How Long Does a Chihuahua stay in heat?

How Long Does a Chihuahua stay in heat?

A chihuahua’s heat cycle can last between 21 and 31 days. Some chihuahuas experience shorter or longer cycles, depending on the chihuahua’s breed and if she has been spayed or not.

If a chihuahua has not been spayed, her estrus will typically last for about 21 to 29 days and around the 30th day, she is open (not pregnant) to breeding.

If you want your chihuahua to be as healthy as possible, we suggest that you have her spayed before her first heat at around 5-6 months old. This will ensure that you donot need to go through this process again until she is much older.

A Chihuahua’s heat cycle can vary from dog to dog and breed to breed. Some dogs may experience their first heat cycle as early as six months, while other female dogs may not reach this stage until they are 18 months old. 

It is important to know when your chihuahua goes into his or her first heat cycle because this will determine how long the whole process lasts.  

In general, however, it is safe to assume that a Chihuahua’s estrus cycle will last about 21-24 days from when she begins her period of proestrus. During this time, there are some physical signs that you should be aware of. 

The most noticeable symptom is vaginal bleeding, which is caused when the cervix dilates to allow sperm in. 

This is called “proestrus”, and is considered to last from anywhere between nine days to three weeks. 

Some female dogs will also have a funny odor that they carry around with them during this time, so if you notice your dog is acting different for no apparent reason, it might be because she has gone into heat.  

During the second stage of the estrus cycle – called “estrus” or being in “heat” – your Chihuahua will begin ovulating. 

This stage can last up 21 days as well, and continues until your pet goes into anestrus, which is the final stage of the estrous cycle. 

This last phase can also span from anywhere between nine months up to about a year-long, and during this time your female Chihuahua will not be receptive to your male dog’s advances.  

If you notice that your female chihuahua’s heat cycle lasts longer than normal, gets shorter as it goes on, or she bleeds for more than 21 days at a time without going into estrus or anestrus – consult with your vet right away to get her checked out. 

It may be possible that there is something wrong with either her reproductive system or her hormones, so it’s best not to wait until she has been in heat for more than a month.

The heat cycle occurs when the chihuahua’s body releases two types of hormones called an estrogen hormone and a progesterone hormone. When these are released, it triggers the chihuahua to have proestrus for about three weeks which is when she will stay in heat.

Facts about Chihuahua proestrus:

– chihuahuas that are not spayed can easily become pregnant during proestrus. This is because this phase attracts male dogs with its pheromones which are strong enough to make even men fall in love!

The males pick up on the chihuahua’s scent through her urine or blood if they fight or one mates with another female. Sometimes, even females in heat will drive males chihuahuas wild, even if they are not pregnant or going through proestrus.

  • – chihuahuas will lose a large amount of blood during this time which is why it is important to keep them as calm as possible and give them lots of rest.
  • – chihuahuas will also be more prone to infections and diseases at this time due to their increased stress levels from various factors such as the breeding process, annoyance from other chihuahuas, etc.
  • – If you want your chihuahua to experience an easier heat cycle without getting too stressed out, we recommend that you have her spayed before her first heat at around 5-6 months old. This way, she won’t go through estrus again until she is much older.

The chihuahua’s heat cycle (estrus) will last for about three weeks which is when she will be open to males. Now that you know chihuahuas stay in heat, the next step is learning how to tell if your chihuahua is in heat or not.

If you notice some of these symptoms, then it’s likely that your chihuahua is going through proestrus or estrus:

  • – swelling of the vulva
  • – discharge from the vagina – bleeding from the vagina – restlessness and pacing around while trying to escape outside through any possible entrance (doorways, windows, cracks in walls)
  • – her desire for frequent attention and affection from owners
  • – chihuahuas will lose a large amount of blood during this time which is why it is important to keep them as calm as possible and give them lots of rest.

If your chihuahua has gotten pregnant, then it’s important that you provide her with plenty of nutritious food to ensure that she recovers well.

You should also take good care of yourself by getting enough sleep, exercising regularly (to decrease stress), drinking lots of water (6-8 glasses per day) and see your doctor if you are feeling run down or stressed out.
