There is nothing more dangerous than a pack of feral dogs. I recall an article about school children waiting for the school bus in rural Australia being menaced by dingoes. You know- the place that turned in their guns. Now their children are victuals for wild dogs.
We still have lots of guns - more now than before the buyback, despite the .gov.au - and the dingos don't seem to be making much of a dent in the supply of children
.
In all seriousness AFAIK the last time a child was taken by a dingo was some years ago, but that case is a good demonstration of how a problem can arise and be addressed. It took place at Fraser Island, just off the Queensland coast, which holds a remnant population of very pure bred dingos. It is a popular holiday spot, and for years people had been feeding dingos to bring them in for photos, leaving fish frames on the beach for them, leaving food out, strewing scraps about etc. As a result the dingos came to associate humans with food and also lost much of their shyness. There had been a couple of near misses but finally a boy was killed, and as a result a programwas put in place involving, among other things, providing secure food storage in campsites (and requiring people to use it), prohibiting feeding of dingos, prohibiting leaving of food scraps/fish frames etc, counselling visitors on the importance of not encouraging dingos etc. The rangers also shot a few dingos identified as a threat, and blokes were engaged to patrol with a slingshot to "sting" any dingos who were overly familiar, hanging around campsites etc, so as to instil a proper fear of humans in them.
It seems to be working - last time I was on Fraser the dingos were noticeably wary, and AFAIK there've been no more near misses let alone attacks.
Wild (feral) dogs are a bit of a separate issue, and a problem in some areas. These are often not far removed from domestic life and have little fear of people. Some are big too, derived from mixed breeding from working dogs, pig dogs and what have you. They breed up in National Parks (where shooting is not allowed) and emerge to attack livestock and (occasionally) menace people. Of course outside the National Parks they are fair game, but there's many farmers and others who'd prefer the National Parks administrators to play more of a part in controlling them.
