I saw this somewhere and totally loved it...
Here are the top ten 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...
