Hello, We have a 31 week old dog. When we first got him home he cried at night for about a week in his crate but quickly grew to love his crate. Since he's been 10 weeks old, he hasn't cried at night until the past week. I'm not sure what has set him off, nothing has changed at home apart from his general obedience training and off lead/recall training has progressively gotten tougher but he well praised and is rewarded with treats. During the day, I quite often find him having a snooze or a play in his crate. I work from home full time so he's not left alone while my partner's work is office based so he is out 9-6 during the week. We've also noticed that he gets rather upset if one of us leaves the room and takes him a while to settle. Could it be that he's bonded with us and misses us more than when he was younger? Should we start at the basics with his night time routine and leave the radio on, smelly t shirt, hot water bottle, cover his crate etc? We did notice that last night most the most unusual for him, when I tried to put him in his crate, he looked absolutely terrified. I have no idea why he would feel this way, we have worked really hard to make him feel his crate a happy, positive place. I don't think he's been spooked by something at night, he has a different bark for that. We also have those motion sensor lights in the back garden and we haven't noticed anything unusual at night. Also, at what point do you think a behaviourist should be involved? Any advice would be much appreciated.
