I just saw my aunt at a party today. She has four dogs and one of them has severe separation anxiety. My aunt got her at a shelter last year and she'd obviously been abused. My aunts says she literally has to take her everywhere. She'll eat through walls, thick gauged chain link fences, wood fences, etc... My aunt is afraid she'll hurt herself. I guess this poor dog has the most severe case my aunt has ever seen.

The only suggestion that I could think of is crating her, but my aunt said that the dog will make herself totally sick and hurt her own self even with that.

Any other suggestions?
