How do I get my dog to stop destorying things when I leave? I recently took in a 11 month old boxer mix who is very playful. When I'm home we play and lounge together and he is relatively calm, but when he is home alone he runs amuck around the house destroying items and ripping up anything he could find. He may have a past of some abuse and informed by a friend who works with a cat adoption program that he could have anxiety issues when left alone. He recommended "crate training" and leaving my dog in a crate while I'm not home. Is there any other way I could correct this behavior? Any help or info would be greatly appreciated.
