I have this doll that my dog is almost afraid of, he always barks at her and he has never done this for any other doll of mine. I think something may be possessing the doll.
This entire depends on your beliefs and what you believe is possible. More than likely, there is a certain sent or 'vibe' that somebody passed onto the doll at some point, and the dog picks up on it and doesn't like it. But that doesn't mean that it's impossible that your doll could be possessed.
