Treats don't last long enough in our house to worry about "burying" them.
Eat 'em or loose 'em seems to be the motto of our two. lol
However, Gracie use to do this when she was teething. She'd walk around the house with her ducky in her mouth emitting the most pitiful of whines. It just broke my heart.
Now she walks around with ducky growling and yammering to it, carrying on such long complex conversations with it.
She is such a hoot!!
