My dog had a split heat. Will her cycle be normal or unpredictable?

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.

It is highly unlikely this is a true heat unless the first one was very short (3-5days; often referred to as a split heat). I would be concerned she may have an infection which the male is confused by. A full vet check and possibly a sample of the fluid being passed to be examined under a microscope would be recommended in order to determine exactly what is going on and to treat appropriately

Yes, mating does not affect the length of the heat cycle, so she may continue bleeding even after being bred. Dogs can mate several times within a heat cycle, and puppies can even be born with different dads within the same litter.

Thank you for submitting your question regarding Akira. The heat cycle in a dog will typically last 18-21 days. Dogs usually become receptive to a male dog during the middle of the cycle, but every dog will be different. It is possible for her to have become pregnant if she was left alone with an intact male dog. I would supervise her carefully for the remainder of her cycle. I hope this information helps!

Hello. It is very normal for young dogs to have split & prolonged heat cycles the first few times. They usually regulate to a more normal rhythm later on. As long as every test turned up nothing abnormal, you can definitely wait a bit. Thanks for using Petco Pet Education Center, formerly Petcoach.

This doesn't sound like a miscarriage. The blot clot is probably just normal from the heat cycle. I would not be worried about it unless bleeding persists. As a side note, a puppy at 9 months old is probably fertile; rarely are they "blank". They become sexually mature and able to breed a female at about 6-7 months of age. I suspect that she will get pregnant. If you don't want this mating I suggest you speak to your vet about a mis-mating injection.

A dog's heat cycle lasts for around three weeks, so if she started on February 26, it should be ending soon. It's normal that she is spotting occasionally, and you know when she's out of heat when the discharge stops. Now if the bleeding continues for longer than three weeks or Sophie develops other signs such as anorexia, thick pus filled discharge, vomiting, increased bleeding, and/or lethargy, this is not normal and she will need to see a vet immediately. Good luck, I hope this helps!
