I will say, Dachshunds are by nature very vicious dogs. They're bred to spook up small prey. Yours may not be vicious, and I'm not saying I wouldn't be annoyed if I got reported for something, because I would. Even when we are wrong it burns a bit, so I give you that.
BUT: just as a person who loves dogs and knows a good deal about breeds, if I had my pick of dogs to run across unleashed, a Dachshund would not be high on the list lol. I remember two of them used to live by me as a kid, and I would be scared shitless of them. They make a terrible noise, and they are relentless when they go after you. Small or not, they can give people a start, especially people who don't like dogs.
I'd definitely go up to your house first and not report if it were me, but he may be genuinely terrified of it? And if she's always off the leash it may not be easy to do. And I'd hate to pay rent and not be able to bike down a certain street. Who knows...
