Ok... I have a few question to ask you.

Do you have a treadmill at home? How often do you take your dog for walk in the morning? Your dog is frustrated and this is why he is destorying your house. You need to excerise him a lot to remove the frustration that holds him inside. Speration Aneixty is a frustrated energy because there is no healthy simulation. Imagine this, how would you like if you never can go outside your house. You have seen people coming in and go, but all you do is stay home and do nothing? But get a lot of love and food from people? There is no "fun" game to do at home. Wouldn't you go insane?

I have a rottwelier mix who had a severe seperation anexity and he was dumped at the humane society by his pervious family. A H.S. worker warned me that he will do anything to get out and be close to you. He broke two windows and managed to get out of his crate by chewing up the bar. He would whine alll night, but he is a large size dog. He is extremely strong enough to break or damage anything in his way. He got his face scarred because of that. The pervious owner did a wonderful job teach him to have a good manner like he doesn't get on the couch, or whatever, but they did not know how to handle his seperation anexity well.

I went to humane society once in a while to visit a friend who works there. I was not looking for a dog, but I decided to give him a chance. He changed a lot first two weeks in my home. This might sounds toooo simple, but true and you can try it out yourself.

I took Cody on a long walk for two hours on the first day. On the next day, I got up early in the morning to take him for his long walk before I put him in the crate. After I come home I took him another long walk in the afternoon. It helps with his anxeity and he does not care anymore if I left for a few hours.

Sometimes I don't have the time to get up early, I would put him on a treadmill for an hour or so. Now, no one can believe how much he changed in first two weeks just because I overexcerized him. A tired dog is always a good dog. Simple idea! He is always tired and very calm!
