This proposal has a decided risk of abuse depending on who is allowed to call in the police. Neighbor across the street claimed the Labrador we had was "vicious" despite his ability to make friends with toddlers and cats while leaving her Shelties on a small front lawn behind a fence they could easily jump despite having a good sized dog run with a gate--I know about the run because she owns the first house my parents owned locally and she only moved the dogs after the city made it clear that she would lose them if they weren't moved behind a regular fence which she did by building a tall fence that violated code and had to be modified--if she knew I was a gun owner, i am sure she would try to get my guns confiscated permanently
