Bummer indeed! I know that feeling of wanting to smash something! Thats about the time i realize that Mom needs a time out...
I was ready to throw something at the groomer that shaved down the bridge of Pixies nose and between her eyes when she was about 4 months old... I saw red

when I picked her up!
Its been 2 months and the hair is just over an inch... long enough to curl around and poke her in the eye!

Its the "inbetween" stage! Its growing out much faster than I thought, but at the same time it feels like it will never catch up to the rest.... well, it never really will... But it is looking much better!
Chin up! I bet your amazing with the brush and a bow! Once it grows out a little, I'm sure that you'll be able to hide it!
