Did you change anything in her diet lately? And how bored is she? Being a new owner, one thing I’ve definately learned about the breed is that they don’t just “do” something, they obsess and focus so intently they become oblivious to all other things. Maybe do a trade-off and when she licks correct the behavior and then offer something in it’s place such as a chewy or toy. Kibble in a Kong is a great distractor and it’s hilarious to watch! Just an Idea, Good luck!
