I completely understand what you're going through. I have a 10 month old Siberian Husky who has major separation anxiety. He starts to whine as soon as I walk out the door. We got a cat which helped a little for a while, now he doesn't really care. Back to whining instantly. Last week I went to take a shower and left him in my bedroom, he whimpered the whole time and I came back with a torn up mattress. We have been working with him now. Unfortunately when he's left alone for too long he destroys things so we got a crate plenty big enough for him. Every day we have been putting him in the crate for a little bit and increasing the time. I have seen an improvement already. At first he cried as soon as he was locked in the crate, now it actually take him a while to begin whining! Of course he is all over us as soon as he is let out but I really think it is helping! (:
