Some of you may think you know of a completely insane dog. My fiancee's brother has a dog that should be put down. The dog goes bonkers if she's left home alone for too long- (any more than 6-8 hours) Normally, that entails a lot of barking, right? Well if there happens to be thunder, fireworks, or lawn mowing or somthing like that- the dog will attempt to dig through the floor, she'll eat through walls, she'll go through windows, she'll eat doorknobs, and tear up doors, she'll tear off vent covers and get stuck in the ventilation system. Its' not just an occasional thing. They cannot board her anywhere if they go away- no place will take her. She will literally dig herself bloody on the cement pens. Last night we were going to take care of her because they were away and there were going to be fireworks in the evening. We got there right before sunset, and no dog greeted us at the door. After looking around, she had torn an upstairs bedroom door open- pulled the lock out of the doorframe- and eaten through the drywall by a window, pulled all the isulation out of the wall then broke 2 window panes got out onto the roof and jumped off the second story roof. And you think your dog is crazy.
