My first puppy Chibi was a very sweet and laid back puppy, he harldy got into anything, learned potty training right away and was pretty much a model puppy. He is now almost 6 years old and still the sweet dog he was so long ago, he has picked up some bad habits along the way but he iis just calmer and more well behaved than most. Just got lucky I guess- warning though lightning doesnt strike twice, if you ever get another yorkie it will probably be a trouble maker like my little Molli
