Can you have someone hold her & distract her while you trim her? My Mimi hates scissors, so I have my Dad hold her head & he kisses her the whole time loll. When I need to trim her face, he holds her body, this calms her down. She loves my Dad, he's her person.
You can also try soft e-collars for grooming. A member here makes really nice one for our small Yorkies, here's her website:
The Kiss-E Collar
I have one that attacks any grooming tool, so I put the kiss-e collar on him to prevent him from getting hurt. It also blocks his view of the torture devices.
