In the current edition of The Big Issue, there's an article about a program in the Northern Territory - the Maningrida Dog Health Program. Photographer Dave Tacon accompanied Dr Ted Donelan, a Melbourne vet who regularly visits the area to administer the program, and there are interesting photos on Tacon's site.
The relationship of indigenous Australians to dogs varies in different places, but Maningrida is 'dog dreaming' country, where people have a special relationship to dogs and want to be free to live with as many dogs as they wish. There are some problems with aggressive dogs, though, and the Dog Health Program aims to help foster responsible dog ownership, both for the dogs' sake and for the safety of humans.
What I loved about the photos on Tacon's site was the way the dogs were an integral part of people's lives, lolling around with their human companions or joining them in their daily activities, with not a leash or collar in sight.
The University of Melbourne's Vet News has an article about a veterinary visit to Kunbarllanjnja Community.
