How long is a Chihuahua Pregnant for?
Pregnancy in Chihuahua is comparatively short. It is about 9-11 weeks (63-76 days) in total and each day is really important. Pups develop at a faster pace inside the womb for 2-to-3 months. Knowing how long the gestation period is—is both crucial for the health of the pregnant dog and the puppies.

Chihuahua Pregnancy Symptoms
Most Chihuahuas do not exhibit any sign of being pregnant during the first three weeks of their pregnancy. Some symptoms to look out for during the first month are: increased appetite, lethargy, decreased physical activity, clear vaginal discharge, swollen nipples, and more affectionate disposition.
Moreover, these are the signs that characterize the second month: increased urination, weight gain (20-50 percent), attitudinal changes or variations, larger abdomen (days 45-50), increased appetite, clear, odorless vaginal discharge, movement of puppies in the abdomen (day 50).
These symptoms below are exhibited by Chihuahuas in the last few days of pregnancy: restless attitude, panting, shivering, pacing or digging, a sharp decline in body temperature 12-to-24 hours before labor, and loss of appetite around day 61-62. There will also be trimming of the waist as puppies move into the birth canal.
Chihuahua Pregnancy Stages
In the first month, probably around day 7, the embryos gravitate to the uterine horns and the embryos are lodged in the uterine lining around day 16. By day 22, the fetus starts to take form and by day 28 or 30, a vet should be able to detect fetal heartbeats on an ultrasound. During the second month, the fetus develops at a very fast pace. And by day 32, eyelids begin to form, and toes become visible by day 35.
By day 40, claws develop, and shortly afterward, the skeleton and coat will come out. By day 50, an x-ray will show the number of puppies in the litter and the dog will start scouring for a place to nest by day 53. By the start of the third month, the dog is set to whelp. By day 58, puppy development is almost completed. This means puppies will start to move into a whelping position in the birth canal.
Causes of Chihuahua Enlarged Nipples
Swollen nipples occur as a result of excess milk accumulation. When too much milk is produced in a dog, it piles up in the mammary gland, making the nipples swell. Dirty environments can also be the cause of this enlargement. Another reason for a dog to have swollen nipples is trauma of the teat.
Can an 8-Year-Old Chihuahua Get Pregnant?
It is not safe for 8-year-old Chihuahua to get pregnant. She is too old to be bred. Chances are that she has been spayed in the past. In the bid to make her have puppies, you might be putting her life at risk. You might not even have the experience to breed her as well as puppies. You might not even know how to address certain complications and she can die in the process. Ideally, Chihuahuas are supposed to be bred by expert and experienced breeders.

What is Chihuahua False Pregnancy?
False pregnancy or pseudopregnancy happens when a female dog comes in contact with a male sexually but the fertilization process is not completed. The symptoms of a pseudopregnancy are just like the symptoms of the actual pregnancy. The symptoms of pseudopregnancy include enlarged nipples, swollen breasts, and increased appetite. Dogs having pseudopregnancy can emit serum (which looks like breast milk) from the nipples. But serum is less viscous and it is lighter. To prevent pseudopregnancy, the best thing to do is to have them spayed.
How Many Puppies Do Chihuahuas Usually Have?
Chihuahuas have relatively smaller litter sizes when compared to other breeds. Chihuahuas, on an average, will have about 3 puppies in each litter. Well, 1 to 3 is often the average. It is also possible for Chihuahuas to have some bigger puppies.
In 2011 a Chihuahua dubbed “Coco” produced a litter of 10 puppies in the UK. This is quite impressive. Some Chihuahuas become sexually matured in 6 months, while others cannot have puppies until they are over 1-year-old. Chihuahuas typically have two estrous periods in a year in which they mate. Thus, Chihuahuas can produce two litters a year.
