How do you mend a broken dog?

Someone vandalized the work site and tried to break into our home while we were out yesterday...I only found the evidence after I found Jack running through the house. WTF!?! K the elder was supposed to put both of them in their crates before left for Ottawa? Here he was, loose and totally freaked out

Jack destroyed his heavy welded metal crate in an attempt to escape from these 'people' and now he's his manic old self again. He can't be crated right now but I needed to shower- I came back downstairs after 5 minutes of speed shower this afternoon to find him trying eat the bars of his kennel, cracking his teeth and screaming. Nash, poor lad, just sat and watched, confused and worried about his big brother.

We were out for a total of 45 minutes yesterday. That's all it took to destroy his sense of safety. When MC & I got back home, he was loose and had ripped out the sun room baffles from the dog bars (yes, I have installed dog bars after he jettisoned himself through the glass trying to escape on several occasions). In order to stop him from slipping through the dog bars (this is the dog that once escaped through the cat door - all 97 lbs of him - we created heavy 'dog-proof' screen baffles to attach to the bars. Yesterday, he ripped the baffle and the screen out. I think that we got home just in time to stop him from leaping out. Thank God for that- at least he didn't get loose and hurt, hit by a car or shot by one of my neighbours.

I just called my Vet's office and they're so wonderful; when they heard how he was behaving, I could hear the Vet Tech's voice change. They know his story and how far he's come. She sounded as worried as I am. She consulted with our favorite vet, Dr. Malloy who told me to give him 50 mg. of Gravol every 12 hours, for a max. of 2 days until we can get him in to the office to get him something stronger. I'm so anti-chemical but this is extreme... We've done all sorts of behavioral modification but he still slips once in a while. Never like this, though. This is totally off the scale or I wouldn't even consider medicating.

I feel selfish saying this but this is the most important week of my business-life and I need to prepare. Instead, I've got this big dog, drooling and whimpering, trying to fit underneath the couch I'm sitting on. He's already tried to climb under the ottoman, the PC desk, and tried to fit into the lower cupboards in my kitchen. His brain is not working. He's gone. Totally fried. Couldn't these stupid f*#ks bother someone else????

I was Jack's last chance, when I brought him home from the pound. They pretty much told me so - after 2 failed adoptions, he was too much for any other family. I didn't believe that it could be that bad - I was wrong. It was worse. He has been so badly scarred by his early life that he cannot take any changes, noises or even some smells. Motorcycles terrify him. Children terrify him. Life terrifies him. Right now, I terrify him. After years of being his only trustworthy friend, he now feels like I'm out to get him too. I may never be able to leave him alone again... Does anyone out there what to do with this?

I'd better close this before my tears short circuit my laptop...
