Pets expansion --My dog has been taken away -- Help me get her back

Not a cheat, but there might be a mod to help you out. When something like this happens my advice is to not save the game. Or save as - when you don't want to lose progress - and number the save. That way you can go back into the previous save with the dog still there, save it to the bin and place it into your household again using edit town. She's a cutie indeed!

ETA: I mean the library bin btw, that way she won’t have lost her progress.
