I live in a CYV neighborhood and at least 50% of us have dogs. Our dog barks once or twice to be let in, as do the dogs next door. Haven't heard a peep from the dog on our other side, but she was fairly recently adopted. The walls/fences probably do block noise, and there is no dog behind us. I never notice the dogs 2 and 3 houses down barking, although they must once in awhile.
I have heard a couple of dogs on the next street over bark a lot sometimes, when dogs are being walked past their house. I think those dogs used to spend more time in their garage, now I think they are kept inside more, probably due to the barking. Owners are snowbirds so they were not in the garage in hot weather. Don't think it's a problem anymore, so either the owners realized it or the dogs just got used to being here.
If you should have neighboring dogs who bark a lot, I would let the owners know, in a nice way, that they are barking a lot when they are gone. Maybe they don't know. Most dogs are inside when owners are out and about, and if a dog occasionally barks when people pass by, so what? Certainly if constantly barking dogs are a problem that the owner, when advised, is not resolving, then it's time to get Community Watch involved.
I would be a lot more concerned about constant loud parties on someone's patio or lanai. An occasional loud party is fine with me, especially if I am invited
. We are not talking loud rap or rock bands here.
