We have a 6 month old french bulldog who is crate trained and sleeps lovely in it during the night. The problem is over the last few days he's been in it for an hour and half while I work and when I've come home he's moved it across the room. He's very upset and anxious. I make sure he has something to play with and it's nice and comfy for him. Any advice on how I can help him to feel less stressed in it during the day. Thank you.
