The keys to quick success are a training crate, a watchful owner and a consistent plan of action. You don't put family into a cage. From now on, think of the crate as the dog's very own den. Canine species are den animals. If a dog has a crate in it's very own den-like spot, it derives a feeling of security from being in its crate.
Some animals use cages, such as hamsters, gerbils, and mice.
These pets live their entire lives in cages for their own protection. Your dog is not going to live in it's crate. It will rest in it, sleep in it, travel in it, possibly even eat in it. The crate's first use is as the dog's bed, but it is also an excellent natural training tool. You wouldn't try to raise a baby without a crib.
