This is gross/random question but her vagina sometime smells like iron... does anyone know what this could be? She is fixed so I know it is not her period. Also, she sometimes gets this snot looking discharge hanging from her after she goes pee. I am wondering if it could be because she is a puppy and has recently been vaccinated and taken worm medication? I am not sure. It is getting better if anything, so I have not taken her to get checked yet, but every so often I get a wif.
