One thing I haven’t seen mentioned is how the people are sure it is the same dog barking, and can identify said dog. I live in a neighborhood where every other house has at least one dog, if not more. And some of the houses are duplexes, such that if the dog is barking inside the house, unless someone is right in front of the front door of the apartment, they just won’t know which side/dog is barking. Also, there are houses that are hidden behind other houses, and shared backyards.
For a while, I had a neighbor in my duplex whose dog barked at anything, all day long. Since I was a vet who lived alone (with a mostly nonbarking dog), I didn’t care. She didn’t take her dog out frequently, while I took mine out at morning and evenings, sometimes in the middle of the day, with occasional walks around the neighborhood. When someone complained of dog barking in the house (a duplex), I was the one who got the note. But how could they know, since both dogs were kept inside during the day, which one was it?
Later the neighbor moved and the complaint resolved. Then last year I got a new neighbor, who has the house behind mine (so hidden from the street in front of my house), and whose backyard abuts with the property I rent. She has a very large, barking dog. That barks… all the time. Yes, again, my dog got the complaint.
This time, though, I recorded my dog for a week while I was out at work (with the webcam). Other than ONE episode of barking of less than one minute, which sounded more like “guardian bark” (some stranger at the door), the rest of the video consisted of my dog sleeping and stretching for 10 hours every day. VERY boring. Oh, and I did catch (several times) that while my dog was curled up snoozing, you could distinctly hear other dogs barking in the neighborhood.
So one of my concerns with this type of ordinance would be proving you have the right dog. And also determine that and compare it with the rest of the neighborhood. Like I said, even if my dog barked and were removed, that leaves at least 10 other dogs, about a third of them barkers, around the neighborhood.
