In calif in my small town you have to have 3 ppl you aren't related to, to write letters to animal control. Heck I write an annoymous letter to the owner stating the problem, and I will have no problem calling the authorities every time it happens to show how inconvieant my life is. My BF goes to work at midnight and 2 dalmations bark at that. If i sit on my porch there they go again. Like the above mentioned its a pain. So try the letter and send several written differently and see if that works, has for me.
