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!

    It sounds like she may be coming in/out of heat. Small dogs don’t always have a significant amount of blood where you can see. Sometimes it is just a few drops here/there. She may also be experiencing a false pregnancy which is where her body thinks she is pregnant but she isn’t. Keep a close eye on her and to be extra cautious don’t let any intact males near her if you don’t want to have accidental puppies. If she starts to be lethargic, refusing to eat, or any additional weird behaviors i would have your vet take a look at her. I hope this helps!

    Yes, the vulva is normally swollen during the heat cycle. The swelling will go away when then heat cycle is over. Be aware that your dog will be able to conceive up to three weeks from the day she stops bleeding as she now is in heat. The time she was bleeding was preparing for the heat (pre-estrus). The best time to spay is about three months from the day she stops bleeding.

    Hi there. It's certainly possible that this could be a "silent" heat, as not all dogs have bleeding from the vulva during their heat cycles. It sounds like she's showing other normal signs of heat, such as vulvar swelling and standing for mating. The only way to know for sure what is going on with her heat cycles would be to see a veterinarian who deals with reproductive issues, for testing such as vaginal cytology, progesterone blood levels, etc. Without this information, it's all just a guess :)
