Help Find Gigi: Blind, Deaf Shih Tzu Lost

Gigi is my 16 year old childhood dog who got out of the house this morning and wandered away. Because of her age she is now blind and deaf so she startles easily but is very friendly. She is slow and likes to lay so we are hoping she didn't wander too far. We just want to make sure she gets home to us safely. Small female black shih tzu with white on chest weighing approx 20lbs.
