My unspayed dog has bloody, sweet-smelling discharge. What is it?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 10 years and 3 months old | 40 lbs

About 2 wks ago my female lab mix who's 8 yrs old seemed to have had a stroke or something. Her right eye was wandering and she seemed lethargic and confused. She never stopped drinking water which we took as a blessing but she did almost die. Since then she's been leaking and I'm not sure how much of it is actually urine as it's thick, bloody, milky, and has a very strong and sickeningly sweet odor. Other than that she's getting better. Eating and gaining weight back. Any idea what may be wrong

I see that Princess Marie isn't spayed. With the discharge you are mentioning, I'd be very concerned she has a pyometra. A pyometra is an infection of the uterus that is fatal without treatment. She needs to see a vet immediately. Please take her into one now.

Female dog inactive with smelly bloody discharge. Is it pyometra?

Hello, Tisay may be having an infection of her uterus (pyometra). She should be seen by a veterinarian today and may require surgery and medications to remove her uterus. A miscarriage typically does not cause bad smelling discharge although it can, but a pyometra may be far more common to cause the clinical signs your are seeing. Best of luck and hope this helps.

Why is my unspayed female dog peeing bloody jelly-like discharge?

Has she been in heat recently? At her age with not being spayed I would worry about thisbdisxharge being from the uterus and her having an uterine infection. This can be an emergency that typically requires surgery. Often times they are weak, drinking more water, vomiting and not eating. Other options include a bladder infection which will need antibiotics. Your vet can distguish between the two and see what is needed

Why is my spayed dog bleeding with a bad smell and not drinking?

Baby Girl should be seen by a vet as soon as possible. Red discharge as you are describing could be blood due to a urinary tract infection, crystals in the urine, stones in the urinary tract, or trauma. If you notice Baby Girl straining to urinate/unable to produce urine, this is a medical emergency and she should be seen by a vet immediately. Good luck, and I hope she feels better soon!

Why is my dog bleeding heavily from her private area and not eating?

Princess likely is suffering from a urinary tract infection or possibly bladder stones, or other condition that causes bleeding of the urinary tract. This may be very painful. You will need to take Princess to a veterinarian for an exam and urinalysis. Your vet may also want to take radiographs to rule out bladderstones. She will need prescription antibiotics, pain medicine, and other treatment depending on the diagnosis. Please check her gums, and should they be white or very pale in colour, she will need to be seen by a vet right away.

My unspayed female dog has creamy white discharge. What's wrong?

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.

My unspayed dog's heat: heavy bleeding, clots, lethargy. What's wrong?

I would have Hennessey seen by a vet immediately. I would be very concerned that this heavy bleeding, lethargy, and bloating is caused by a pyometra. A pyometra is a serous infection of the uterus that is fatal without treatment. Using a physical exam, blood tests, urinalysis, and x-rays, the vet can diagnose if she does have a pyometra and can treat her for it. Should she have one, spaying her is part of the recommended treatment. Please take Hennessey into an ER vet or find a vet on call to see her now.

My dog has bloody discharge after uterine infection. What's it mean?

Thank you for using Petco Pet Education Center, formerly Petcoach if Izzy has a pyometra or uterine infection she needs to be spayed ASAP. This can be a fatal turn right on Rio Grande St. infection leading to sepsis turn left on superior and death if left untreated. While antibiotics can decrease signs It will typically not fully clear the infection, which will cotinue to recur and worsen. If Izzy has a foul smelling bloody discharge she needs to see a veterinarian as soon as possible.
