If he does have to live behind glass and only watch as the life of the house goes on while he's looking on, no wonder he's getting aggressive and OCD barking. He knows he can't get to the rest of his world but can see it, smell it and almost touch it but not quite - which is pretty hard on a sentient animal like a dog and should not ever be allowed. I hope that he's not living there all the time but just when you are working or something. Otherwise, he really needs to be appropriately housetrained and allowed to partake in the home life as just watching and smelling life go by him - a life he can't get to - is really cruel, oppressive, disheartening to the max and is going to create a totally frustrated, very anxious and unhappy dog. I'm thinking you're very unhappy with this as well and suggest for every one's sanity that you stop it immediately and allow this baby to live the life of a beloved family member, which he is. Separation anxiety is the least of the problems you are going to have with this little sweetheart if he has to stay behind glass, no matter how much you visit him. Take the time to learn how to train him right and allow this baby to join the family living life in the home as dogs these days do. You'll find he'll begin to enjoy life, work hard to learn if you make the training regular, gentle, loving and fun and he'll do you proud!
