I have a two year old boxer named Emmie. She chews things out of spite. When my husband comes home from work, he must spend some time with her before he takes a shower, or else. One time she pulled the insulation out of the walls in the basement. Another time she chewed the cord to his work fax machine. But the best was when she chewed the digital tv remote form the cable company. She actually separated the top piece from the bottom piece and removed the green board from inside! My husband called the cable company and they said it would cost us a fee to replace it, but when they saw the remains of the remote, the girl could hardley speak she was laughing so hard, and we got the replacement remote for free.
