What should I do about a dog that hurts himself while in the crate?

Hey Ed,

I was looking at your separation anxiety page, and, forgive me if I missed it, but I don't think I found an answer to this particular question.

What do you do with a dog that, when kenneled or left alone, is so panicked that he injures himself? I fostered a rescue dog at one point that would bloody himself trying to get out of a crate, and when left loose in a room alone for no more than 30 minutes, he went straight through an interior door and put gouges in the solid exterior door trying to get out. Your response to the first e-mail on the page sounds like you are saying to use a remote collar if the dog is being a "butt head" in the crate. Does this question fall into that category? Have you seen dogs like this before?

Thanks,
Carmelite
