Both my 1yr old chihuahuas are pregnant

Question
Both my girl's are prego one is ahead by maybe 2 wks and both their bellies are getting big, but the one that is behind 2wks is alot bigger, what are symptoms of them going in to labor? and do we need to seperate them now, before they go in to labor? My boyfriend says they will eat eachothers babies in jealously  Please help, Im very nervous for them.

Answer
They won't eat each other's babies, at least not likely. However every dog needs it's own safe, quiet place to whelp with no interference or fear of another dog. Do separate them now.
Signs of going into labor are a temperature drop blow 100 that stays there. Nesting, digging. shredding paper, panting, a discharge, some moms don't eat , are restless and want to hide,. Some are clingy and want to be right with you all the time.
Do take good care of your ladies and make sure you're there to lend a hand when they whelp in case they happen to have any problems
Good luck
