Risks for Pregnant Chihuahuas

Newborn Chis are tiny, but not proportionately so in comparison to their mother. In addition to being "big" puppies compared to their mothers, Chihuahua pups have large, round heads that are difficult for the mothers to push through the birth canal. Because these issues can cause problems for mother Chihuahuas, cesarean sections are frequently necessary; some Chihuahua parents even opt for planned C-sections.

The average size of a Chihuahua litter is three puppies, but they've been known to give birth to up to 10. The size of the litter can cause problems for mother Chihuahuas; fewer pups isn't always a better scenario. With a large litter, the developing puppies might need more room than the mother has to give. That can lead to premature delivery or even a burst uterus. If your Chihuahua is only carrying one or two puppies, though, they can grow uncommonly large, making it even more difficult for the mother to give birth naturally.

Hypoglycemia is a problem common to Chihuahuas in general but, when a female is pregnant, it can become an issue for mother and puppies alike. Your mother-to-be needs sufficient nutrition to ensure that her blood sugar doesn't drop to dangerous levels that can cause seizures or even death. A mother Chi who has hypoglycemia can have hypoglycemic puppies, as well.

Sometimes mother Chihuahuas develop a condition called eclampsia, also known as milk fever. It's caused by low blood calcium and can be brought on by poor nutrition during pregnancy. A large litter for a small dog can be an issue, too, as numerous puppies will demand more nutrition from their mama. This condition is usually one that occurs within a month after puppies are born, but also has been known to show up in the last few weeks of pregnancy.

You should consult an experienced veterinarian regarding the health and treatment of your pregnant pooch; any odd behavior or symptoms should be brought to the attention of your vet. Stumbling, glassy eyes, listlessness and sometimes seizures are signs of low blood sugar. Irritability, panting, muscle spasms and fever can indicate that your Chihuahua has developed eclampsia. Additionally, if you take your pregnant Chi in for regular checkups during gestation, your vet can keep an eye on developing issues as well as monitor the growth of the puppies to help determine if a planned C-section will be necessary.
