My poor little nut of a Yorkie is stuck outside the dog door again. There is nothing stopping him from coming into the house, except for what is going on between his ears. This happens every so often. He will stand in front of the dog door, and he then arf's about every 30 seconds. This will go on until one of the other dogs changes something, or he makes me crazy enough to call him in, or squeak one of his toys. If I use squeaky toy method, he can get in house faster than greased lighting. It's a darn good thing that I love the little nut.
