Watching the Temperature

So.. Roxy is due this weekend. We xrayed 8 babies. 7 are all in a row and one is off by himself. Hopefully not to cause us any trouble. I have started to take her temp and I think my thermometer is off. I have now taken it three times this morning and I have gotten 3 different temps. She seems fine, and ate all of her breakfast. Maybe I'll go and buy a new thermometer. Off to the dog show and hopefully not coming home to puppies.
