She will probably just say that her dog is howling and barking to protect her property,that seems to be the usual excuse of people who own dogs that are a noise nuisance.Dogs can be trained not to bark incessantly but only at real intruders,most dog owners are just too lazy to bother though. I have nothing against dogs btw, I just can't stand dog owners with no consideration for others. Let me know if you get anywhere with the local authority and I might contact them about my neighbour!
