Hi, first wanted to say that your Yorkie is adorable!
Her hair will grow back really quick but you'll have enough time to find another groomer before the next cut
. As to her behavior, I find that our furbabies can be really sensitive to our reactions. Maybe your furbaby picked up on your displeasure. I was told a couple of years ago, when my cocker got a bad cut and became moppy, to tell him how beautiful he looked and be really upbeat. This seemed to work for me! By the way
