Why did my pregnant dog's temperature drop then rise before labor?

Updated On September 23rd, 2025

Pet's info: Dog | Bluetick Coonhound | Female | unspayed | 10 months and 24 days old | 40 lbs

I have a bluetick coonhound who is 59 days pregnant. I habe been checking her temp all week and this morning around 8:30 am it was 97.4 i took it again tonight about 9:00 and it was 100.2. Her vulva is really swollen and im not sure if i should worry where it went back up.

Usually, the body temperature does go back up into the normal range before labor actually begins - so this sounds normal :) I would expect that she will probably begin having puppies within the next 24 hours, based on what you're describing here.
