The whole story smells fishy to me, not your story, theirs. I, too, think you did the right thing morally and I hope legally, too. Isn't that just the way things are nowadays! (She says in disgust.) Someone pawns off that poor dog and the responsibility for its care and you are the one who is worried about the legality of what you did to rectify the situation. Things are upside down. Try not to worry too much about it. The dog is fortunate to be away from those people and in a home where people want her and will take good care of her.
