Wow, you have no idea, how much what you said made sense. You have definetly given me some things to look in to. She is a border collie shephard. And I think you might be onto to something with the bordom. She usually spends her day in the kennel, but since she's started the barking fits, we have let her roam the house, while were not home. In the past four days she has calmed down a considerable amount. But will still bark. The neighbors do live fairly close, and the lady next door is deaf, so maybe she has a hearing aid, and that's what she hears. Thank you so much for your help. I will keep you posted if I find out anything.
