That's terrible! What an awful situation to be in.
Some ppl are so selfish they don't think through how it must be for the owners of a pet they've taken a liking to - we had a similar situation with a friendly little cat in our neighbourhood, it wore a collar and some dip-sh*ts who were visiting their friends took it home cos they assumed it was lost/abandonned! The owner got it back thankfully, so I hope you have a similar outcome.
Have you thought about contacting the local SPCA? They may be able to come up with some suggestions for what you can do. I own a dog and would be devastated in this situation. Keep us informed.
My goal in life is to be as good a person as my dog already thinks I am.
