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
