You can escalate this neighbor dispute by seeking a civil restraining order, and she can escalate it further by calling the police and animal control about your (3? more than 3?) barking dogs which you apparently keep in your yard.
If you kept them inside, there'd be no problem, but you're the vulnerable one here as long as you keep your dogs outside where they apparently burden your neighbors with their noise. You don't mention what your citation was for, but you can expect more of them same. Since these are your neighbors that you have to live next to, I'd adopt a more cooperative attitude.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
I agree with my colleague - you have two issues and the first and foremost is addressing the issue of your dogs barking and disturbing the neighbors. As for the second issue of the neighbor blowing a whistle, spraying, etc, you have several options - first, address the dogs' barking, second, find some way to create privacy around the fence so she can't see the dogs, third, speak with a local attorney regarding your options. The Washington State Bar Association can give you a referral: www.wsba.org
If we do not have a signed fee agreement I am not your attorney and this is not legal advice.
It is wrong of your neighbor to taunt and spray your dogs. It is also wrong of you to allow your dogs to bark and create a nuisance in your neighborhood. If you kept your dogs from barking, you probably wouldn't have that problem.
