My dog in heat has a ball-like lump from her vagina. Is it normal?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 8 months and 5 days old | 40 lbs

My dog has been on her period for about two weeks now , we just went to check if she was still bleeding and she laid on her back , and a ball type thing coming out of her vagina . She doesn't seem in pain and she's not lethargic.

This is uite common and s due to swelling of the tissue under hormonal influences. If it remains small and not exposed to trauma/drying out it should resolve as the heat ends; neutering is recommended as this is likely to get bigger with each heat cycle and makes both breeding and labor/delivery both difficult and risky

While this doesn't look totally normal it does look like the swelling is near a superficial blood vessel and it may not be harmful. If the area starts to seem firm again, if it seems hot or painful, if it increasing in size, or if it is not resolving once Indi goes out of heat I'd recommend having a vet take a look.

There are several possibilities.but I assume It could be a vaginal prolapse, or even a bladder prolapse. If it only happens during her heat cycle then it is likely hormonally responsive. If it becomes difficult for her to urinate or if it prolapses any more dramatically then she really should be seen immediately. Best of luck and thank you for using Pet Coach.

My dog is in heat and has a growth near her vulva. Should I worry?

Thank you for submitting your question regarding your dog. Her swollen vulva and the blood tinged discharge are consist with her heat cycle starting. However, the lesion in the pictures is abnormal. She could have traumatized herself by licking. If there is tissue protruding from her vagina, then I worry about a prolapse. If the area enlarges or seems to bother her, then she will need to see her veterinarian. I hope this information helps!

My dog's vulva is swollen and hanging out during heat. Is this normal?

Thank you for submitting your question regarding Athena. Your pictures are a bit fuzzy, but she does appear to have tissue protruding from her vulva. This may be a vaginal prolapse. She will need to see her veterinarian to confirm this suspicion. If this is the case, it will likely repeat with each subsequent heat cycle unless she is spayed. In the meantime, prevent her from licking the area. I hope this information helps!

My dog's vulva is very large and swollen during heat. Is it normal?

Yes, swelling of the vulva is normal during a heat, and it can get large especially if Poke already has a relatively large vulva. It can also be caused by an allergic reaction or an infection. It's always good to have it checked out by a vet just to be safe. I hope this helps!

Dog still swollen after heat, discharge & stomach lump. Is it normal?

Tina may have a uterine infection which could be life threatening. She should not have a discharge, nor knots nor should her vagina still be swollen. Please make an appointment with your veterinarian for an exa. Your vet may want to do xrays to visualise her uterus and blood tests to see whether her kidneys are healthy. A uterine infection can cause kidney failure and sepsis as well as death, if not treated. Usually the treatment is ovariohysterectomy (removal of the uterus and the ovaries).

Is it normal for my dog to obsessively lick her swollen vulva in heat?

It is normal during a heat cycle for the vulva to become very swollen. She is probably licking constantly to clean off and remove the bloody discharge that is coming out. She is just trying to keep herself clean. They can bleed pretty heavily for part of the heat cycle.

My dog's heat cycle is lasting weeks. Is her swollen vulva normal?

I would not be overly concerned about the single episode of vomiting/hard stool and would advise a bland diet of chicken and rice for 2-3days to see if the bowel issue resolves. I would howver be concerned about a heat cycle that has persisted for 7weeks+ and would recommend a check up with your vet tomorrow to rule out infection or other medical complications. I would recommend neutering her unless you have a need to breed from her in at the next heat cycle as excessive blood loss could become a significant issue with each cycle

My small dog's vulva is very swollen during heat. Is it a prolapse?

Thank you for submitting your question regarding Tootsie. I recommend that she sees her veterinarian. The vulva will swell with heat, but you want to ensure there is not a complicating factor such as a vaginal prolapse starting. I hope this information helps!
