I don't know what may be going on with Bella, but she been jumping at every little noise. I will accidently hit the wall or counter top, and then she starts barking like someone is at the door. There are certain sounds on TV that she freaks out about also. Forget about it if a program has a bell sound to it.
I decided that this may be a problem when I just gave her a treat. I was talking to her as usual before the treat, then I said my usual "Good girl, you're my baby girl" (or something silly like that), and she jumped and barked, looking around the house, like someone else had said it.
What's got her so spooked???
