Very sorry to hear that but lucky you only have the problem during late night hours. It seems that we hear our neighbor's dogs barking constantly...can't sleep, can't talk on the phone - can't even hear ourselves think. It is incomprehensible that barking nuisances are not enforceable and that surrounding residents have to go through so much protocol (Pasadena City District Attorney's Office) just to maintain peace and quiet for the neighborhood as a whole. We found it offensive that the Humane Society/Animal Control's response to our years of concern is, "Dogs bark --- that's just they do." That's not necessarily true. We have a dog and neighbors have commented, "Wow! Didn't even know you had a dog...its so quiet." Good luck to you...we can even get cooperation from other neighbors.
