Why is my 8-year-old Chihuahua having her first long bleeding cycle?

No, stress should not alter her normal heat cycle. Older non neutered females are very prone to womb infections which can be severe and life threatening. Any changes in timing, volume or color is a concern and full health check would be recommended as soon as possible, urgently if any fever, vomiting or weakness is present

I recommend to have Izzy examined by her veterinarian today. Dogs who are in heat will have a bloody discharge that is usually very light colored. Infections in the uterus can be severe and even fatal if not treated quickly so it’s best to have her checked for this today. Cancer and vaginitis are also possible. Best of luck and please feel free to post any additional questions.

Has she been in heat recently? At her age with not being spayed I would worry about thisbdisxharge being from the uterus and her having an uterine infection. This can be an emergency that typically requires surgery. Often times they are weak, drinking more water, vomiting and not eating. Other options include a bladder infection which will need antibiotics. Your vet can distguish between the two and see what is needed

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.

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.

Hi, it is probably better to have her checked over. Sometimes it can be secondary to hormonal fluctuations and changes in the uterus over the course of the years. However, best to be on the safer side and have a check up to make sure that she is not becoming anaemic and that the bleeding is not secondary to something else more concerning .

Hi, yes there is treatment for it. It does sound like Kooky could have an infection of her uterus. She will need some treatment for her which could be medical or surgical. I would recommend to have her checked over as soon as possible to discuss this with your vet. Hope this helps !
