I have reported it to animal control, and I am sure the only thing they did was send them a form letter stating that they were issuing a warning about the dog and that is about it. The only time I have seen them show up for anything was to clean up road kill or to take down a rabid dog. They could care less about anything else.
I guess I could push it, but nobody else in the neighborhood has a backbone so I am not going to be labeled the neighborhood troublemaker. Believe me, thats how it works. Say something and your labeled trouble. Let your dog roam around and nobody says a damn thing!
I haven't seen the dog lately, but that doesn't mean that they are still not letting it roam the streets at night(I have personally seen this).
