Studies of Captive NGSDs

Tracking the health, genetics and behaviors in captive NGSDs is an important aspect of our work. We seek to identify any health trends that are developing over the years. 

Some emerging health concerns have been identified, and the NGSDCS Science/ Research Board member is presently conducting a survey. The results of this study will be reported on this site.

The survey can be accessed via links on this website for NGSD owners (past & present) to participate. We welcome your survey input greatly! (See below)

Searching for Wild Singers in Papua New Guinea

Since 2016 the NGSDCS USA has supported field research lead by Ms. Rose Singadan, a PhD candidate at the University of Papua New Guinea. Rose, a biologist, has been an admirer of Singers for two decades. The Society supplied equipment including a GPS hand-held device, digital cameras, trail cameras, special DNA swabs designed for extended unrefrigerated storage, a portable solar panel, and specimen collection supplies. We also provided grants for expenses. Despite many setbacks, Rose and her assistants have scouted one location reported to have recent sightings of wild dogs, and started discussions with the people in a very remote mountain village about searching for Singers on their land. All land in PNG is owned by the tribe that has traditional claim to it, and permission to do anything in the area, even to pass through, must be approved and the local customs followed

Many PNG people who do not live in the mountains have never heard of the Singers, and Rose is developing educational materials to inform them about the value of the Singers to the ecology. Her hope is to secure agreements from the locals where Singers are verified to not hunt the Singers (most do not anyway) and to leave enough prey animals for the dogs to survive. Most of the rural village people hunt local animals as their main protein source, so to ensure their cooperation some way must be devised to replace the prey with another source, perhaps by supplying chickens for them to raise for eggs and meat. No markets in walking distance from the villages, and no roads at higher elevations. Everything must be carried into the mountains over often difficult foot paths.

The plan for the field study includes collecting photos of and DNA samples from village dogs. Scats and hairs from the wild Singers will provide DNA samples. These samples will be compared to the captive Singer DNA and the Wilton/Cairns admixture test done to determine percentage of domestic (village) dog genes vs. Singer/dingo genes in the samples.

After determining how rare the Singers are, and how stable the population is, so we are confident removing some will do no harm, the plan is to have locals collect one puppy from each breeding pair located to bring to the USA to expand the gene pool.

Another goal of the study is to collect the old myths and stories about the wild Singers. The Society will publish these as a booklet for the people of PNG, to help preserve that part of their traditional lore.
