Ok.....I found this:
Temperature
Continue to monitor the mothers temperature. The temperature of her body works as a tool to indicate if she has an infection. Your bitch's temperature dropped right before she went into labor and now should rise to 101 to 103. Any temperature reading above 103 is abnormal. This indicates an infection somewhere in her body. Many of the infections can be deadly to your dog, and should be taken seriously.
My vet always told me the same thing - anything 103 and above...call him! I just wanted some reassurance. Maceys's is 102.2. She's drinking lots, eating, peeing and pooping. I think she's ok.
All the placentas were accounted for. My vet is out of town
