We keep our guys in puppy cuts and we think they are absolutely adorable. They too, run under the bushes, wrestle, roll and tumble. I can't imagine what they would look like with long hair. Right now the trees in our back yard are shedding their leaves - they bring in enough leaves now with puppy cuts. I can't imagine what a long coat would look like full of leaves!!!
Don't get me wrong, I think a Yorkie in a full coat is beautiful - but it just isn't practical for us.
