Lady of Yorkies - good questions. Tieing the ears up means that one would take the hair stands near the ear base and pull these hairs into their topknot or tieing the strands of hair so that it make the ears go up more. This helps to correct a wide earset and makes the ears go up more (closer). Check your standard - you do not want a wide earset. Tieing the ears or a big no no! But there are some people that do it - everywhere - US and abroad.
