Crate training a dog can have several beneficial effects. It provides security and safety for the dog, while preventing damage in your house. It assists in training, and traveling, and can improve your relationship with your dog. When selecting a crate you should pick one with enough room for the dog to stand up and turn around in. It helps to locate the crate in a room with a lot of activity since dogs are social and wants to be included in the day's activities. When introducing a puppy to a crate place some treats or toys in the crate so that the puppy enters voluntarily. The first time you confine the puppy it should be after it has been playing or exercising and is ready for a nap, never use the crate as a form of punishment for your dog, it should be viewed by your dog as a safe place to retreat. Once the puppy has entered the crate, leave the room, but stay near the puppy in order to hear him. He may cry but don't release him until he stops, otherwise you are rewarding negative behavior. If the crying is excessive you may need to correct the behavior, but stay out of site and keep the punishment light.
