I think it's interesting how different BCs respond differently to crates, and our varied responses as BC owners to our views of crates.
I, for one, think that personally where I live, there is a greater chance that my BC will (1) dig a hole out of the backyard, (2) chase the schoolkids (we live right next to an elementary school, (3) torment every squirrel/chipmunk/groundhog in the neighborhood... than there would be a chance of the house burning down in flames while he was in the crate.
Therefore, we crate him. (He's 2 years old). Interestingly, he doesn't go stir-crazy in the crate. He thinks of it as his cozy den, a personal space that he can go to lie down and get away from the hustle and bustle of our crazy home (a large German Shepherd and 4 cats). When we are home, we leave the crate door open and find that we've made it so comfortable that all six animals "fight" to occupy the space (toys and pillows and carpeting) that the BC is upset that his crate is being occupied.
WHen we go to work, if the crate door is in the closed position, he'll whine and paw at the door to get in. He thinks it's a special privilege to get to enjoy the den that the other 4 cats and 1 dog do not get!
