If you have a Chihuahua that made it out of the house when she was in heat and met up with a male dog, you might have the jitters about a possible pregnancy. In which case, you’ll want to know how long is a Chihuahua pregnant for?
The usual length of your Chihuahua’s pregnancy is between 58 – 68 days. This article will discuss the Chihuahua pregnancy stages and the essential facts you need to know.
You might have heard that pregnancy can be a difficult time for female Chihuahuas. Most Chihuahua births are by C-section, which in itself isn’t something you need to worry over. It’s a standard procedure these days.
Essential Facts About Chihuahua Pregnancy
A female Chihuahua can be pregnant during her first heat cycle. Toy dog breeds can conceive when they are very young, between four to seven months old.
Most reputable breeders will not breed a Chihuahua as young as this, though. They would wait for at least the second heat cycle, some even up to the third.
Even if a tie isn’t successful, the female can still be pregnant. Owners not wanting a pregnant female Chihuahua separate the two dogs before a tie; it’s still no guarantee the female will not be pregnant.
A Chihuahua can become pregnant by more than one dog. Female dogs can produce more than one ova in a heat cycle, and they remain in the womb for a few days.
A male can fertilize one egg, and a day or two later, another male fertilizes a second egg. The common term for this is a multi-sired litter.
Chihuahuas have been made pregnant by large dogs. One of the reasons why Chihuahua owners freak out when there is an unplanned pregnancy-it’s challenging to know who the father is. Of course, it’s hazardous for a Chihuahua female to become pregnant by a large dog.
The female herself might try to escape to look for a male. So take great care when she’s on heat.
Males will also come calling. A female Chihuahua on heat will deposit minute amounts of blood in urine, which a male dog can smell. Before you let your dog out or take her for a walk, make sure no male is lurking around.
There are not many puppies in a Chihuahua litter. The average number of puppies in a Chihuahua litter is three. In the first litter, there may only ever be one or two puppies.
There have been cases where a female Chihuahua has given birth to many more; a Chihuahua mommy gave birth to eleven puppies in one litter. She’s now in the Guinness Book of World Records.

Chihuahua Pregnancy Stages
Chihuahuas are pregnant for three trimesters, each one around 21 days. And there are four stages of pregnancy.
1. Proestrus: this is the stage where we acknowledge the dog is in heat. This stage will last for around nine days. But sometimes, it can be as longs as 27 days. During this time is when males begin to take an interest. She will not be interested, though. There will be a discharge mixed with some blood.
2. Estrus: now, the female is receptive to a male. This stage is generally nine days but can be from four days to 24 days. During this period, the female is fertile.
3. Diestrus: will last for around two months. The female’s estrogen levels are low, but progesterone will peak within weeks of diestrus beginning.
4. Anestrus: this stage will be for around four months; it can be for longer in some dog breeds. This stage prepares the dog’s uterus for the next pregnancy.
