My dog shows heat signs, male sniffing, but no blood. Is she okay?

If Luna has a blood tinged discharge and your male dog is showing an increased interest in her, it is likely she is in heat and possible just very early stages and this is why her vulva isn't swollen. You can read more about the heat cycle in this article: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952188 (it is about false pregnancy but gives a good idea of the stages of the cycle). If, however, you think it is possible the blood could be in her urine/she is having urinary accidents/asking to pee more frequently then a vet visit is recommended.

Vaginal swelling is itself a sign of estrus/heat even without discharge. If it is the first season it may be that you won't notice any discharge at all. It is actually possible that the estrus is over already and vaginal swelling will go down in the next week time.

With any new reproductive symptom out of the norm for your pet, it is best to have a vet take a look, especially if the symptoms persist, Tinkerbell continues bleeding, or if she seems otherwise ill or in distress. A vet check in person can help rule out any issues such as infections, hormonal problems, or other related issues that may be causing the change. If you're having trouble affording care, this site may help give you some options to make it more affordable if you need to bring Tinkerbell into your vet: https://www.humanesociety.org/resources/having-trouble-affording-veterinary-care

Yes, it is possible that Peanut is in heat for the first time, as dogs may not always have obvious bleeding during heat. If she cleans herself very well, she may be licking up any bloody discharge. To be safe, I would keep her away from any intact dogs, and do not allow her out into the yard unsupervised. It's never recommend to breed a dog on their first heat, as she will not be mature enough physically and emotionally to raise puppies.

Yes she should be starting her period soon. You know that a pet is having their period because you will see a very swollen vagina and sometimes a decrease in appetite. So this could explain what you are seeing. Look at Hina's genital area to see if it is indeed swollen. A pets period lasts anywhere from 2-4 weeks on average. And the decrease in appetite is normal during the first week of a pets menstrual cycle, but should improve gradually. If the blood is not coming from her genital area and is instead coming from her rectum, then its best to have her seen by your vet for further treatment. I hope everything works out well for your pet Hina. Take care.

Most dogs typically go into heat twice a year. The questions to ask yourself are: 1. Has she ever done this before? 2. Does the blood look different? 3. Is she behaving differently? Occasionally, bitches do slow their bleeding and then start up again briefly towards the end, but it is not worth the risk to assume this is the case here. If this is not how her heat cycles normally progress, it is possible that she has [pyometra](https://www.petcoach.co/dog/condition/pyometra/), or an infection of the uterus. Pyometra is common in older, intact female dogs that have recently had a heat cycle. It is a very serious condition that typically requires surgical intervention. Please bring her to your veterinarian or the nearest veterinary ER to be on the safe side. She needs to be seen ASAP, especially if she is lethargic, [feverish](https://www.petcoach.co/article/6-common-signs-your-pet-has-a-fever) or has a tender abdomen.

No, this is not normal. LuLu may have a uterine infection which can be life threatening. You need to have her examined by a veterinarian as soon as possible. Drinking and urinating more than usual and appearing quieter than usual would also be signs consistent with an infection. The veterinarian will give her a thorough exam, blood tests and possibly take an x-ray to visualize her uterus. Should LuLu get lethargic you need to take her to an emergency clinic.
