He looks adorable!
When I take Pixie to the groomers, I stay with her, at least until she is older.I only have the groomer do the basics trim ears toes and toe nails lil bum. Once Pixie and I are more comfortable I will let her get a full spa expierence.
Maybe next time you can ask to stay until he is done and be more specific about what you want and offer to hold him when she trims his ears.
