Oh my goodness, she looks SO CUTE!!!! My girls hate to be groomed, always have. It's like torture for them and for me. I keep them in puppy cuts similar to your baby's new cut, and they look cute and are happy that Mommy doesn't have to brush them all the time.
I agree that some dogs seem to love to be groomed and others do not. It's good that you realized that your darling prefers her shorter 'do and she looks so happy
