Poor Bailey

We've had some problems with Bailey barking when we go to bed. Usually about 5-10 minutes and she's done though. We also noticed she started barking when we would leave to go somewhere (except in the mornings for work, for some reason.) But we assumed she would stop. I was backing out of the garage today and noticed a not on our garage entry door. It said "Not trying to be rude but your dog barks all the time when you're gone disrupting my evening. Could you find a solution, please." I know exactly who did, he's a member of the board. And he's actually been a pretty good neighbor, when we went to Florida we even gave him our phone numbers in case Bailey did bark alot. So we really can't be offended by the note, and I'm not. I'm just upset. Troy came and got me for lunch so we could talk about what we're going to do. We talked about giving her away, but technically since we got her at the ARL we're supposed to take her back there...NOT something I want to do. So then we talk about a shock collar. Typically I'm against them, but I think it's just because I hear about people abusing them and using them incorrectly. So I bought one...we just put it on her, except for today I only plan to use it when she's in her kennel but today I want to test it out. I took her potty, she barked at a dog across the street and then immediately shut up and sat down right by me. She didn't whimper or yelp, so I know it's not hurting her. Right now she's sitting on the couch pouting, I think she's mad at us. :(
