She is beautiful either way, but I prefer the shorter cut. It looks neater and makes her look like a puppy.
I had the same dilemma with Jake's hair. I love it long, but he looks so much neater with it short. The shorter cuts also make it so much easier for me to groom on a daily basis. So, since we live where we have cold winters and lots of snow, we decided to let it grow out in the winter for warmth since he won't wear clothes. He tends to get cold easy. We cut it shorter in the summer, and he is nice and cool and comfy. It's amazing how fast it grows! Also, it's so much nicer for his hair to be shorter in the summer because he LOVES to play and run around outside. If I would leave it long in the summer, it would be a grooming nightmare!
