I would like to know why dogs in the North (and possibly elsewhere) do this, if they're provoked or so feral, they're almost wild and it's their way of surviving - are the news reports accurate? I can't help but link this to socio-economic issues and probably many other factors. Just wondering if you know of any research to direct me towards. I have read some of Dr. Boitani's work but nothing from Canada's North. Thanks.
