Our neighbors who finally moved last summer built a dog run outside of their garage which just happened to be 9 feet from our bedroom wall. When we first moved in here, they would leave their 4 malamutes out there all night long -- howling at the moon. It was so bad, we couldn't sleep. Many nights I slept on the other side of the house in the family room. Then DS came along. His bedroom wall was also adjacent to this area. We started asking the neighbors to put their dogs in at night -- they claimed they couldn't because they were show dogs and needed an appropriate coat?? And, she told me she would hear them at night and think it was cute, roll over and go back to sleep - lucky for her, something we couldn't do.
Then we finally got fed up and started calling the police. They were tickets several times. The story goes on and on and gets worse and worse between us. Come to find out the area they were using was against village code and they had to remove it. Best thing that happened to our neighborhood was when they moved.
I can fully understand your problem and feel really bad for you. It sounds like it's going to be a tough battle. Good luck.
