He'll outlick ANY Yorkie alive, so I'm sure he'll get the Gold in that. Well, outlick them compared to other Yorkies licking their owners... I think his record is like 250 licks per minute... I must have really stinky breath, eh?
But, yeah, the main thing we worry about is his poor joints when he jumps, so luckily he seems fine and that isn't a problem right now. I just hated to see him limping when he threw out his joints a year ago.
