I agree with previous suggestion of mailing out what you wrote here to both the complainer and your landlord. I had a similar thing happen to me when I lived in a condo that allowed pets. One neighbor kept complaining that my puppy barked constantly throughout the day. I knew this to be untrue and I had other neighbors that knew this was untrue, but the person complaining was on the condo board and had a lot of weight as far as getting people fined. This is what I did. I wrote the compainant, and the condo board a letter outling how well trained my puppy was and how I was home most of the time so there was a constant effort made to keep barking to a minimum. I also reminded them that although I appreciated my neighbors privacy and right to quiet that there is not much anybody could do to prevent a puppy from barking once in a while and that I did in fact want my puppy to allert me to possible intruders, therefore I was pleased that he barked at times. I went one step further. I borrowed a video camera and made a tape of my puppy at different times and in different situations. I taped him while I was home and while I went out for an hour or two. I sent the board a copy and kept one for myself. It might seem extreme but it worked. I proved to the board that my puppy was a well behaved little guy and I shut down the complaints. There are a lot of folks out there that just plain and simply don't love our pets the same way we do and will complain no matter what we do, but at least you will show that you take a strong interest in your neighbors concerns and that you ARE a responsible pet owner. Hope this helps a bit.
