Our 10 week old lab had been sleeping from around 11 pm - 7 am. for 2 weeks and then all of a sudden a couple nights ago, she is waking up around 3 am. and whining. I end up taking her out for a pee and then putting her right back into the crate. After a minute or two, she settles back down and goes back to sleep. I'm just wondering if I should be putting her out to pee at 3 am. or just ignoring her and then she would go back to sleep. I just can't figure out why she is starting to wake up when it's been over 2 weeks since she's done this. Any suggestions. I don't want her to pee in her crate if I "make" her stay there.
