Female Chihuahuas can make wonderful, loving family pets. In fact, many people prefer them because they don’t mark their territory like their male counterparts. If you plan on raising a female Chihuahua, though, you’ll need to be aware of their heat cycle. This is a critical time in their life that requires special care and attention; otherwise, you could end up with a litter of unwanted puppies around the home.
Like all dogs, female Chihuahuas must be properly cared for when they go into heat. This is when they are most fertile and will draw the attention of any nearby males. In addition, Chihuahuas in heat will also bleed, which means you’ll have to come up with a solution to prevent it from getting on the floor. Keep reading and we’ll take a closer look at what to expect during a Chihuahua’s heat cycle.

When Will My Chihuahua Have Her First Heat Cycle?
It’s important to note that all Chihuahuas are different, and unfortunately there’s no easy way to tell exactly when your Chihuahua will have her first heat cycle. Some of them will experience it early, while it may take others well over a year. With that said, most female Chihuahuas will have their first heat cycle between the ages of 6 months to one year.
If your Chihuahua still hasn’t gone through her first heat cycle by the age of 18 months, talk to your veterinarian to see if there’s an underlying health problem. A simple checkup by a professional vet can reveal whether your Chihuahua has a defect or if she’s a late bloomer. On rare occasions, female Chihuahuas may not experience their first heat cycle until they are 2 years old. For your Chihuahua’s sake, though, take her to the vet to check for any serious health problems.
Also, you should NEVER allow your Chihuahua to breed during her first heat cycle. This is a sensitive time when her organs and body are adjusting to this natural process. Allowing her to become impregnated places her at greater risk for complications. If you care about the health and well-being of your Chihuahua, wait until her second heat cycle at the very least.
Evaluating The Different Stages of a Chihuahua’s Heat Cycle
Contrary to what some people may believe, there are actually several different stages of a Chihuahua’s heat cycle. While most owners assume there is only one, there are actually a total of 4 different stages, all of which are unique in their own way.
Generally, female Chihuahuas will go into heat (lasting approximately 3 weeks) about once or twice a year.

Here are the stages of a typical female Chihuahua’s heat cycle:
Proestrus – The first stage of a Chihuahua’s heat cycle, Proestrus, may or may not be easy for owners to identify. Some Chihuahuas will exhibit clear, concise symptoms that include bleeding, swollen nipples, excessive licking and a general shift in mood change. Others, however, may exhibit few (if any) symptoms.
The most effective way to determine if a Chihuahua is going through the Proestrus stage is to closely observe and monitor their behavior. Typically, Chihuahuas at this stage of their heat cycle will begin to chase males around in a playful or even somewhat aggravating manner. It’s not uncommon to find your female Chihuahua constantly badgering any nearby males.
Estrus – The second stage, known as Estrus, occurs about one week after the Proestrus stage. During this time, Chihuahuas are fertile and ready to breed. While most Chihuahuas won’t allow the male to mate with her during the Proestrus stage, they will however allow it during the Estrus stage.
Identifying a Chihuahua in heat during the Estrus stage shouldn’t be overly difficult. They will have swollen, bleeding genitals and the desire to couple with nearby male Chihuahuas. Males will also be more attracted to the female due to the scent of her discharge.
Diestrus – As long as the female Chihuahua did not become impregnated, she will enter the Diestrus stage immediately following Estrus. This is essentially a rest period that lasts for 30-90 days when the Chihuahua’s body is given time to recuperate. She will no longer seek the attention of males, and her body parts will gradually begin to go back to their normal size.
If a female Chihuahua was impregnated, she will skip the Diestrus stage and enter the early stages of pregnancy. Pregnant Chihuahuas will continue to exhibit large, puffy nipples and swollen genitals.

Anestrus – The last stage in a Chihuahua’s heat cycle, Anestrus, is a cooling down period when the body and organs are finally getting back to normal. Owners won’t notice any visible signs of a heat cycle when their Chihuahua is going through Anestrus. Chihuahua will have normal-sized genitals, no bleeding or discharge and regular moods.
The Anestrus stage will last somewhere between 2-6 months until they begin the heat cycle over again.
Tips on Dealing With a Chihuahua’s Heat Cycle
The good news is that most Chihuahuas will only be in heat for approximately 3 weeks. The bad news, however, is that you’ll need to give them extra care and attention to ensure everything runs smoothly. Far too many owners brush off the heat cycle as a “natural” occurrence without giving their Chihuahua the care she needs during this special time.
Follow these tips for a better, smoother heat cycle:
- From the time you notice the first sight of your Chihuahua’s heat cycle, keep her separated from any nearby males (unless you want her to get pregnant of course). This means always walking her on a leash and never allowing her to run off.
- Female Chihuahuas can be a bit more cranky during their heat cycle, so use caution when handling them.
- Use a doggie diaper or wrap your Chihuahua’s bottom up in a blanket to prevent her from bleeding everywhere.
- Don’t make the assumption that your Chihuahua is no longer fertile just because she’s no longer bleeding. Depending on her biology, she could still be fertile for weeks after bleeding. The bottom line is that you need to keep her separated from males until you are completely sure she is no longer fertile.
