Have things gotten any better? Just curios,,,,,,I was reading your post and felt really sorry for you.
Currently I have turned my dd's bedroom – thankfully she's away at college -- into a kennel. There is a 6 x 4' ex-pen w/top taking up the entire floor space of her room. Both Jazzy's and Keoki's crates are in there. At night he sleeps okay in that ONLY as long as BOTH crates remain open into the pen.
If I close either crate, he flips out.
During the day when we have to go out, as yesterday and today, I have to remove all "real" bedding and leave just paper toweling. Yesterday I made the mistake of leaving a small piece of carpet UNDER Jazzy's crate, and when we got home it had been pulled out and torn to shreds.
It is obvious that he still wigs out, even in the large pen w/Jazz as today I noticed that the front of his crate {above the door, which was open} has been all chewed up, even though he was not shut in.
Still working with the behaviorist; she and the vet are thinking long-term meds may be in order. That is still being discussed. He's going to hurt himself one day if we don't get a handle on this...and eventually dd is going to be home from college; then what?
We can't travel with him like this either.
