Barking Dog . . .

I can't believe I'm blogging about this but I'm at the end of my rope and don't know what else to do. Here's the deal . . .

About a week ago a dog started barking in my neighborhood. "Bark" doesn't really describe this noise appropriately - it's more of a very high pitched yip that could shatter glass! I don't mind the occasional barking dog but this is constant - darn thing starts barking at 6:30 in the morning and we've heard it bark as late as 10:00PM! I know, I know, I'm not that old, 10:00 shouldn't be a big deal but when you have a 9mo. old baby that goes to bed at 7:00, 10:00 is suddenly a very big deal. This morning at 6:26 when the dog woke me up, I ran outside to see if I could find it/it's home/it's negligent owners and I narrowed my search down to 2 homes. I came home and settled down and decided to revisit the homes later in the morning so as not to say anything I might regret. Of course when I returned the neighbors were gone. I plan to go back around dinner time. I know it sounds crazy that I can't figure out which yard the barking is coming from but it's really hard to tell. I thought about peeking over the fence but I don't want anyone to think I've completely lost it. If I have to listen to that dog another day, I really am going to lose it though.

If you have any advice or have dealt with a similar situation, PLEASE HELP!!!
