Crate training has long been accepted by professional trainers and veterinarians as one of the quickest and least stressful ways to mold desirable behaviors in dogs. Although many new dog guardians initially reject the idea of using a crate because they consider it cruel or unfair to the dog, a crate helps satisfy the dog's instinct to be in a den while alleviating many problems dogs and their people experience.
A dog crate is usually a plastic (often called flight kennels or Vari-Kennels) or collapsible metal enclosed pen that is just large enough for a dog to stand up and turn around. The crate is a place for the dog to be when no one is around to supervise him. It is the dog's bed and sanctuary. Its purpose is to provide confinement for reasons of safety, security for the dog, housetraining, prevention of destructive behavior, and/or travel.
Correctly and humanely used, a crate can have many advantages for both you and your dog:
Because dogs are highly social animals, it is important they are indoors much of the time, even when you are not home or are sleeping and can't interact with them. Your dog needs to feel that he is a part of the family, and that feeling of belonging comes from being included in family activities and living in the house even when her family may not be there.
A crate allows you to leave her in the house when you are away, or unable to supervise her. If she were to spend large amounts of time outside, she would very likely start to exhibit problem behaviors such as barking, digging, fence jumping and chewing. These problems can be avoided by keeping her inside and making her an integral part of the family.
