My dog has dark vaginal discharge after tick fever and heat cycle

I recommend to have Izzy examined by her veterinarian today. Dogs who are in heat will have a bloody discharge that is usually very light colored. Infections in the uterus can be severe and even fatal if not treated quickly so it’s best to have her checked for this today. Cancer and vaginitis are also possible. Best of luck and please feel free to post any additional questions.

If your dog isn't [spayed](https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/), this could be a heat cycle. Or it could be a very serious condition known as [pyometra](https://www.petcoach.co/dog/condition/pyometra/), which means infected uterus. Especially if she had her heat cycle a couple of months ago, and if she's lethargic or has a fever you need to take her in to a veterinarian to be examined tonight. If she is spayed, this could be several things. She could have a [urinary tract infection](https://www.petcoach.co/article/5-signs-of-urinary-tract-disease-in-dogs) and you're seeing her leak blood-tinged urine. I hope not, but depending on her age there could be cancer in the urinary tract that's causing bleeding (blood doesn't always look bright red). Very occasionally spayed dogs will continue to bleed if a piece of an ovary was left behind. Get her checked out by your veterinarian as soon as possible to figure out what's going on.

Poor giril. This looks like dark serosanguinous fluid, which could indicate an infection of her uterus. This often occurs post-labor or post-menstrual cycle. I would highly recommend taking Willow to your local vet to have her blood tested and vitals checked (temperature especially) to make sure she is ok. Often-times if there is an infection of the uterus (pyometra), the pet will have a fever, decreased appetite, sometimes vomiting and loose stool. I do hope that your pet Willow will be ok moving forward. Best wishes and take care!

This is not normal. Blood around the vulva can be a sign of a urinary tract infection or a uterine infection or hemorrhage. I recommend you make an appointment with your veterinarian for an exam so the cause for this can be established and treated.

Thank you for submitting your question regarding Nymeria. The flow can vary throughout a dog's heat cycle and from one cycle to the next. As long as she is eating, drinking and acting like herself, it is most like a normal variation. If the flow does not decrease soon or she starts to act ill, then she will need to see a veterinarian. If the discharge starts to look like pus, this can be a sign of a serious uterine infection. In this case, she would need to seen right away. I hope this information helps!

It's not normal for a dog to have a black bloody discharge with a bad smell during her heat, and I would have Pip seen by a vet right away. I would be very concerned that this dark blood and bad smell could be indicative of an infection of the uterus. Have her seen by a vet ASAP for a health check.

Uh-oh, this is quite concerning. This could be vaginitis, but probably is a uterine infection (pyometra, open). This is an emergency and she needs to be seen by a vet preferably today. Your vet will give Daisy a thorough exam, and then probably will want to do an x-ray to verify his diagnosis. Treatment is surgery to remove the uterus with all the pus contained. Antibiotics sometimes work, however that would only delay the surgery as she will have another uterine infection when she has her next heat. Please take her to your veterinarian ASAP.
