Sam's new trick

Outside, underneath the spigot attached to the house, is an old metal wash tub. We usually keep this full of water for the dogs. Sam however has discovered it. I don't know if you want to call it laziness or spoiled, but when it is empty, instead of walking to the barn to her own tank, she is picking up the wash basin and throwing it against the house. And if you aren't out there within a few moments, she will do it again.
