I mentioned that Jilli came to visit us about a month ago. Jilli is Chris' Uncle Rick's dog. (Follow that? If not, think of it this way... Chris and Jilli are cousins.) Jilli has also done something that I have only dreamed of. She has become a star.
Recently, she did an Internet game for a large veterenary medicine company. Here's the link. You can type in standard doggie commands and she will do them.
After you have tried a few basics, I recommend trying "Jump," "Dance," and "Achoo!"
