I found this and thought it was cute, though it needs to be called "Yorkie Property Laws"
Dog Property Laws
1. If I like it, it's mine.
2. If it's in my mouth, it's mine.
3. If I can take it from you, it's mine.
4. If I had it a little while ago, it's mine.
5. If it's mine, it must never appear to be yours in any way.
6. If I'm chewing something up, all the pieces are mine.
7. If it just looks like mine, it's mine.
8. If I saw it first, it's mine.
9. If you are playing with something and you put it down, it automatically becomes mine.
10. If it's broken, it's yours.
