OP here.... Thanks everyone, I was sooooooo pissed when I first saw the videos... especially when they replied that I have no sense of humor...... I'm glad you all agree with me here. Hopefully they get a few peeved messages on their video and it might make them rethink their position..... probably not though.
edit: Ugh, the poster of the videos is adamantly DEFENDING his yorkie's behavior and saying it's clearly a normal trait of yorkies to exhibit this behavior (snapping at people to defend an object/person)!!!!!!!!. Go on and read the comments on the video, it'll be enough to get you to scream! I just wish I could strangle people through the screen sometimes!!!!!
