I have a mix dog and she is fairly good. She has been trained outside with a shock collar and I dont really even have to use it on her any more. When I am home she never is destructive and is house broken. She is 2 years old. When I am at work or not home she goes in the crate. I would like to get away from this. Every now and then I will leave her out of the crate and go. When I come back (4-5 hours later), usually magazines are shredded in my dining room or she gets into something, takes it to the dining room and chews it. It is usually paper or even a rug once. Sometimes she will even pee in another area in the house when left alone. When someone is home she will never do this... When I walk in the door she puts her ears and head down knowing she did something wrong. Any thoughts on how to get her to quit doing this and be able to leave her out of the crate?
