What a little doll she is.
I think many groomers feel that they don't want to put them through the pain of getting many mats out of their hair and feel the humane thing is to shave them back. I wouldn't be too upset with your groomer and lucky you are to have a little one that looks good that way.
My Mother chose to shave my hair off at about one year old since it was coming in every way under the sun, I have pictures. To this day I am grateful so you too may find she will have an even nicer coat. Hope so.
