No sign yet. Lots of wriggly puppy movement inside too. She is currently snoring on sofa without a care in world. There will be pics as soon as anything happens. In fact could be pregnant pic if can remember how to upload.
You can narrow down the worry time,take her temperature AM and PM,it will be around 100.5 F ,but will dramaticaly drop down to 98 --99 and stay at that 24 hours before whelping. If there is a temp. drop and nothing happening after 24--36 hours you may have problems brewing. Good Luck!
