There are many signs indicating that whelping time is near (within 12-24 hours), such as:
- Drop in temperature-we typically have the owners take the rectal temperature of the bitch every 12 hours starting 7 days prior to anticipated due date. Usually 8-24 hours prior to delivery, the temperature will have a significant drop of 2 degrees to about 98.6° F.
- Loose stools
- Decrease in appetite
- Increased mucoid vaginal discharge
- Milk in mammary glands
