It seems like people miss the point nowadays that the over-regulation and over-governance of society are actually more a part of the cause of problems like dog violence than the solution. Where people are allowed to self-govern their pets, there are usually few problems. I find where I live fewer and fewer people are paying attention to dog licensing requirements and vaccination requirements, etc. Thankfully, the local government can't keep up and people seem to be managing just fine, though veterinary businesses may be suffering.
