ok 1st off iam not stupid i know what the signs r when she is going into labor, its just ive just have a 7 month old & a 5 yr old so iam kinda back & forth with my kids and trying to watch my female at the same time lol.. well anways me & my husband bread her with our male and anyways ofcourse she is pregnant & HUGE AS EVER NOW..the bad thing is we totally forgot 2 wright down when they mated. she has been shitting alot and his kinda runny, i know that sounds gross and she is pissin alot outside, her boobs have dropped and her boobs r full of milk, tha milk is just coming out if u touch em.she cant hardly get up on the couch or anything, so my question is during the last couple of days before she does have them, is there any signs that i need to look for to know she is gonna have them in the next few days? she got preg around the 20th-28th of august! iam just worried about her , she's my baby and she is just soo huge. she wasnt like this with her first litter last year

She's your 'baby'.but you didn't bother to get her any routine prenatal care during her pregnancy? Lack of that is the biggest cause of whelping complications that could have been easily prevented. Your DVM would have gone over all of your questions with you during one of those visits, so you wouldn't have to be asking here. We normally like to see them at least once during the final week of pregnancy..but if she's already going into labor, you've waited too late for that.
