I don’t think the Boxers have a problem with chewing, but this owner sure does. I think it is mainly separation anxiety. My Jewel has eaten / destroyed, two complete manicure kits, 2 TV remotes, a small digital travel clock, two paper back books, printer ink cartridge box, various magazines, the electric wires to the deck lights and has spilled a cup of coffee on my computer while looking for other stuff to chew. She never does it when I am in the same room with her and she seems to do a lot of it to get even for being left alone for a short time. And she is not yet 2 years old. I have finally learned to pick things up if I want to keep them. But my older Boxer has never done any thing like that.
