Hi and Welcome to YT!
Sounds like she's seen a ghost! or something in the house has her terrified. Is she okay during the day? Do you have any other pets in the house? If not, I would try borrowing another dog to see if it has any kind of reaction similar to hers.... Maybe if another dog doesn't have the same reaction, she would see that and learn there's nothing to fear from watching the borrowed dog....
Did anything fall over at night, or fall on her? Mine get really freaked say if a box falls over by itself.... |
