This is what happened to us. We move into our new house, new area, and Stella didnt settle as quickly as we hoped. She had plenty to do for the first week, had the garage to use at her leisure, and her bed and blankets and a couple of old shirts that we wore to bed for her. But, we found out a week later, she still barked all day. We had been here two weeks, and a council rep was on our doorstep, issuing a noise complaint. Thanks new neighbours, we feel so welcome.
The next week she had a soft muzzle on, then a citronella collar, plus extra training. Haven't heard anything since.
BUT, it made us feel really bad. Our dog has everything she could ever want and need, plus extra love. I was so worried that they would think we were bad owners, that I still (two years later) cannot really approach any of our neighbours as I dont know who made the complaint.
Please give them some more time to sort them out. I only wish they had knocked on our door, rather than getting the council to.
