Have you considered doggy day care? It isn't something I ever tried, but Tess had serious issues with SA and the crate. She would literally bounce so hard and persistently, that I would come home and not be able to open the back door because she bounce the crate clear across the kitchen and wedge it in the laundry behind the door. Not only that, but she managed to collapse it just far enough to get out of it, and then proceed to tear up the house. She even managed to cruise across the kitchen, pull the phone and answering machine off the counter, and squeeze it under the bottom bar on the crate. I even tried putting our 40lb dog food can on top of the crate to keep it in place - what a joke! This was just a puppy mind you, not even 30lbs.
Long story shorter... I ditched the crate and started locking her in the laundry room, which is basically an overglorified crate (4'x6'), and resigned myself to accepting a lovely hole in the back of the door and no knobs on the washer or dryer (she jumped up there, ate the knobs, and peed - every day!). I still use a pair of pliers to turn the washer on - and Tess is 10 - I just refuse to spend $60 on that one timing knob. She grew out of the destructive behavior, partly because I got Tenaia so she would have a playmate, but she also wasn't getting any reaction from me anymore - good or bad - when I got home. I guess it is kind of like kids (I have 2 of those as well) - they lose interest if no one gives attention to the bad behavior.
Now my two are allowed run of the living area of the house when I am not home. They seem to know exactly what they are 'allowed' to chew up when they are protesting being left at home. Sometimes I come home to a paperback novel completely shredded in the living room, and a couple of times I arrived to find several DVD's in the middle of the floor - boxes destroyed, but not a single mark on the actual DVD. Since I don't know which one did it, though I suspect they both share in the fun, they both get a scolding, but I have learned to roll with it and not let it piss me off. After all, they could be shredding the furniture, but they don't. A couple of days ago, it was my Victoria's Secret catalog - they must think they need some pretty panties! It really doesn't happen very often, so why get upset?
I leave the TV on for them during the day as well (sometimes the radio). It seems to have cut down the outburst frequency considerably. Perhaps you could try that - maybe it will help.
Good luck and hang in there. It will get better.
Jen, Tess and Tenaia
