When my late dog Zelda was just a puppy, she had a terrible time teething. Her favorite thing was socks and pantyhose. She was so quick and wily that she could almost always take them right from us and run away until she was bored. We got tired of it but I couldn't think of way to deter her. So I grabbed a sock from my gym locker and made it STINK in every-way possible I could think of. I put it under the kitchen table so she'd have to find it on her own. And I watched her as she went for it. She picked it up, and then spat it out. Then she picked it back up... I gave up after that. She eventually phased out of it.
