For the past week or so....there has been a dog barking constantly!!! [Mad]

I don't know which yard it's coming from--since we have a field between my yard & the next block.

I have a headache right now....even over the tv you can hear it....whenever I let Cookie outside now...she'll start barking! I try not to let her bark because my new neighbor works nights & I also have consideration for others!!!

Help!!! I'm almost out of tylenol!!!! [Mad]
