A Trained Pup is a Good Pup..
Benefits of Crate Training
There are a lot of good reasons for crate training. For one, it is an essential part of housebreaking. Puppies will not usually soil their bed. Therefore, if the crate is set up as a resting space, the puppy will wait until he leaves the crate to do his business. This will put you in control of where and when your puppy relieves himself.
You will find that the crate is also useful for sequestering the dog when you have company over, car travel, and for making sure that the puppy is safe at night -- i.e., not eating thing left within reach, tearing at furniture, or soiling on the floors. Think of the crate as a little cave in which your puppy can feel safe and secure, and he will respond positively to it.
