There are a number of reasons to crate train your dog. Most puppies and adult dogs feel more secure in a small, enclosed den-like area, and young puppies are especially eager to find a safe place. A carefully-chosen crate and proper crate training can help your puppy discover that a crate is a safe, happy place to spend the night. A youngster should be introduced slowly to the crate when possible and not left unattended longer than the dog is able to "hold it" for potty training. But crate training, when it's done right, can give both you and your dog a feeling of order and security in a complex world.
