Most consider the use of a crate as unfair confinement, or even harmful to the dog. For many typical pet owners, this is their first reaction. Being human beings, who value freedom, they envision crates a inhumane. Considering your pet as an extension of your human family, you do not wish to inflict unjust punishment upon your 4 legged child. OK, so this isn't a direct quote, but try to see a crate from another point of view.
Dogs have a den instinct.
The dog crate helps to satisfy this instinct. You see it as closed in - he sees it a security. You may object to being controlled - he only wants to please you and do whatever you wish. Correctly and humanely used, a dog crate can have many advantages for both you and your pet. You want your pet to be part of your family and to show appropriate behavior.
