I suppose most of the people who oppose this have never been bitten by a dog? It might affect your opinion on this issue I suppose.
Been bit by dogs, scratched up and bruised by dogs (admittedly, that's what happens when a fuzzy bundle of cuddles decides to launch from your lap,) scratched by cats (and being allergic, those were NEVER fun!), outright attacked by a possum once, and I still love dogs, cats... and... well, okay, I tolerate possums, but point stands.
And dogs are incredibly valuable work animals as well. While it is true that perhaps urban society doesn't need dogs, they still serve irreplaceable roles as guard animals, shepherds, bomb/drug detectors, guide animals, search and rescue, and so on. Your idea that they need to be banned would not make society safer, but it would no doubt make it far less safe.
