My little girl Sakura and learned our bird Frisco's "someone's here" squawk and now runs to see who is here before they push the doorbell. And if you give her a dog biscuit first you have to break it in half or she won't take it and then she goes to her bed to "bury" it in her blanket. Once it's burial she rubs her nose on her bed and blanket THEN eats the biscuit. She doesn't always do all that but every once and a while.
