Pet's info: Dog | Labrador Retriever | Female | unspayed | 10 months and 21 days old | 60 lbs
Hello. My 10 month old red Labrador retriever has recently finished her first heat cycle. However since then her vulva has changed from pink to black. I’m concerned. When she was at the peak of her cycle it swelled A LOT and turned bluish like a bruise. Now it’s black.

Thank you for submitting your question regarding Skyler. The vulva will stay larger after the first heat cycle and can change in appearance. The mammary chains will also stay larger as compared to before her first cycle. The vulva still looks normal to me, but she should see her veterinarian if you are concerned. I hope this information helps!
