Maybe I should start with a bit of back ground... We have an almost 3 year old Westy. His name's Ernie and we love him dearly. We also have a cat called Sox. Ernie's domain is the down stairs of the house. Sox has the upstairs. Ernie and Sox don't socialize, never have in the 3 years they've lived together. At night, Ernie is put to bed in the front room. Curtains closed. Door closed. Lights off. It has always been the way and has always worked. Ernie has his last food at 6:00/6:30 daily and is put to bed at 10:00. Before bed, he has a 15 minute trip out in the garden to go to the toilet. The problem, as of late Ern has started waking up at 3:00, 4:00, 5:00. It's not always been a problem, he always used to sleep through the night. In fact of a morning sometimes we found that we sometimes woke him up with our normal routine. He's been doing this now for the whole of April. It may not seem like a big problem, you may think "put him back to bed, all will be fine" the problem is, he doesn't go back to bed. He howls the minute we try to. Its almost as if he is afraid of the dark. There doesn't seem to be a reason. On the odd occasion he does need to go to the toilet. Other than that, its almost like he feels the need to go on patrol around the house. He did the same last year, eventually it stopped after a week, but it has gone on longer this time. The additional problem is because we live in quite a close community, we don't want to let him continue howling and barking, as it wakes, not only everybody in the house, but all of the neighbors. This adds the additional question of are we giving him a new habit by going to stop him howling and comforting him so he doesn't continue. I just wondered if anybody else has had a similar problem, and if they found any resolutions. Me and my partner are struggling for a reason behind this behavior and would greatly appreciate any kind of help or advice that anybody may have!
