Kona does the same thing...He'll be in the backyard burrying bones all over the place.
Another thing he will bury are little toy treasures he finds from my kids. I find it so funny and cute. If he's burrying a bone or some treasure, and if he spots us, he'll stop, walk away as though he wasn't up to anything, then once we're out of sight (we'll be hiding), he'll go right back to finishing what he was doing. CUTE!!!
I would love to know what is going on in his mind too. We've never taken a treat back when he's been given it, so I'm not sure why he acts like we're going to steal his treat back. LOL
