My 9 month old female miniature dachshund was emitting a metallic odor from her back end yesterday. I noticed it, did some google-ing, and shortly after the smell disappeared. My research concluded that it might be her anal glands. But I can’t understand why the smell disappeared (and as of this morning had not returned). She has exhibited no other signs or symptoms (no scooting on the floor, no problems going to the bathroom, acting perfectly normal)

As the mystery continued, we were walking outside to use the potty before taking a drive. After peeing, we got into the truck with her on my lap. I noticed she has made a wet spot on my pants. Assuming it was just some urine from her potty trip, I used a towel to wipe me and her off. That’s when I noticed that coming from her vulva was a thick, milky, yellow color liquid that was accompanied by a fishy smell. This led me to think that maybe she has a case of vaginitis. As the day progressed, both smells and the discharge disappeared. And as of this morning, no trace of either can found. I was already planning on taking her to the vet on Friday, should I take her in sooner? She just finished her first heat last week and I am planning on finding out this week when we can get her fixed.
