A young puppy should have no problem accepting the crate as his place. Crying at first is caused, not by the crate, but by adjusting to an unfamiliar household. Do not reward barking or whining with attention! If you are sure he doesn't need to eliminate, ignore him until he is quiet, then praise him or take him out of the crate. Do not leave meals in the crate or feed your puppy immediately prior to confining him. Most puppies will spill water left in the crate. Do leave a safe chew toy in the crate for your pet. Close your pet in the crate whenever he must be left alone or can't be closely supervised by a responsible person. Never crate your pet longer than you know he can wait to eliminate, and definitely less than 4 hour intervals during the day. If you occasionally must be gone longer than this, place the crate with the door open in an enclosed area such as a bathroom or laundry room. Place newspapers on the floor of the room to facilitate clean-up. Your puppy should soon stop eliminating overnight and then may be crated in his regular place.
