I got a way to determine if it's the right dog. Stand back and say, "Here, Snowball! Come here, Snowball! You good little poochie-woochie, how about a rub on the wittle belly for such a good doggie..."
Hey, if the dog keeps walking, try "Muffin" or "Scooter". Either way, you'll never know until you try...
Did anyone ever find out why George W Bush took away the poor child's dog?
