My 9-month-old dog just had her first heat. Is she pregnant already?

If Cali stopped bleeding over a week ago, it's still too early to tell if she is pregnant or not. Her nipples and genital area should go down not long after a heat ends. Even if she was pregnant, it would still be too early for her nipples to enlarge in response to a pregnancy. You can wait at least another three weeks then take her into the vet for a blood test looking for the hormone relaxin. This will be present in her blood if she is pregnant. You can wait six weeks instead and then take her into the vet for x-rays or an ultrasound to see if she is pregnant or not. This will also tell you how many puppies she is carrying. Best of luck.

Not necessarily. A vulva can stay enlarged and swollen for weeks after coming out of heat. Keep a close eye on her. You can have your vet check with an ultrasound at 30 days of pregnancy and with X-rays st 45 days to confirm pregnancy. I hope this helps.

This is definitely possible that she is already back in heat. She could also have an infection so be sure to keep an eye out for any abnormal behavior like not eating, lethargy, or vomiting. If you see any abnormal behavior or just want to be sure, I would have your vet take a look at her to ensure she is healthy. I would not breed her during this heat cycle since she just had a litter. I hope this helps!

If your dog was in heat and was bred with a male then it is possible she is pregnant. If she is having complications or you are unsure, having your vet examine Zoey to confirm the pregnancy and rule out any other health issues is best.

This is a possibility, there is no way to know at the moment, if you start seeing some pregnancy sign in about a month from now (enlarged nipples, weight gain, increase appetite),- take her to the vet in order to do an ultrasound, this will confirm or rule out pregnancy.

It is not unusual for the vulva to remain swollen for a period of time after the "heat" cycle is over. In dogs, there are [4 stages of estrus](https://www.petcoach.co/article/anatomy-and-function-of-the-reproductive-system-in-dogs). The combination of proestrus and estrus, which is often referred to as "heat" by breeders, lasts approximately 21 days. "Heat" is followed by diestrus and anestrus. During proestrus, the vulva swells and has a bloody discharge. During estrus, the vulva softens and becomes pliable in preparation for mating. It can take several weeks following estrus for the vulva to shrink back down in size, but it will never go back to the size it was before the first heat cycle. The same is true of the mammary glands, which enlarge slightly in preparation for [pregnancy](https://www.petcoach.co/dog/condition/pregnancy/).

This would be quite soon for Lila to go into heat again, and I'm wondering if she possibly had contact with an intact male dog during her first heat. Her symptoms could be indicative of a pregnancy, but it could also be due to a false pregnancy. This is when a dog shows signs of being pregnant without actually being pregnant. I would have her seen by a vet tomorrow, who can confirm if she is pregnant or is experiencing a false pregnancy. As for spaying, should she be pregnant, she would be far along in her pregnancy that at this point, spaying may not be an option. If she is having a false pregnancy, yes she can be spayed but keep in mind that if there is an increased blood flow to her uterus, the surgery will cost a little more due to the increased risks. You can speak to your vet to find out the costs involved. I would recommend having her spayed if you can, however, as it will reduce her chance of developing mammary tumors later in life (she will have an 8% chance of developing them), and will eliminate the risk of developing a pyometra, which is a life threatening infection of the uterus. Take her into your vet tomorrow for an exam and a discussion. Good luck, I hope this helps!
