Lily was due mar 26 (says her breeder) she may have been off a couple days. She just lost her ligs. So if the 26th was right it would put her at 164, so I'm guessing she is probably around 160 days. I keep thinking I should get her looked at, but she acted completely normal, so I waited, and sure enough the ligs are gone. Good luck. Don't let her make you too crazy!
