Well, Yoda was out with his Mommy the other day and an elderly lady approached them because Yoda was so cute of course. She began talking about her Yorkie, which lived 18 years but died recently, and how her Yorkie just LOVED to eat M&M's! Yoda's Mommy was quite astounded, but I guess it takes quite a bit of chocolate to seriously injure a Yorkie? Not that we would ever give Yoda chocolate or anything, but from the sounds of it, that lady would give her Yorkie M&M's as a treat quite often! But I would think 18 years is probably on the upper spectrum of a Yorkie's life span, isn't it?
