It is a rule that you aren't even allowed to come to the table if you aren't wearing green. Happy wasn't here; he was at work. That's another story. :)
Even Blue has a green collar on. :)
PS. Blue is huge. He's a good dog, for the most part... He does have his moments where he just can't help but chase a chicken or jump on a kid or eat an entire car seat, but all in all he's a pretty good "little" puppy.
