I think I can understand where you're coming from. If you are like me you would think they would be more comfortable having more room (aka free roam of the house?). I have 2 dogs that are crated, Peak & Kailey are both crated (Kailey will sometimes urinate on furniture when left alone & Peak will sometimes chew dvds) but "I" would feel better being able to let them have free roam with Kaige. They would be able to socialize & get more exercise even though I know they feel comfortable & like it in their crate.

I "test" my dogs out from time to time to see if they are ready to have free roam of the house (although I don't think I could ever remove the crate all together just leave the door open while I am away). I gradually increase the amount of time left alone with the crate open. It starts off being only 10 minutes or so slowly adding more time. So far my dogs can't go more than about 5ish hours before being "destructive" in one way or another.

Another thing you can do is slowly allowing them more space. Leave the crate open but keep them closed off in only one room by a door or baby gate. Slowly adding more space.

You can also combine the 2, slowly adding more time and space.

Good luck.
