My Zoey gets so angry when I find her bones. I give her a busy bone a week and, instead of eating it, she'll go hide it under a bed sheet, behind a pillow or in my backpack. So I always end up finding it and I place it typically on the floor close to where I pulled it out. Once Zoey sees it she throws a fit. She looks at me with the bone in her mouth like 'why are you getting my stuff?' then she'll go and spend 30 minutes to an hour finding another place to hide it (typically under the other pillow) and watch me. She has literally run back inside the house when she senses that I'm too close to her bone.
