I personally never crated my dogs unless it was for housebreaking. BC are especially prone to destructive behaviors if they don't have their exercise needs met, hen the owners wonder why... Dogs are den animals but even den animals roam during the day and go back to the den to sleep at night. I've had friends crate their dogs while they worked all day and it was easy to see the dogs were bored and not that well behaved. I would wait for a more suitable home. Teens have a lot of stuff going on , they might not want to continue coming home to let the pup out.
