Hold on everyone; This problem is not just a case of spite and revenge. It is a case where one neighbor is bullying another. Gramma do these people work nights and get upset if someone wakes them during the day? Do you own or rent? The very least you should do is have a face to face with them and tell them that you have the right to have a dog and the dog has the right to bark within reason. You can't let them control any part of your life. You shouldn't have to worry about your dog or your grandchildren making too much noise during the middle of the day so stop it! Tell them you will not put up with their nonsense and if they have any complaints then they can take them to the authorities in the proper manner using the procedure.
