normal. I recommend having Athena evaluated by her vet or an emergency vet right away. Your vet will likely [recommend spaying](https://www.petcoach.co/article/spay-and-neuter-basics-for-dogs-and-cats/) Athena right away if they [diagnose a pyometra](https://www.petcoach.co/article/pyometra-infections-of-the-uterus-in-dogs/), as this removes the pus-filled uterus and ovaries. Spaying stops the heat cycle, eliminates the risk and cost of unwanted breeding, reduces the risk of breast cancer, and prevents the a pyometra from developing.
