My female is at day 61 of her pregnancy. The past couple days her temp has been between 99.2-99.9. This morning it dropped to 98.6 (checked it twice) but now it is back up to 99.2. In the past she has always dropped to 98.4 and has went into labor within 24 hours. My question is did I get a misreading this morning or is she close. Also she usually delivers day 63 or after. She is a golden retriever is this helps and it is her 4th and last litter. She is also 5 1/2 years old.
