I can't imagine how you must feel right now. Bell's young right now and has never been outside so I don't know what she would do if she were loose. But I know inside the house she runs to me when she gets frightened, so hopefully that's the case when she learns to go outdoors. My parents have a Chi and one time we were at our vacation home in Florida (it has a nice big fenced yard). We usually just let my parents Chi outside and he runs around, plays, goes potty etc. He doesn't stay out long and we usually check up on him frequently. Well one time I put him outside and a short time later I heard barking. Of course I headed outside to see what it was. Well I got outside and saw a guest had carelessly left the gate wide open after leaving! Taco (my parents Chi) was standing just inside the open gate barking at it! He knows the gate is always closed and I think was trying to alert us that it was open, as I didn't see anything else around to bark at and he was standing right in the opening lol. Keep us updated! I hope your pup makes it home safely!
