The other night my son got up sick and crying about 4:00, and in the process of me caring for him, the dogs got woke up.
Mazie (our barker!

) yapped and yapped for awhile. I warned my husband to "ignore", but he kept getting up and messing with her, and then finally let her come get in bed with us.
Guess what?!

After NO problems sleeping in her crate, all this time....the next night she woke us up barking at her "new" getting-out time---4:00!
THIS time hubby ignored, and hopefully she's back on her PROPER schedule, now!
