My dog was spayed over a year ago and still has a dark red discharge and a odor.

I had my chihuahua spayed over a year ago and she has a constant dark dried discharge on her. Plus she has a foul smelling odor coming from her vagina. I have taken her to the vet numerous times and they tell me it is from her being aggressive. I do not see that as being the problem. I was wondering what else could it be?

Yikes! I'd worry about either an underlying urinary tract infection (UTI) or even a "stump pyometra." (where the small remnant of her uterus left in there - the cervix) may have an active infection. I'd recommend getting x-rays or even an ultrasound done to make sure it doesn't need antibiotics or surgery!

I am glad to see that you are a responsible pet owner and got your dog spayed.  I am also sorry to see that you may be having potential complications from this procedure.  This is a difficult question to answer without seeing your dog.  I would like to know more information.  How does your dog feel? Is she acting normal?  How is her appetite?  Does her vulva become swollen seasonally?
In this case I would also consider a second opinion.  It never hurts to have a second set of eyes on a unresolved problem.
Please keep me posted.
Thanks,
Dr Vicksman
