A person living in Canada has just as much right as anyone else in the world to research and own a particular dog (or anything else).  You, nor the Koolie Club of Australia, have patented sole rights to these dogs.  Wikipedia is all about correct information and NOT theories and your own ideas of what happened, what was and what will be.... Wikipedia is based on facts, which clearly has been stated on the German Coolie page and not the Australian Koolie page.
