When Do I Know My Chihuahua In Labor?

When your Chihuahua will be close to her end of gestation, she will show some signs of labor before start of true labor. These signs of labor are

1. Reduced rectal temperature below 100 F
2. Loss of appetite
3. Restlessness and pacing
4. Agitation

After these signs when true labor begin, she will shake due to pain caused by uterine contractions and strain to push puppy outside. This is true labor which means she is going to deliver puppies.
