I have an 8 mo. old gsd who chews up or through EVERYTHING. I've tried different Kong toys, treat dispenser toys, deer antlers, balls, etc, and she will play with them for a little bit but all she wants to do is rip things apart. I can't find a toy to satisfy her. Even with toys in her crate, she'll just ignore them and rip up her bedding (only if I'm not home of course). She's happier with a stick outside than anything. Anyone have any suggestions?
