More to come yet DiNgO BoY but I don't have a lot of time at the moment to get my head in to gear for you.
Where do they all come from in Queensland? Well, of course, no one up here is breeding them!
But there is a considerable interstate surplus.
Re the Chewton numbers. When I first visited the place, not long after Mr Jacobs' death, it was a shambles. There were definitely well over 200 animals on the property and even a pack that had escaped and set up residence in the surrounding National Park. Dogs were fighting constantly, pups were being eaten at birth by other dingos, the Jacobs' residence had been invaded by dingos and had been destroyed to the point that it is still jokingly referred to by the new owners as "Chewed on Manor"! The Victorian Government was NOT pleased about the whole situation and had planned to eradicate all the dingos, raze the limited infrastructure on the place and return the property to National Park.
Enter the current owners who have turned the place around despite considerable opposition. It is now a dream home for dingos.
