My dog lips curls but what does it really mean??? I have an 8 year old German Shepherd X that we rescued from a home 8 weeks ago. She is lovely & very sweet natured & has settled in well....but...she curls her lip at me if she is put outside & doesnt want to go, or if I am with my daughter when she is outside. He body language is ok - eyes are locked, her ears up (cant see her tail).
