I was considering a crate at first for my husky pup, but decided I didn't really need it. I can see how the dog can find it comfortable IF it's allowed to leave/enter it at will, but once you lock them in it seems a little "put the dog in the cupboard" to me? Instead he's learnt that his bed is on the floor at the end of my bed, and will happily wander to it himself later in the evening. I can't really think of a reason I'd actually need to crate him. Maybe to take him on an aircraft or something but I don't see that as likely. It annoys me seeing people asking questions like "how long can I leave my dog in it's crate". If you don't have time for a dog then don't get a dog ..
