For the past four nights my dog consistently wakes up between 345-4am. She is a year old, and has slept through the night fully since she was 4 months old. She goes to the bathroom (both) usually around 1045-11 and then into her crate to sleep. First night we took her out and she had a bit of bad poop. Second night we took her out and she just barked at the wind. Third night we ignored it and she finally stopped after about 15 minutes and woke up at her usual time of 9am. Tonight we're ignoring it again. Nothing in her schedule/diet has changed at all. Why is she waking up and barking/whining up a storm.
