My little girl Bella used to be such a tough little cookie but for the last 8 months or so she get's terrified of the bad weather. Wind dark clouds rain really even when it's not that bad it's like she knows something's coming.She tries to hide in the hall if noone is around and if we are on the couch she's right on top of us shivering. Poco has his own list of fears the truck the camera anything you have in your hand when you come near him.I know this is a chihuahua thing they shiver and shake sometimes for no reason. Just wondering what your babies are scared of.
