With our first, he wasn't keen, so by 6 months he was out of it, and preferred a puppy pen, Chester, well he was so attached to it, even now at 2 years old he will happily be shut in it, even though we took it off him when he was a year old. As for Harley and Benson, Harley could not wait to leave it, and Benson was fine, but we had to revert back to using it as he was later at picking up house training (as he's blind) but before a year was up, they've been out of the crate. If I was you, I'd give your dog a trial with the crate open when your out, and before you leave him for any length of time, just try short trips to see how he goes. if you say he's not a chewer, it's unlikey he will when your out.
