It may be as simple as her eyesight and hearing changing as she is aging. What used to appear sharp may now look like a shadow or she may not hear as well. If you pick her up at all, she may find that uncomfortable so maybe it is that. If her eyesight is changing she may be more intimidated by you leaning over her.
I would go to the vet and ask for specific checks: Eyes, ears, hearing and sight and a senior dog blood draw panel including thyroid. I would also ask they assess her for arthritis and range of motion in joints as part of the physical examination. Is she fat? At 10 you want to keep her slim to help with any arthritis she might have.
