You sound like a very, very nice person to tolerate that .. I wouldn't go out of my way to be polite. If this dog has already bitten you (do your nieghbors know this?) you should talk to them immediately just how you spoke to us. Tell them that you have a right to your yard, and if the dog isn't trained, socialized, spayed, or whatever might help her and continues to bark and be aggressive just call animal control. Thats my advice, anyway . People really shouldn't be allowed to get away with this.

Also, is their Golden always outside? If so, you might want to inform them that "outside" dogs are almost always much more aggressive than dogs that are allowed inside. They develop strong protective instinct over their only known territory, which is the cause of many dog bites and most barking/annoying dogs.
