Not sure if you have seen this...it is the City of Plano Noise Complaint Form...specifically for dogs. :) Here is a little info from the form:
"A person wishing to file a complaint against the owner of a dog creating a disturbance by barking, howling or yelping is encouraged to maintain a dog Noise Complaint Log. A detailed, specific, and accurately kept log means a better chance of success if the case should be challenged in court. After this log is completed and signed, return to Animal Services"...

In Plano, there is a noise ordanice code:
Section 4-24(d) City of Plano Animal Services Ordinance, Public
Nuisances: It shall be unlawful and constitute a public nuisance
to keep any animal which, by causing frequent or long
continued barking, howling, crowing, meowing or other noise,
shall disturb any person of ordinary sensibilities residing in the
vicinity of the premise where the animal is kept, housed or harbored.
Any person in violation of this section may be found guilty of a
misdemeanor and incur penalties.
And here is a brochure about noisy animals and how to handle it:

Good luck! I too am a dog owner of two dogs and I feel horrible when they one bark too much or if I have let them out during the night and they bark. It is MY responsibility as a pet owner to make sure they are not being a nuisance to others. Kind of like kids...would you let them run all over a store screaming? :)
