Although many new dog owners initially reject the idea of using a crate because they consider it cruel or unfair to the dog, a crate helps to satisfy the dog's denning instinct while being the answer to many problems faced by dogs and their owners. Plastic is easy to clean, lightweight, and doesn't squeak like the metal crates do when the dog moves inside them. They are generally more comfortable than a wire crate, and make the dog feel more secure.
Crates come in a variety of sizes proportioned to fit any type of dog.
It's just big enough for a dog to stand up, lie down and turn around in. Its purpose is to provide confinement for reasons of safety, housebreaking, prevention of destructive behavior, or travel. The crate is a place for the dog to be when no one is around to supervise. It is the dog's bed and sanctuary. Can housebreak your dog quickly by using the confinement to encourage control, establish a regular routine for outdoor elimination, and prevent accidents at night or when left alone.
