We have a dog that is about 8 months old. When we first put her to bed, she would wake up in the middle of the night and bark. We learned that we needed to just let her bark and she would learn that nothing was going to happen. That worked and for about 5 months she slept for ~10:00-5:30. Now, about 5 months later, she has started barking again and also become very agressive to our other dog. We are concerned about both issues, but for right now we want to get this waking up in the middle of the night and barking, whinning, etc fixed. (Currently we have given our other dog to my wifes mother until we can get some training done for our 8 month old puppy.)
During the months she was sleeping through the night she got a little exercise and I do realize that she should always get more, but she was sleeping without much. Now she is getting a more exercise but not sleeping. My wife is pregnant and needs her sleep.
Her crate is covered. She has two toys in her crate with lots of blankets.
Does anyone have any suggestions? My only thought is that my wife is a teacher and has gone back to work. Before she was home during the day. Could this be the reason? If so, any suggestions on how to get the dog used to be home all day?
