I'm concerned that certain breeds of dogs have inbred tendencies to harm humans, and we've all heard about recent incidents of dogs killing people. These reports and my own personal experience suggests that Rottweilers may be on that shortlist of dangerous breeds. I've always been a dog lover, and get along fine with most dogs, but certain Rottweilers are just not social animals in my estimation. Naturally any animal can be loved and trained and controlled if the owner is responsible and capable of doing so. But other owners aren't responsible people, and the result of irresponsibility in the case of Rottweilers is often a dangerous animal. Well, I guess that's my entire rant, except to suggest that certain dangerous breeds of dogs should be required to have a special license -- much as gun owners are required to have a gun permit. When something is potentially dangerous, that seems necessary.
