What type of crate or confinement area works best?
A metal, collapsible crate with a tray floor works well, as long as the crate is large enough for the dog to stand, turn, and stretch out. Some dogs feel more secure if a blanket is draped over the crate. A plastic traveling crate or a homemade crate can also be used. Playpens or barricades may also be successful as long as they are indestructible and escape proof.
