Being prepared and knowing when your chihuahua is about to give birth can make the difference between a safe delivery and one that ends in tragedy. Since they are so small, chihuahuas often require caesarean sections; however, if you are not aware of the signs of labour, your chihuahua and her puppies can become seriously injured or worse. Keep a close eye on your dog at all times about a week before she is due to watch for clues she is going into labour.
Take your dog's temperature rectally. Place lubricant on the end of the thermometer, insert it into her rectum and leave it in for about three minutes. A dog's normal temperature is between 38.0 and 39.1 degrees Celsius. If your chihuahua's temperature is lower than 37.8 degrees Celsius, she will likely give birth within 24 hours, states the chihuahua information website PetChiDog.com.
Listen and look for abnormal behaviours. A chihuahua who is entering the first stages of labour will often vomit, refuse to eat, become restless or cry.
Watch your chihuahua closely and monitor her actions. If your chihuahua is entering the second stage of labour, she will probably go to her whelping box and dig or crouch, according to DogBreedInfo.com. She may start shivering and licking her vulva, as well.
Listen for grunting and look for pushing, as these are signs your chihuahua is in active labour. Watch your chihuahua and look for any signs of abnormalities, such as green discharge before birth, a baby stuck in the vagina or twitching. These are signs of an emergency, and you should take your chihuahua to the vet immediately.
Signs of a pregnant chihuahua include a hard stomach, enlarged nipples, lethargy and excessive cleaning. A pregnant chihuahua's stomach will become large rather quickly, faster than most other dog breeds. If you are still unsure if your chihuahua is in the family way, take her to a veterinarian for an examination. Prepare an area for your chihuahua to give birth. Place blankets in a box or area for your chihuahua to rest and eventually have her babies.
If your chihuahua has given birth to one pup and has been pushing for more than two hours without the other puppies coming out, take her to a veterinarian immediately. In addition, if it has been more than 24 hours since her temperature drop and she hasn't gone into labour or if she seems like she is in a large amount of pain, take her to the vet.
