Some years ago, we farmed deer on our property in South East Queensland. We started catching the local feral Red Deer but due to their better adaption to the sub-tropics and tropics we sourced a herd of Rusa Deer.
Good dogs can handle these species of deer and it is wonderful to watch a clever dog adjust to the flight zone of livestock very different to sheep and cattle. Rusa can be very aggressive, approaching, rapidly, with stamping front feet and then breaking unpredictably, usually, leading part of the herd away with speed and determination. Useful dogs must have courage, cover and the ability to pat that flight zone bubble with skill and accuracy.
On one occasion we got a call about 150 Rusa Deer which had escaped the confines of the high fences and made their way down the valley some 14 Kms (8.5 miles) and were enjoying a pasture of irrigated rye grass. This was not good news to the owner of the farm as he needed the feed for his young stud Charolais bulls. It was suggested by many neighbours that the only solution involved rifles, sharp knives and plenty of volunteers.
