Could they have transferred the dog from cargo to the passenger area in flight?

Nope.

I don’t know. I have seen movies and tv show where people go into the cargo area while the plane was in flight. I think they did that in Airforce One. Harrison Ford’s character hid in the Cargo Area when the plane was hijacked by terrorists. And I saw a stewardess and Castle go into the cargo area in an episode of Castle. So in Hollywood it is definitely possible.
