Yeah, our Ms Daisy demonstrates a similar behavior. If she has a new bone (usually a good one, like a dental chew) she will attempt to bury it under a blanket to save it for later after she is temporarily finished. However, she is NEVER satisfied with where she had hid it, and continually "digs it up" and then reburies it. I have tried to help her out by burying it more thoroughly so it could not be seen, but she still digs it out and carries on this obsessive behavior. Dont worry about it, even a Yorkie will get tired of this behavior after a while
