This is very different from demand barking. Some dogs, particularly many of those with separation anxiety (SA), can’t tolerate the close confinement of a crate. They experience a full-blown panic attack, and frantically try to escape from their prison.
A panicked dog’s efforts to escape from his mental and emotional anguish may include hysterical, non-stop barking and howling – for hours and hours without pause; frantic attempts to bite and claw his way out – often breaking teeth and ripping out nails in the process; and stress-induced urination and defecation – which he proceeds to paint all over the walls of his crate as he thrashes around.
Solution to panic: Don’t crate!
You cannot subject a panicked dog to these conditions. You must address the SA problem through behavior modification, and may someday be able to use a crate with your dog, if you are successful in modifying the SA. In the meantime, look for doggie daycare-type management solutions.
