No, this isn't normal to spot before going into heat. Dogs typically go into heat every six months, but they can go into heat sooner than that. It could be that Jada is going into heat now, or she could have something more wrong with her such as vaginitis or a pyometra (a life threatening infection of the uterus). Because I can't see her in person to say what is going on, I do think a visit with the vet on Monday is best to make sure everything is ok. If you see other signs such as vomiting, anorexia, thick discharge from the vaginal area, a swollen abdomen, increased thirst, and/or lethargy (all signs of a pyometra), take her into vet immediately. Good luck, I hope this helps!

My dog is nearly 8 years old, not spayed, and typically has 2 heat cycles a year 6 months apart. She had one in June, and now she's having another only 3 months later. Is that something to be concerned about?
This is a bit early for Janie to have another heat cycle, and my question would be: Are you sure it's a heat cycle? There could be a possibility that any discharge you are seeing is due to a pyometra. This is an infection of the uterus that is fatal without treatment, and is a medical emergency. To be safe, I think it's best for her to be checked out by a vet now. If she does have a pyometra, spaying her is part of the recommended treatment. Best of luck.

My 5 year old pitbull is "spotting" 2 months after her heat cycle. It has been once a week ish that just a tiny bit of awful smelling blood comes out. What should I do?
I'd have Iszadora seen by a vet immediately. This "spotting" could be due to a pyometra, which is an infection of the uterus that is fatal without treatment. Please take her into a vet now. If she does have a pyometra, she will need to be spayed. Best of luck.

Our Boerboel had puppies 10 weeks ago. She totally weaned them 5 weeks ago. She was spotting 4 days ago, a small amount, and it only lasted for 2 days. I have her scheduled for spaying next week. Can her cycle hesitate and stop, then start up again b
It could be her heat starting up again, but if she is showing no other signs of heat (enlarged vulva, enlarged nipples), the blood could be from something else like a UTI. Let the vet know, but even if she is in heat, the vet can spay her.

This moning I found these red spots on the sheet where Spica sleeps, I honestly don't know where they came from, should I be worried? I tried to find an answer from internet , maybe it could be from fleas but I don't know all I want is the wellbeing
Poor Spica. There is a good chance that she is in heat if she hasn't been spayed. I would look at her vulva to see if it look swollen and if there is a little bloody discharge from there. If not, then I would have your vet take a look at her to see if she is bleeding from anywhere else especially if you see it again on her bed. I hope this helps!

My almost 4 yr old Standard Poodle has been bleeding, though not heavily, for almost a week now. She had a full heavy heart in early April, right after we introduced our male pup into the home, but he was to young to do anything about it lol. In Augu
It could be that Gypsy is in heat, given that her last true one was in April. It would be the right time for her to go into heat again. The puppy may not be interested in her because he hasn't reached sexual maturity yet. It could also be a sign of a pyometra. This is when the uterus becomes infected, and this is life threatening. Leaving a pyometra untreated is fatal, so the best thing to do it take her into a vet right away. The vet can diagnose if she is experiencing a true heat or if she has a pyometra. If she does have a pyometra, spaying her is part of the recommended treatment. Good luck, I hope this helps!

My dog is leaking brownish liquid from her vagina. I don't know what it is or what is causing it.
If your dog isn't [spayed](https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/), this could be a heat cycle. Or it could be a very serious condition known as [pyometra](https://www.petcoach.co/dog/condition/pyometra/), which means infected uterus. Especially if she had her heat cycle a couple of months ago, and if she's lethargic or has a fever you need to take her in to a veterinarian to be examined tonight. If she is spayed, this could be several things. She could have a [urinary tract infection](https://www.petcoach.co/article/5-signs-of-urinary-tract-disease-in-dogs) and you're seeing her leak blood-tinged urine. I hope not, but depending on her age there could be cancer in the urinary tract that's causing bleeding (blood doesn't always look bright red). Very occasionally spayed dogs will continue to bleed if a piece of an ovary was left behind. Get her checked out by your veterinarian as soon as possible to figure out what's going on.

Can a dog have a season two months after the last one?
No, it isn't normal for a dog to go into heat so soon after the last one, and what you may be seeing is a pyometra not a heat. A pyometra is a life threatening infection of the uterus that requires immediately medical attention. These are fatal without treatment. I would take Izzie into a vet immediately.

Why would my dog be going back in heat? It has been more than 21 days. Now she is bleeding again.
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.

Thank you so much for your advice Melanie! I will listen to your advice. Before that, how am I sure that my dog is on period, and how do I know when did she start being in heat? My guess that she is on period is based on my observation, as shown in t
I'm very glad I could help you! Six months is a little early for a standard poodle to go into heat for the first time as they typically go into heat closer to a year, but it can happen. Her vulva looks a little swollen from your picture, which you do see when a dog goes into heat. You don't always see blood spots when a dog is in heat because they can excessively lick that area, thus cleaning up the blood. This dark brown could be dried blood, and it could be coming from another source such as her bladder. It might be she could have a UTI or bladder stones. Without seeing her person, I can't diagnose if she is in heat or not, but I'd make an appointment with her vet for this week sometime. The vet can diagnose if she is in heat, and you can discuss when would be a good time to spay her. I hope this helps!

My dog has a fever. She's shaking and won't drink any water. She's experiencing spotting bleeding but it's not a lot and she just got off her period
If she is acting sick after her heatcycle I would recommend taking her to a veterinarian as soon as possible. Dogs can get an infection in there uterus called a pyometra. It occurs often after they just finished a heat cycle. This is fatal unless she has divert to remove the infection. It is also possible she has a uti , prolonged heat, toxin exposure or auto immune disease. I would still recommend taking her in for a good check up tomorrow.
